THE ACCESS UNIT AND PHI BATTERIES CONTAINED WITHIN THE UNIT MUST BE INSTALLED

ACCORDING TO THE PROCEDURES OUTLINED IN THIS INSTALLATION MANUAL AND THE PHI

BATTERY INSTALLATION MANUAL. ALL ACCESS UNIT OPERATION MUST BE IN ACCORDANCE WITH

THE SETTINGS AND CONFIGURATION OUTLINED IN THIS MANUAL. FAILURE TO ADHERE TO EITHER

THE ACCESS INSTALLATION MANUAL OR THE PHI BATTERY INSTALLATION MANUAL WILL VOID

YOUR WARRANTY. ALL ACCESS UNITS ARE PRE-PROGRAMMED FOR BATTERY CAPACITY ORIGINALLY

INSTALLED. IF ADDITIONAL CAPACITY IS NEEDED, CONTACT YOUR ORIGINAL INSTALLER AND LOCAL

CERTIFYING BODY PRIOR TO PROCEEDING.

1.0 - Important Safety Informaon

1.1 – Safety Instrucons

1. Before using the unit, read all instrucons and cauonary markings on the unit, the PHI baeries, and all appropriate

secons of this manual.

2. PHI baeries must be fully charged before commissioning the AccESS unit (i.e. before turning on connected loads). Failure

to do so will void the Warranty.

3. Use of accessories not recommended or sold by the manufacturer may result in a risk of re, electric shock, or injury to

persons and will void the Warranty.

4. Verify system sengs are in compliance with the Baery Warranty and Baery Installaon Manual (which take

precedence). Violang Warranty condions specied in these documents will void the Warranty on the PHI baeries.

5. Consult the Integraon Guide for Sol-Ark equipment sengs as well as relevant warnings and noces. All Integraon

Guides are posted on SimpliPhi’s Product Documentaon web page (hps://simpliphipower.com/product-documentaon/).

Violang Warranty condions specied in the Sol-Ark Integraon Guide will void the Warranty on the enre AccESS unit,

not just the SolArk equipment.

6. Each AccESS system contains PHI 3.8 baeries. Although each PHI 3.8 baery contains both a circuit breaker and an

internal BMS with circuitry that protects the PHI 3.8 baery cells from overcharge, over-discharge and excessive load

amperage, the PHI baeries must always be installed with appropriate Balance of System equipment sengs and power

electronics to protect the PHI 3.8 from open solar PV voltage and other high voltage charging sources. Do not aempt to

replace exisng power electronics without SimpliPhi’s wrien approval. Failure to adhere to installaon protocol will void

the Warranty.

7. Verify polarity at all connecons with a standard voltmeter before:

A. Energizing the system and

B. Turning the PHI 3.8 circuit breaker’s “ON/OFF” switch to the “ON” posion. Reverse polarity at the PHI 3.8 baery

terminals will void the Warranty and destroy the PHI baeries.

8. PHI baeries pose some risk of shock or sparking during the installaon and inial wiring and connecon process. This is

consistent with all other baery-based storage formats. Be sure to turn the built-in circuit breaker to the “OFF” posion to

minimize the risk of shock or sparks during the installaon and commissioning of the system.

9. To avoid a risk of re and electric shock, make sure that exisng wiring is in good condion and that wire is not undersized.

Do not operate the AccESS unit with damaged or substandard wiring. This will void the Warranty.

10. Do not operate the AccESS unit if it has been damaged in any way during shipping or otherwise.

MODEL NO. 050000, 050001

11. Only use a SimpliPhi approved LFP baery charger if ancillary charging is required before installaon, tesng or

troubleshoong. Failure to use a SimpliPhi approved LFP baery charger will damage the PHI 3.8 baery and void the

Warranty. Refer to the PHI 3.8 Manual for details regarding SimpliPhi-approved ancillary charging equipment.

12. To reduce the chance of short-circuits, always use insulated tools when installing or working with this equipment.

13. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with electrical equipment.

14. The AccESS unit does not have any user-serviceable parts. Do not disassemble the inverter except where noted for

connecng wiring and cabling. See your Warranty for instrucons on obtaining service. Aempng to service the

components inside the AccESS unit yourself may result in a risk of electrical shock or re and void the Warranty. Internal

capacitors remain charged aer all power is disconnected – wait 10 minutes before servicing.

15. To reduce the risk of electrical shock, disconnect both AC and DC power from the AccESS unit before aempng any

maintenance or cleaning or working on any components connected to the inverter.

1.2 – Safety & Protecve Features

1.2.1 – Baery Breaker

All PHI 3.8 baeries within the AccESS unit are outed with an hydraulic/magnec circuit breaker which will show a

white base when tripped. This breaker increases safety during shipping and installaons and allows the PHI 3.8 baery

to eecvely be turned “OFF” or “ON.” The breaker works in conjuncon with the built-in baery management system

(BMS) and creates addional safety, eciency and funconality to the overall power storage system.

SIMPLIPHIPOWER.COM | 805-640-6700 | BSREV202111141140

MODEL NO. 050000, 050001

PHI baeries pose some risk of shock or sparking during the installaon and inial wiring and connecon process. This is

consistent with all other baery-based storage formats. Be sure to turn the built-in circuit breaker to the “OFF” posion

to minimize the risk of shock or sparks during the installaon and commissioning of the system. Use of insulated gloves,

clothing and footwear is always recommended when working in close proximity to electrical devices. Cover, restrain or

remove jewelry or conducve objects (metal bracelets, rings, belt buckles, metal snaps, zippers, etc.) when working with

any electrical or mechanical device. Cover or restrain long hair and loose clothing when working with any electrical or

mechanical device.

PHI baeries do not vent any harmful gasses, and do not require special venlaon or cooling.

PHI baeries are not capable of thermal runaway. As with any baery, if the cells are severely damaged due to physical

abuse incurred outside of warranted specicaons, it can cause electrolyte leakage and other failures. The electrolyte

can be ignited by an open ame. However, unlike other lithium ion baeries (e.g. LCO, NCM, and NCA), the PHI baeries’

electrolyte and other material components generate a limited amount of heat.

1.2.2 – Charging at Temperatures Below Freezing

It is important to take necessary steps to determine the temperature of the PHI 3.8 baery prior to charging the baery, as

the baery may otherwise be adversely impacted.

CAUTION: Circuit Breakers, Disconnects and Fuses should be employed throughout several points of a

power storage and generaon installaon to eecvely isolate and protect all components of the system

to safeguard against faults, short circuits, polarity reversals or a failure of any component in the overall

system. Fuses, breakers, wiring rangs and values should be determined by established standards and

evaluated by cered electricians, licensed installers, and regional code authories. Although each PHI 3.8

baery contains both a circuit breaker and an internal BMS with circuitry that protects the Lithium Ferrous

Phosphate cells from overcharge, over-discharge and excessive load amperage, the PHI baeries must always

be installed with a charge controller and the appropriate sengs to protect the PHI 3.8 baery from open PV

voltage and other high voltage charging sources.

The PHI 3.8 Baery Management System (BMS) and built-in circuit breaker alone will not protect the PHI

baeries from extreme electrical condions. Failure to adhere to installaon protocol will void the Warranty.

CAUTION: Verify polarity at all connecons with a standard voltmeter before 1) energizing the system

and 2) turning the PHI 3.8 circuit breaker’s “ON/OFF” switch to the “ON” posion. Reverse polarity at the

baery terminals will void the Warranty and destroy the PHI baeries.

CAUTION: Do not aempt to charge the PHI 3.8 baery below 32° F (0° C). Although cold temperatures do

not harm PHI baeries, aempts to charge at subfreezing temperatures can adversely aect SOH and cycle

life, and will void the Warranty. If the PHI 3.8 baery must be charged below 32° F (0° C), the rate of charge

must be at no more than 5% of the PHI 3.8 baery’s rated capacity (C/20).

MISE EN GARDE: Ne pas charger la Baerie PHI en dessous de 0° C (32° F). Tout chargement à des

températures de congélaon peuvent nuire à l’état de santé et la durée de vie de la baerie, et Annuleront la

Garane. Dans le cas ou la Baerie PHI doit être chargée en dessous de 0° C (32° F), le taux de charge ne doit

pas dépasser 5 % de la capacité nominale de la Baerie PHI (C/20).

MODEL NO. 050000, 050001

1.2.3 – Baery Management System (BMS)

The PHI 3.8 baeries within the AccESS unit are manufactured ulizing Lithium Ferrous Phosphate (LFP) cells, which are

produced under exclusive patented licensed technologies, as well as proprietary materials, architecture, manufacturing

processes and baery management system (BMS). This assures the highest grade and quality, longest cycle-life, greatest

eciency and freedom from material impuries, toxicity and hazardous risk.

Each PHI 3.8 baery within the AccESS unit contains circuitry that protects the Lithium Ferrous Phosphate cells from

overcharge, over-discharge and excessive load amperage. If the values specied are exceeded, the protecve circuitry will

shut down the ow of electricity to/from the PHI baeries. In some cases, this will result in the need to manually turn the

baeries and inverter back on. Oen, inverter system sengs will be saved within the inverter memory storage and will not

need to be reset. This is not an absolute standard but is common amongst most inverter/chargers and should be ancipated

if the PHI baeries go into a state of selfprotecon and shut down the ow of electricity.

1.2.4 – PHI 3.8 Baery Connecon Terminals

The PHI 3.8 baeries are equipped with two 3/8’’ threaded studs with a lock washer and nut. The red colored high

temperature molded insert connecon is for the posive lead. The black colored high temperature insert connecon is for

the negave lead.

CAUTION: Do not aempt to loosen the large brass nut at the base of the terminals. This will void the

Warranty.

MISE EN GARDE: Ne pas desserrer le gros écrou en laiton à la base des bornes; cela endommagerait la

Baerie PHI et Annulerait la Garane.

CAUTION: Only use a SimpliPhi approved LFP charger if ancillary charging is required before installaon,

tesng or troubleshoong. Failure to use a SimpliPhi approved LFP charger will damage the PHI 3.8 baery

and void the Warranty. Refer to the PHI 3.8 Manual for details regarding SimpliPhi-approved ancillary

charging equipment.

CAUTION: While the BMS and internal circuit breaker protect the PHI baery from extreme electrical

scenarios, neither will prevent the PHI baery from operang outside the recommended operang

parameters. Rely on Balance of System equipment programming to operate the baery according to

recommended parameters, as outlined in the Sol-Ark Integraon Guide.

MODEL NO. 050000, 050001

CAUTION: Do not reverse polarity. It will void the Warranty. Use a voltmeter to check polarity before

connecng terminals.

MISE EN GARDE: Ne pas inverser la polarité. Inverser la polarité Annulera la Garane.

Water Resistant Cable Boots are also included and will be in place when your units arrive. The boots are to be placed over

the cable terminaons and will stretch to form a water-resistant seal around the base of the molded inserts and terminal

connecons.

1.3 – Limitaons of Use

The PHI 3.8 baeries within the Sol-Ark AccESS are designed to operate at a connuous discharge rate of 1.92 kWDC each,

across a large operang temperature range, as seen in Table 1.0 above. The SimpliPhi AccESS does not require an increase

in sizing nor any special compensaons when determining the size of the energy storage and management system under the

circumstances and condions seen in Table 1.0 above. Each AccESS unit comes pre-programmed to maximize the performance

of the PHI 3.8 baery bank. Sengs are password protected and require access to the lockout password by a qualied installer

for modicaon.

PHI 3.8 baeries within the AccESS unit do not need to be de-rated unless running connuously at more than 90% capacity, at

temperatures below 0° C, or above 45° C. To achieve higher, warraned cycles of 10,000, the PHI 3.8 baeries are operated at

80% maximum Depth of Discharge (DOD). The AccESS comes preprogrammed for 80% DOD. Please contact SimpliPhi Power

Technical Support if alternave sengs are desired. Please also refer to operang temperatures and inverter sengs in this

Manual’s Programming secon.

3.1.1 – Design Parameters: Maximum Sizing Guidelines

Below are the maximum sizing guidelines for installaons of the AccESS:

• Maximum AC Grid input / output OCPD = 60 A double-pole

• Maximum DC coupled PV array = 13 kWDC (per Sol-Ark-12K)

• Maximum AC coupled PV array = 9.6 kWAC (per Sol-Ark-12K)

3.2 – System Sizing for Your Installaon

The number of PHI 3.8 baeries within the AccESS unit(s) should be specied in terms of total rated storage capacity and

instantaneous power rang before the inial installaon based on the goals and objecves of the project. All PHI 3.8 baeries

are balanced during nal producon and tesng stages. Following proper wiring guidelines ensures that a system will not require

any manual balancing processes.

3.7 – Pad Mounng

3.7.1 – Pad Requirements

The AccESS must be installed and secured on level concrete. For a pre-cast concrete pad, a 4” minimum thickness is

required. The pad should be 3” wider than the AccESS on all sides (34” x 22” x 4”).

The AccESS is not suited for wall mounng. Any aempt to wall mount the AccESS unit will Void the Warranty.

3.7.2 – Pad Mounng the SimpliPhi AccESS

Six 1-inch knockouts are located in the base of the AccESS for tool accessibility when mounng the AccESS to the concrete

pad. Cover knockout holes with sealing tape aer pad mount installaon, and prior to installing the PHI 3.8 Baeries into

the base of the cabinet. Not all knockouts have to be used, depending on the dierent assets built into the AccESS system to

meet the customer’s needs. Any aempt to wall mount the AccESS unit will void the Warranty.

Secure the AccESS to the concrete with concrete anchors, such as threaded rods, masonry bolts, or carriage bolts, minimum

½” diameter. Exisng concrete oors in the garage or other areas are adequate “mounng pads” if the thickness meets the 4”

3.8 – Wire Run Lengths

Two limiter sensors are included with the AccESS Sol-Ark. The limiter sensor wires are 10 feet long, and are extendable up to 50

feet using equipment from Sol-Ark (contact Sol-Ark directly at 972-575-8875; [email protected]). Consider this distance when

deciding the Sol-Ark AccESS unit’s locaon relave to the home’s main breaker panel.

3.9 – Sub-panel or Transfer Switch Kit Installaon & Wiring

All AccESS Sol-Ark systems must incorporate either an Essenal Loads sub-panel or the 10-circuit transfer switch kit available

directly from Sol-Ark (see Figure 7.0). In the case of o-grid systems, all the home’s loads are on the Essenal Loads panel,

thereby making the Essenal Loads panel the main house breaker panel. Any distance is permissible between the AccESS Sol-Ark

and the Essenal Loads panel or Sol-Ark transfer switch kit, provided wire sizing and voltage drop is in accordance with local

codes.

Prior to the AccESS Sol-Ark’s installaon, determine which of the home’s circuits will be located either on the Essenal Loads

panel or the Sol-Ark transfer switch kit. Consider the following:

A. The Sol-Ark’s Load Output is protected by a 63 Amp double-pole breaker.

• When grid/generator-connected, the maximum connuous power the Sol-Ark can deliver to the Essenal Loads panel is

63 Amps at 240VAC (15.12 kWAC pass-through).

• When o-grid, the maximum power the Sol-Ark can deliver to the Essenal Loads panel (also considered the main house

breaker panel in an o-grid applicaon) is 37.5 Amps connuous at 240VAC (9.0 kWAC) and 67 Amps peak at 240VAC

(16.08 kWAC) for 10 seconds.

B. The Sol-Ark transfer switch kit (if used instead of an Essenal Loads panel) can house a maximum of 10 circuits, all of

which must use non-GFI breakers. Contact Sol-Ark (972-575-8875, [email protected]) for transfer switch kit purchase

and installaon instrucons; It is not included in the AccESS Sol-Ark.

4.0 – Installaon & Wiring

This secon covers how to install the PHI 3.8 baeries within the AccESS unit, torque values, communicaons and network

preparaon and how to wire the AccESS unit. It also provides guidance on how to install oponal AccESS unit components/

accessories.

4.1 – Basic System Conguraon Concepts

Safe and reliable installaon requires trained and cered technicians. The following discussion is a basic primer. Due to the

variety of systems and components in the eld, all possible scenarios are not covered. This is not the purpose of this secon of

the manual. Refer to professional installers regarding your system and its components and specicaons. We encourage you or

your installer to contact us with any specic quesons for technical support. We are commied to working with you and your

installaon team to achieve a safe, reliable storage system that will provide years of maintenance free service.

4.2 – PHI 3.8 Baery Installaon within the AccESS

1. Mount the AccESS unit on level concrete.

2. Make sure all PHI baery module circuit breakers are in the OFF posion. Prepare the baery modules for

installaon by removing all plasc terminal covers, 11/16” stainless steel hex nuts and 3/8” lock washers from

the baeries’ terminals and set aside.

4. Aach interconnecng busbars onto the baeries’ terminals. Each posive busbar parallels one set of two or three baeries

(posive to posive to posive), and each negave busbar parallels one set of two or three baeries (negave to negave to

negave). 2 baery interconnecng busbars ulize a 31”, 2 AWG cable. 3 baery inconnecng busbars ulize a 25”, 2/0

cable.

5. Secure the busbars to the baeries’ terminals using a 11/16” wrench socket to ghten the 3/8” lock washers and 11/16”

stainless steel hex nuts (originally included on the baeries). Tighten the nuts to 160 in-lbs.

6. Connect the included cables from the interconnecng busbars (secured to the baeries) to the 5-point terminal busbars

(see above). All connecons are in parallel: each posive cable connects from each interconnecng posive busbar to the

posive 5-point terminal busbar, and each negave cable connects from each negave busbar to the negave 5-point

terminal busbar (refer to Figure 11a and 11b on page 21).

7. Leave the PHI 3.8 baeries’ built-in breakers in the “OFF” posion unl the basic funconal test.

The PHI baeries’ charging regimen is not temperature compensated; do not include a Baery Temperature Sensor (BTS) wiring

connecon.

CAUTION: Adhere to all baery installaon instrucons as outlined in the PHI Baery Installaon Manual;

this manual does not substute the PHI Baery Installaon Manual.

CAUTION: PHI 3.8 Baeries must be fully charged before commissioning the AccESS unit (i.e. before

connecng loads for the rst me). Failure to do so will void the Warranty

CAUTION: SIMPLIPHI DOES NOT REQUIRE THAT THE PHI 3.8 BATTERIES WITHIN THE ACCESS BE

GROUNDED. IF A DC SYSTEM GROUND IS REQUIRED, ENSURE THAT THE SYSTEM BONDING IS DONE

IN ONE LOCATION ONLY, AND THAT ALL CONDUCTORS AND CONNECTIONS COMPLY WITH ALL

APPLICABLE NEC AND LOCAL INSTALLATION CODES.

• Addionally, the GEN port has a relay since it typically connects to a generator that would allow

for a physical disconnect to the GEN breaker. Therefore, if you were AC coupled with a unit that

does not comply with UL1741SA, connecng it to the GEN port would be required because the

4.5.2 – Making AC Connecons

AC Landing Points – Terminal Blocks

The AccESS is equipped with mulple knockouts on either side of the unit for accessibility to the Sol-Ark’s AC connecons.

All AC connecons are rated at 120/240 VAC. The bi-direconal grid port can also support two out of three phases of a 208

VAC grid connecon (the two phases being L1 and L2, 120° out of phase).

The Sol-Ark equipment includes the following:

• Bi-direconal Grid Port (AC In/Out): 63A double-pole breaker

• Bi-direconal Generator Port: 50A double-pole breaker

• Load Output (AC Out): 63A double-pole breaker

Figure 14.0 below shows the “Grid,” “Generator,” and “Load” connecon locaons. Also highlighted are the neutral and

ground AC terminal blocks.

Grid AC Wiring

1. Install a double pole 60A breaker in the main house breaker panel. Best pracce dictates that this 60A 2P breaker be

installed at the opposite end of the busbar from the main breaker (typically at the boom of the main house breaker

panel).

2. Include an External AC Disconnect (with handle) between the 60A 2P breaker in the main house breaker panel and

the Sol-Ark’s “Grid” port.

• The External AC Disconnect must be sized larger than 60A and include a knife blade switch.

Generator AC Wiring

Generators wired to the Sol-Ark Split-Phase systems must be rated at 240VAC. Generators wired to the SolArk Three-

Phase systems must be rated at 208VAC. Installaons outside North America that incorporate generators rated at 230VAC

/ 50Hz can be wired to the Sol-Ark, provided there is no Neutral wiring connecon.

Generators can either be wired to the Sol-Ark’s Generator Input Port or to the Sol-Ark’s Bi-direconal Grid Port.

In grid-connected systems, generators cannot be wired to the Grid Port. However, the Sol-Ark’s Generator Input Port may

need to be ulized for purposes other than the generator’s connecon. AC Coupled systems or systems ulizing the Sol-

Ark’s Smart Load funconality are wired to the Sol-Ark’s Generator Input Port. In such scenarios, a whole-home generator

transfer switch is necessary to incorporate a generator into the system:

Figure 15 - Generator Wiring in Grid-Connected AC Coupled Systems

It is also acceptable, but not required, to use a whole-home generator transfer switch when the Generator Input Port

does not need to be ulized for an AC Coupled solar PV array or Smart Loads. This setup is typical for larger (10-30 kW)

generators. In o-grid systems, Sol-Ark recommends that the Grid Port be used for generator connecons.

Inverter Charger Grounding

The Sol-Ark includes a ground busbar (outlined in Figure 14.0). A wiring connecon must be made between the Sol-

Ark’s ground busbar and earth ground using appropriately sized equipment grounding conductors. The Sol-Ark’s ground

busbar accepts wire sizes up to 4 AWG. System grounding must be done according to all applicable NEC and local

installaon codes.

CAUTION: Adhere to the programming instrucons in the “Generators” sub-secon of Secon 5.3

(Conguring the Sol-Ark) in this Manual when incorporang a generator into the system

4.5.3 – AC System Bonding

Mulple AC Neutral-to-Ground Bonds

Verify that only one neutral-to-ground bond exists in the system. Having more than one neutral-to-ground bond in a

system violates local electrical codes, may create a shock or re hazard, and may cause some sensive equipment to

malfuncon. The Sol-Ark’s neutral busbar accepts wire sizes up to 4 AWG.

Failure to follow these instrucons can result in death or serious injury and will void the Warranty.

System bonding refers to connecon (bonding) of one of the current-carrying conductors of an electrical system to ground.

This creates a “grounded conductor” or “neutral” that is at ground potenal but is separate from the equipment ground

conductor. System bonding must be done at only one locaon. Procedures for system bonding vary between on-grid and

o-grid systems.

System bonding for on-grid systems

The Sol-Ark does not include a connecon between neutral and ground. The AC input neutral is already bonded to ground

by the incoming ulity grid system. Do not connect the neutral to ground in any addional locaon.

The Sol-Ark does not switch or disconnect the AC neutral in any mode of operaon, so even in invert (back-up) mode, the

inverter load sub-panel neutral is bonded to ground by the ulity grid system. It must not be grounded again in the inverter’s

load sub-panel.

System bonding for o-grid systems

In a system without a generator, or with a generator that does not provide a grounded neutral, you must make the

connecon from neutral to ground in the Essenal Loads panel (the inverter’s load sub-panel), which is actually the home’s

main house breaker panel in an o-grid system.

In a system with a generator that provides a grounded neutral, no addional connecon from neutral to ground is needed. In

this case, do not connect neutral to ground in the Essenal Loads panel (the inverter’s load subpanel).

AccESS Sol-Ark System Solar PV Array Sizing

The Sol-Ark-12K’s built-in MPPT charge controller specicaons are:

• Quanty of built-in MPPT charge controllers per Sol-Ark-12K = 2

• Quanty of PV ports per MPPT charge controller = 2

• Total quanty of PV ports per Sol-Ark-12K = 4

• MPPT charge controller starng voltage = 125VDC

• Maximum DC Voltage input per MPPT charge controller = 500VDC

• MPPT charge controller voltage range = 150-425VDC

• Maximum ISC current input per MPPT charge controller = 25A

• Maximum operang current input per MPPT charge controller = 20A

• Maximum baery charging current per Sol-Ark-12K = 185A

CAUTION: It is crical that the solar PV string’s voltage does not exceed 500VOC; voltage greater than

550VDC will damage the Sol-Ark equipment.

To properly congure solar PV modules to the Sol-Ark’s built-in charge controllers:

1. Due to the charge controller’s starng voltage of 125VDC, calculate the minimum number of solar panel modules

needed to meet this target voltage at the module’s maximum power voltage (VMP).

In this example, consider the Canadian Solar KuPower CS3K-300 solar PV module with a VMP of 32.5V at Standard Test

Condions (STC).

• Four modules in series are required to meet the charge controller’s minimum MPPT tracking voltage requirement:

125V ÷ 32.5V = 3.9 (round up to the next whole number).

MODEL NO. 050000, 050001

2. The charge controller’s maximum DC voltage input is 500VDC. Temperature aects the solar PV module’s voltage

output: voltage increases as temperature decreases. To calculate the maximum number of solar panel modules in series

per PV string, consider the module’s open circuit voltage (VOC) rang, temperature coecient and lowest expected

temperature at the installaon site.

In this example, the KuPower 300W module has a VOC of 39.3V at STC, a STC temperature of 25°C, and a VOC

temperature coecient of -0.29%/°C.

To calculate the solar module’s VOC in an extreme low temperature condion of, say, -10°C:

• Eleven modules is the maximum allowable number of modules in series to prevent the solar PV string from exceeding the

charge controller’s maximum voltage input rang even in the coldest weather condions at the installaon site: 500V ÷

43.3V = 11.5 (round down to the next whole number).

• Eleven modules in series at the KuPower 300W module’s VMP rang of 32.5V at STC also equates to 357.5V, well

within the charge controller’s 150-425VDC maximum power point tracking range.

MODEL NO. 050000, 050001

3. The charge controller’s maximum short circuit current (ISC) input is 25ADC. Temperature also slightly aects the solar

PV module’s current output: current increases as temperature increases. However, because the temperature coecient

is negligible, it is acceptable to simply use the module’s ISC rang at STC for the following calculaon.

To calculate the maximum number of solar PV strings per charge controller in this example, consider the KuPower 300W

module’s ISC at STC: 9.82A.

• According to this calculaon, two solar PV strings is the maximum allowable number of strings per charge controller:

25A ÷ 9.82A = 2.5 (round down to the next whole number).

• Although the Sol-Ark contains only two solar PV string inputs, more than two strings in parallel can be wired to the Sol-

Ark. If more than two strings are connected in parallel to a single charge controller, each string must be fused (refer to

page 10 of the Sol-Ark-12K Manual).

• Three solar PV strings in parallel at the KuPower 300W module’s IMP rang of 9.24A equates to 27.72A at STC, above

the charge controller’s operang current input limit of 25A. Whereas two solar PV strings in parallel at the KuPower

300W module’s IMP rang of 9.24A equates to 18.48A at STC, well within the limits of the charge controller’s operang

current input limit of 20A. Therefore, in this example, no more than two strings in parallel per charge controller should

be used.

Based on calculaons #2 and #3 above, a maximum two parallel strings of eleven KuPower 300W modules in series can be

wired to each of the Sol-Ark-12K’s two charge controllers.

4. The charge controller can be paired with a maximum 6,500 Was of solar PV Waage.

In this example, the KuPower 300W module has a Maximum Power (PMAX) rang of 300W at STC.

• 21 modules are the maximum allowable number of modules that can be paired per charge controller:

6,500W ÷ 300W = 21.6 (round down to the next whole number).

5. The Sol-Ark-12K (with two built-in charge controllers) can be paired with a maximum 13,000 Was of solar PV

Waage.

In this example, the KuPower 300W module has a Maximum Power (PMAX) rang of 300W at STC.

• 43 modules are the maximum allowable number of modules that can be paired per Sol-Ark12K:

13,000W ÷ 300W = 43.3 (round down to the next whole number).

Considering all ve of the above calculaons, and maintaining equal elecrical characteriscs among parallel strings, the

opmal solar module conguraon in this example is wiring a maximum two parallel strings of ten KuPower 300W modules

in series to each of the Sol-Ark-12K’s two charge controllers, for a total of 40 modules paired with the Sol-Ark-12K.

4.5.5 – Limiter Sensor Wiring Connecons

The Sol-Ark AccESS installaon may include limiter sensors. Limiter sensors are required in the following applicaons:

• Limited to Home mode

• Time of Use Selling mode

• Systems that include both a generator and grid connecon

Install limiter sensors on incoming electrical service wires L1 and L2, at the top of the main house breaker panel (refer to Sol-

Ark’s diagram within their manual).

Verify the limiter sensors’ proper sense and direcon by adhering to the Sol-Ark manual’s “Tesng and Powering Up Sol-Ark”

instrucons in the Sol-Ark Manual. If applicable, perform the following checks aer compleng Steps 1 and 2 outlined in the

Basic Funconal Test Secon 4.5.6 below:

If MCU SW = 1654 or higher, an auto learn funcon avoids all this.

• Using AC mul-meter, verify L1 voltage on AC in/out is 0Vac with main L1 connecon in panel. Same for L2.

• To verify sensor connecons to Sol-Ark, try removing one sensor from the main L1 connecon. The power should drop

to 0W.

• To verify proper sensor direcon, with any loads in the home, the HM: +was will be posive. If you turn on solar panels

and turn enable Grid Sell, you should see HM: -was if you are producing more power than the loads are consuming.

And if you turn on limited power to Home mode, then HM: ~0 was to zero the meter (system matches the loads to

within 99%).

4.5.6 – Basic Funconal Test

The following procedure should be followed once the installaon is complete and before it is put into service.

Step 1: Conrm All Connecons

Aer the AC and DC wiring has been installed and connected, check that all connecons are correct and secure.

Step 2: Apply Baery Power to the Inverter

1. Measure the voltage and check polarity at all baery connecon points. Measure the enre PHI baery bank’s voltage

and polarity on the Sol-Ark’s DC Posive and DC Negave connecon points, outlined in Figure 18.0 below.

Note: The Sol-Ark includes a 250ADC Disconnect breaker.

MODEL NO. 050000, 050001

2. Supply DC power to the Sol-Ark inverter by turning ON the ON/OFF buon on the front of the SolArk unit.

3. The inverter will power up and the inverter display panel will turn on.

Step 3: Verify Inverter Programming

Although the AccESS Sol-Ark is pre-programmed to the correct baery charging parameters, the Sol-Ark equipment

oers dierent funconality based on various other sengs. Refer to this Manual’s Programming secon 5.0 for more

informaon. Update rmware to the latest version.

Step 4: Apply DC and AC Power to the Inverter

Turn all relevant DC and AC disconnects ON. When rst commissioning the system, leave the Sol-Ark’s Load Output breaker

OFF, and all circuits in the main house breaker panel OFF (if the Sol-Ark is programmed to a mode of operaon in which the

baeries discharge to the main house breaker panel; refer to Secon 5.3 of this Manual for more informaon on the Sol-

Ark’s modes)

Step 5: Fully Charge the Baery Bank Prior to Powering on Loads

A connecon to an AC power source will result in the Sol-Ark automacally charging the baeries from that power source

when the Sol-Ark is turned ON.

If the system does not include any AC power source, and only solar PV as the baeries’ charging source, turn on the PV

disconnect and wait unl the PHI baery bank has had a chance to charge fully via solar power before turning on any loads.

For DC Coupled systems, the solar PV array’s ON/OFF switch is on the le hand side of the Sol-Ark unit.

Step 6: Turn on Loads

Fully charged PHI baeries will reach a charging voltage of 54.4 – 56 VDC and will then “rest” at approximately 53.3 VDC

as soon as they are no longer acvely charging. At this point, turn on the Sol-Ark’s Load Output breaker and main house

breaker panel circuits, if applicable.

4.5.7 – Lockout / Tagout

Step 1: Detailed procedures for equipment

Begin by making sure you’ve idened the equipment correctly and accurately, including its specic locaon. Next,

determine the correct procedure for shung down and restarng the equipment. Detail that procedure, step by step, in

wring. Consider all of the energy sources that may be connected to the equipment. Be very specic, because ambiguous

language could lead to an incorrect or even dangerous acon.

Not for reproduction

SIMPLIPHIPOWER.COM | 805-640-6700 | BSREV202111141140

MODEL NO. 050000, 050001

Step 2: Nofy aected employees

When maintenance is going to be performed, all of the employees that may be aected should be noed. Let them know

the ming of the work, and how long the equipment may be unavailable. If the unavailability of the equipment requires a

change in work processes, be sure they are familiar with the steps to be taken.

Step 3: Shut down equipment properly

Explain the shutdown process in detail. It’s not enough to say something like “disconnect the machine.” To ensure everyone’s

safety and reduce the potenal for damage, the shutdown instrucons should be detailed. Spell out the exact acons to be

taken and the correct sequence for performing those acons.

Step 4: Disconnect all primary energy sources

Although this may seem fairly self-explanatory, once again, it’s important to be very detailed. Whether the primary

energy sources include electricity, steam, water, gas, compressed air, or others, don’t assume that the person performing

maintenance will know the correct procedure to follow. Again, explain exactly what needs to be done.

Step 5: Address all secondary sources

While disconnecng the primary energy sources may remove much of the potenal danger, it’s possible that there sources

of residual energy, such as trapped heat in a thermal system, fumes that may need to be vented, or even tension in a spring

assembly. Idenfy the process that will relieve any remaining pressure or other energy. Also consider other hazards, such as

moving equipment that must be secured before work begins.

Step 6: Verify the lockout

Once you’ve disconnected all primary and secondary sources of energy, aempt to start the equipment to verify that the

lockout has been successful. Before you try to start it, verify that nobody is in a posion where they could be hurt. Assuming

that the procedures have been successful, return all switches and other equipment back to their “o” posions so the

machine won’t start unexpectedly when the energy sources are reconnected. Once you’ve veried the lockout, aach a

lockout or tagout device to the equipment to ensure that it cannot be started without removing the device.

Step 7: Keep it in force during shi changes

The equipment must remain in lockout/tagout condion across shi changes, so that workers arriving at the site are

aware that the equipment is out of service. If individual locks or tags are used, the individual responsible for designang

the lockout/tagout and the individual responsible for it during the next shi must both be present as the locks or tags are

switched.

MODEL NO. 050000, 050001

Step 8: Bring the equipment back online

When the work is done and all tools and other materials have been removed, the machine can be brought back into

operaon. Here again, the procedure should spell out the exact steps that are involved, along with the correct sequence. For

example, you may need to open a parcular machine’s discharge valves before you open the inlet, so any unexpected water

or steam remaining in the lines has a place to go.

Bonus step: Keep procedures up to date

Equipment and operang procedures tend to change over me, and your lockout/tagout program needs to reect those

changes. Somemes, the changes may be so minor that only the people working directly with the equipment are aware of

them. That’s why it’s a good idea to review all your lockout/tagout procedures regularly to verify that they’re sll accurate.

A company with just a small number of machines may be able to check all of them every year, while a larger organizaon

may need to study a certain number or a random sample every year. Another benet of regular review is that it gives you an

opportunity to deploy newer and beer ideas or more accurate descripons.

Notes:

1. These sengs are calculated by mulplying the per-baery value by the number of baeries in the connected baery

bank.

2. Max A Charge refers to the maximum charge rate from the solar PV array. Programming this value to the maximum

value versus the reduced-stress value does not impact the PHI Baery Warranty.

3. If the Auto Generator Start is ulized, the AGS is triggered when the baeries reach this set State of Charge (SoC)

percentage. Once triggered, the generator charges the baeries unl they reach approximately 95% SoC, at which

point the generator turns o. This 95% SoC parameter is not programmable.

4. A refers to the maximum charge rate from the grid or the generator. If the Sol-Ark is connected to both the grid and a

standby generator, the Sol-Ark priorizes the grid as the baeries’ charging source. Programming the A value to the

maximum value versus the reduced-stress value does not impact the PHI Baery Warranty.

5. By default, baery charging from the solar PV array is priorized over generator or grid charging.

6. When the baery has reached the Absorpon voltage setpoint, the Sol-Ark ulizes constant-voltage regulaon to

maintain the baery at the programmed Absorpon voltage. The Absorpon phase lasts unl the baeries charge at 2%

of the programmed Ah size. For example, one PHI 3.8-51.2Vnom baery (rated at 75 Ah), will remain in the Absorpon

charging phase unl the number of Amps used to charge the baery decreases to 1.5 Amps DC (2% of 75Ah).

7. While the PHI Baery does not require an Equalizaon charge, programming Equalizaon to the voltage, frequency and

duraon outlined in the table above ensures that the Sol-Ark’s internal SoC meter re-sets to 100% SoC every 30 days.

8. Smart Loads are no longer powered via solar and/or baeries when the baeries’ SoC level drops below this

programmed Smart Load OFF Ba value.

9. Smart Loads are powered via solar and/or baeries when the baeries’ SoC level exceeds this programmed Smart Load

ON Ba value.

10. The Sol-Ark stops charging the baeries and powering the loads from the AC Coupled solar PV array once the baeries’

SoC level reaches the Smart Load OFF Ba value.

11. The Sol-Ark triggers the AC Coupled solar PV array to produce power (powering the loads and charging the baeries)

when the baeries’ SoC level exceeds this programmed Smart Load ON Ba value.

CAUTION: When PHI baery quanes change, the capacity & charge/discharge current sengs

must be reassessed. Failure to do so will Void the Warranty. Modicaon to original factory sengs

can only be accessed by using installer password.

Grid Setup Sengs

The Sol-Ark’s Grid Setup menu includes many advanced features (refer to Secon 5 of this Guide). Regardless of the features

used, the PHI baery bank should never discharge more than its maximum connuous discharge rate. Furthermore, to maintain

the PHI baeries’ 10,000-cycle level, do not discharge the baery bank to a State of Charge (SoC) level less than 20%. These

details are controlled in the Grid Setup menu’s Limiter tab.

Figure 21 - Limiter Tab in Grid Setup Menu

The power (W) column in Figure 21.0 above dictates the maximum amount of power pulled from the baeries and should be

set to the PHI baery bank’s maximum discharge rate in AC Was. To calculate the connected PHI baery bank’s maximum

discharge Was (AC):

1. Mulply the number of baeries in the bank by the maximum discharge rate (ADC) per baery

• PHI 3.8-51.2Vnom baery max. discharge rate = 37.5 ADC per baery

2. Convert the baery bank’s DC discharge current to DC discharge was.

3. Apply the discharge eciency.

Populate the Ba column to the right of the power (W) column according to the degree to which you wish to discharge the

baery bank. Again, to maintain the PHI baeries at the 10,000-cycle level, do not populate the Ba column with any value less

than 20%.

Grid Sell / Grid-Tied with Baery Backup

A net energy metering agreement with the ulity company is required in order to sell energy from the solar PV array to the grid.

In this mode, the Sol-Ark priorizes powering all loads (on both the essenal loads sub-panel and the main house breaker panel)

from solar PV rst (if available), then (2) grid, (3) generator, and (4) baeries.

In the event of a grid failure, the baeries will power the essenal loads sub-panel only. Take care to size the baery bank;

accordingly, in a grid failure scenario, the Sol-Ark does not limit the baeries’ maximum current output. The maximum power

draw (kW) on the essenal loads sub-panel should not exceed the maximum connuous discharge rate of the PHI baery bank.

Refer to the Discharge Calculaon in Secon 3 of this Guide:

Discharge Example:

• Circuits on the essenal loads sub-panel amount to a maximum potenal power draw of 37.5 Amps

at 240 VAC, or 9 kW

• Sol-Ark-12K inverter DC-to-AC eciency is 96.5%

• PHI 3.8 kWh-51.2Vnom baery has a maximum connuous discharge rate of 1.92 kW

A properly sized PHI baery bank based on the maximum draw of the essenal loads sub-panel has a minimum of 5 baeries,

even in this Grid-Tied with Baery Backup applicaon. Note also that during a grid failure, the essenal loads’ maximum energy

draw (kWh) is also limited by the baery bank’s capacity.

Limited to Home

Checking the Limited power to Home box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu allows for all loads*

(on both the essenal loads sub-panel and the main house breaker panel) to be powered using the connected solar PV and/

or baeries. The Sol-Ark priorizes powering these loads from solar PV rst (if available), then (2) grid, (3) generator, and (4)

baeries. To priorize the baeries’ use over the grid or generator during specic set mes, also use the Time of Use Selling

mode.

*While the Limited to Home mode allows for all loads to be powered using solar PV and/or baeries, the SolArk priorizes

powering loads on the essenal loads sub-panel rst, and loads on the main house breaker panel are oset by solar (and/or

baeries, during Time of Use Selling mode mes) as much as possible. If the loads’ draw exceeds the available power from the

solar PV array and (with Time of Use Selling mode also in play) the baeries have also discharged to their minimum programmed

SoC percentage level, the Sol-Ark will then resort to powering loads using grid power.

CAUTION: In Limited to Home mode, limiter sensors are required to ensure that the home’s main breaker

panel circuits are powered without exporng energy to the grid.

Limited to Load

Checking the Limited power to load box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu discharges the baery

to power the essenal loads sub-panel’s loads. The Limited to Load mode does not allow for any solar or baery energy to

power the main house breaker panel and it does not allow for any solar or baery energy to be exported to the grid.

Figure 23.0 – Limiter Tab in Grid Setup Menu

Time of Use Selling / Energy Arbitrage

Discharge baeries to power circuits during specic set mes. Program these mes to coincide with the ulity company’s peak

pricing mes to avoid high energy charges from the ulity.

Homeowners who have a net energy metering agreement with the ulity company can use both Grid Sell and Time of Use

Selling modes to sell solar PV and baery energy (unl the minimum programmed SoC percentage level) back to the grid

during peak sun-hour mes and then discharge the baeries during programmed mes, usually in the aernoon and evening.

Depending on whether Limited Power to Load or Limited Power to Home is enabled, the baeries will power either the

essenal loads sub-panel only (Limited to Load) or the essenal loads sub-panel and the main house breaker panel (Limited to

Home) during the Time of Use Selling me period. Make sure to size the baery accordingly. (Refer to the Discharge Example in

the Grid Sell / Grid-Tied with Baery Backup secon of this Guide for baery bank sizing when baeries power the essenal

loads sub-panel only. Refer to the Discharge Example in Secon 3 of this Guide for baery bank sizing when the baeries power

both the essenal loads sub-panel and the main house breaker panel.)

Homeowners who do not have a net energy metering agreement use both Limited Power to Home and Time of Use Selling

modes to priorize powering all loads (circuits both on the essenal loads sub-panel and the main house breaker panel) from

the solar and/or baeries during programmed mes. Refer to the Discharge Example in Secon 3 of this Guide for baery bank

sizing when the baeries power both the essenal loads sub-panel and the main house breaker panel.

During Time of Use Selling mes, loads are powered from solar rst (if available), baeries second, and the grid third (if baeries

have discharged to their programmed minimum SoC percentage level).

NOTE: Either the Grid Sell or the Limited Power to Home mode (check the appropriate box in the Grid Setup /

Grid Param menu) must be used in conjuncon with Time of Use Selling.

Make sure the Charge box is unchecked during peak pricing mes so that the baeries do not charge when energy from the

ulity company is most expensive (see Figure 24).

O-Grid

The Sol-Ark automacally operates in O-Grid mode when it does not detect a grid connecon. In an O-Grid system setup, all

the home’s loads are connected to the Sol-Ark’s Load Output (63A double-pole breaker).

Do not use the Sol-Ark’s Grid Sell and Limited to Home modes in an o-grid system setup. Check the Limited Power to Load

box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu to allow for the baeries’ power to discharge to the

connected loads.

Generators

The Sol-Ark’s built-in Auto Generator Start funcons as a 2-wire automac switch.

The Sol-Ark’s Grid Input breaker can be used as the generator’s input breaker. In this scenario, check the General Standard box

and the GEN connect to Grid input box in the Grid Param menu’s Sell Control tab:

MODEL NO. 050000, 050001

Due to the fact that many generators’ output frequency is usually less precise than the grid’s, the frequency parameters in the

Grid Param menu’s Grid Input tab may also need adjustment to accommodate a wider frequency range:

Figure 26.0 – Grid Input Tab in Grid Setup Menu

Homeowners who wish to include a grid connecon, generator, and Smart Load funconality can install a transfer switch

allowing for either grid or generator to connect to the Sol-Ark’s Grid Input. This frees up the SolArk’s Generator Input to be used

as an output for Smart Loads (see the following Smart Loads secon for more details).

In an AC Coupled system setup that includes a generator, using a transfer switch for a grid-or-generator connecon to the Sol-

Ark’s Grid Input also frees up the Sol-Ark Generator Input for connecon to the AC Coupled solar PV array.

If the system includes both a generator and a grid connecon, limiter sensors are required. While smaller generators (less than

10 kW) can be wired to the Sol-Ark’s Generator Input, Sol-Ark recommends wiring larger generators to a whole home transfer

switch instead of using the inverter’s Generator Input.

Smart Load

The Smart Load feature allows the homeowner to run higher power non-essenal appliances (hot water, dehumidier, heat

pump, irrigaon pump, etc.) on solar when excess solar power is available. This setup involves connecng these higher power

non-essenal loads to the Sol-Ark’s Generator Input. To parally protect the baeries against over-discharge, set the Smart

Load O Ba and Smart Load ON Ba parameters to the baeries’ acceptable SoC percentage range while in this mode.

However, note that no programmable parameter exists to regulate the baeries’ over-discharge from a current perspecve.

For example, an o-grid system with home loads totaling a maximum instantaneous power draw of 8 kW might include 5 PHI 3.8

baeries, with a maximum combined connuous power output of 9.6 kW

/ 9.264 kW

. With both the Smart Load and Limited

to Load modes enabled and the Smart Load ON Ba parameter set to 100% SoC, the Sol-Ark will begin powering the Smart

Loads (in addion to all the home loads) when the baeries are at 100% SoC. If the combined power draw exceeds 9.264 kW

AC,

(38.6 Amps at 240V

), the baeries will then be operang beyond their maximum connuous power output capabilies. While

the baeries have a maximum surge discharge capability of 80 Amps DC per baery (20.48 kW

/ 19.76 kW

for the 5-baery

bank), the baeries cannot surge at this power level for more than 10 minutes. A combined load drawing more than 9.264 kW

for more than 10 minutes will very likely result in the baeries’ SoC level reaching the Smart Load OFF Ba parameter, if it is set

to 95%. However, feel free to reach out SimpliPhi Power Technical Support (techsupport@simpliphipower.com) if the Smart Load

feature will be used and baery bank sizing claricaon according to Smart Load-specic loads needs to be claried.

Note that in a grid-connected system that ulizes the Smart Load feature, the Waage value to the right of the Smart Load ON

Ba parameter in the Smart Load menu tab (see Figure 5) represents the minimum power required of the solar PV array before

the Smart Loads are powered. Therefore, that Solar PV Waage value can be added to the baery bank’s maximum output

power rang when comparing maximum available solar and baery power available, against the Smart Load power draw:

Smart Load Draw (kW) ≤ Solar PV (kW) + Baery Bank MAX Output Power (kW).

CAUTION: Smart Loads’ maximum power draw cannot exceed the Generator Input breaker’s

50 Amp / 240VAC rang.
