1.3 – Product Overview

The PHI deep-cycle Lithium Ferro Phosphate (LFP) Baery is opmized with proprietary cell architecture, power electronics,

Baery Management System (BMS), manufacturing materials and processes. This assures the highest grade and quality, longest

cycle-life, greatest eciency and freedom from material impuries, toxicity and hazardous risk. The PHI Baery is modular,

lightweight and scalable. It provides power security and seamless integraon of renewable and tradional sources of energy in

conjuncon with or independent of the grid.

1.3.1 – Baery Management System (BMS)

Each PHI Baery contains circuitry that protects the LFP cells from overcharge, over-discharge and extreme load amperage.

If pre-programmed BMS values 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 re-set the BMS (see Secon 6.0 - Troubleshoong of this Manual)

and re-inialize an inverter/charger. Oen, inverter system sengs will be saved within the inverter memory storage and

will not need to be reset. However, this is not an absolute standard but is common in most inverter/chargers and should be

ancipated if the PHI Baeries go into a state of self-protecon and shut down the ow of electricity. Refer to SimpliPhi’s

Integraon Guides for inverter and/or charge controller sengs (hps://simpliphipower.com/product-documentaon/).

CAUTION: Although each PHI Baery contains an internal BMS with circuitry that protects the PHI Baery

cells from over-charge, over-discharge and extreme load amperage, the PHI Baeries must always be

installed with appropriate inverter and/or charge controller sengs to protect the PHI Baery from open PV

voltage and other high voltage charging sources. Exposure to higher voltage than the PHI baery rang will

destroy the PHI baeries and Void the Warranty.

1.3.2 – Built-In Breaker

PHI baeries with threaded stud connecons (such as baery models PHI 3.8-M) are outed with a hydraulic/magnec

circuit breaker. This breaker increases safety during shipping and installaons and allows the baery to eecvely be turned

“OFF” or “ON.” The breaker works in conjuncon with the baery’s built-in BMS and creates addional safety, eciency and

funconality in the overall power storage system.

Figure 1.0 – PHI 3.8 Circuit Breaker

NOTE: 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 electrical codes and standards and evaluated by cered electricians, licensed

installers, and regional code authories.

2.0 – Safety

For safety reasons, read all instrucons and cauonary markings on the PHI Baeries, and all appropriate secons of this

manual. Failure to follow instrucons provided in the Installaon Manual, Integraon Guides and Warranty will Void the

Warranty.

2.1 – General Safety Instrucons

• Do not operate if the PHI Baery has been damaged in any way during shipping or otherwise.

• To reduce the chance of short-circuits, always use insulated tools when installing or working with PHI baeries or other

electrical equipment.

• Remove personal metal items such as rings, bracelets, necklaces, and watches when working with PHI baeries and electrical

equipment. Wear insulated gloves and rubber shoes.

• 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. For baeries with threaded stud connecons, be sure the built-in

breaker is in the “OFF” posion to minimalize the risk of shock or sparks during the installaon and commissioning of the

system.

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

undersized. Do not operate the PHI Baery in conjuncon with damaged or substandard wiring.

These safety precauons are in addion to the Warnings previously outlined on page 4 of this Manual.

2.2 – Response to Emergency Situaons

As with any baery, if the PHI Baery’s cells are severely damaged due to physical abuse, reverse polarity, high voltage,

unmigated current or other electrical phenomenon incurred outside of Warranted specicaons, it can cause electrolyte

leakage and other failures. The electrolyte can be ignited by an open external ame. However, unlike other lithium ion baeries

with cobalt oxides (e.g. LCO, NCM and NCA), the PHI LFP Baeries’ electrolyte and other material components generate a

limited amount of heat and do not go into a state of thermal runaway with re propagaon. The SimpliPhi UL 1973 Baery

Cercaon veries “No Thermal Runaway” (see MSDS for chemical analyses).

While PHI Baeries do not go into thermal runaway with re propagaon, the following protocol should be followed in the event

that the PHI baeries are subjected to electrical re caused by other system components or failures:

• Ensure that the system is no longer energized, either from the solar array or the grid (main disconnect).

• Separate any external cables from baeries if present (cut if necessary) using insulated tools.

• Wear a respirator or dust mask to avoid inhaling soot/dust.

• Wear insulang and abrasion-resistant gloves (if permeable, over nitrile or similar gloves).

• Move baery debris into non-conducve bins capable of handling the weight.

• Dispose as regulaons require.

MISE EN GARDE: Bien que l’eau puisse être un exncteur naturel acceptable et ecace pour les modèles de

baeries PHI Core Power et Peak Power, l’équipement du Système Equilibré Ulisé conjointement avec les

Baeries PHI peut nécessiter l’ulisaon d’exncteurs spécialisés tels que le FM-200 ou autre systèmes de

suppression de CO2.

CAUTION: While water is an acceptable and eecve exnguishing agent for the PHI Core Power and Peak

Power Baery models, the Balance of System equipment used in conjuncon with the PHI Baeries may

require specialized exnguishers such as FM-200 or CO2 suppression systems.

3.0 – Pre-Installaon

3.1 – PHI Baery Performance

PHI Baeries do not need to be de-rated unless running connuously at more than 90% capacity, at temperatures below 32° F

(0° C), or above 113° F (45° C). To achieve the greatest cycle life of 10,000 cycles, PHI Baeries are typically operated at 80%

maximum Depth of Discharge.

All PHI 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.

3.2 – PHI Baery System Sizing

PHI Baeries are designed to operate at the connuous rangs specied in Table 1.0 – PHI Baery Specicaons. Therefore, a

properly sized PHI Baery bank must be sized to handle both the inverter’s “load rate” as well as the maximum potenal charge

rate from the solar photovoltaic (PV) array. Take care to consider not only the energy (kWh) requirement of the baery bank, but

also all other power-related sizing parameters, as outlined in Secons 3.2.1, 3.2.2 or 3.2.3 and 3.2.4. Failure to do so will Void the

Warranty.

MISE EN GARDE: Un mauvais dimensionnement du groupe de Baeries PHI et non conforme aux secons

suivantes endommagera les Baeries PHI et Annulera la Garane.

CAUTION: PHI Baery bank sizing not in accordance with the following secons will damage the PHI

baeries and Void the Warranty

3.2.1 – Sizing for Maximum Instantaneous Discharge (Load Rate)

The load rate is the amount of power that is discharged from the baery bank to the loads. This may include both alternang

current (AC) and/or direct current (DC) loads. PHI Baery banks are sized so that the baeries’ combined maximum

connuous discharge rate meets or exceeds the load rate.

PHI Baery Bank MAX connuous discharge rate kW DC

≥(Inverter DC Load Rate)+(DC Loads,if any)

Because most loads are AC loads, the load rate is typically represented by the inverter’s AC Power Output rang. Convert

the inverter’s maximum potenal AC power draw to the maximum potenal DC power draw from the baery bank by

factoring in the inverter’s eciency rang.

Inverter DC Load Rate=(Inverter power rang kW AC)÷(Inverter eciency)

Example: An inverter rated at 5 kW AC and 92% eciency potenally draws 5.4 kW DC from the baery bank.

Inverter DC Load Rate=(5 kW AC)÷(0.92)=5.4 kW DC

If the system includes DC Loads, no AC-to-DC conversion is necessary. Calculate the minimum quanty of PHI Baeries

needed to ensure that the baery bank does not over-discharge by dividing the load rate by the MAX Connuous Discharge

Rate per PHI Baery (found in Table 1.0 or on the relevant baery’s specicaon sheet).

(Load Rate)÷(MAX Connuous Discharge Rate per Baery)

=Minimum Baery quanty to prevent overdischarge

Example, connued: Three PHI 3.8 kWh baeries must be paired with an inverter rated at 5 kW AC and 92% eciency to

ensure the PHI Baery bank does not over-discharge to power the loads.

(5.4 kW DC)÷(1.92 kW DC)=2.83 --> round to 3

Refer to the Baery Bank Sizing for Maximum Instantaneous Discharge (Load Rate) tables in Appendix B of this Manual for

a complete list of common baery-based inverters and the minimum quanty of PHI Baeries those inverters need to be

paired with to ensure that the PHI Baery bank does not over-discharge. Over-discharging the PHI Baeries will destroy

them and Void the Warranty.

In the case where the inverter’s AC Power Output rang exceeds the connected loads’ actual power draw (i.e. the inverter is

rated at 5 kW but all loads amount to 3 kW of maximum instantaneous power draw), SimpliPhi sll expects that the proper

addional precauons be made to ensure that the PHI Baery bank is not over-discharged. Failure to do so will destroy

the PHI baeries.

3.2.2 – Sizing for Maximum Instantaneous Charge Rate (DC Coupled)

In a DC Coupled system, the solar PV array output can be migated using charge controllers. However, reducing the solar

array’s power output using charge controller programming implies that the PV array’s output is also reduced for the enre

remainder of the system, including the solar power available for powering loads and for exporng to the grid. Furthermore,

greatly reducing the PV array’s output via the charge controllers eecvely wastes the solar PV array’s power and puts

strain on the charge controllers.

Calculate the minimum quanty of PHI Baeries needed to prevent over-charge from the solar PV array by considering

both the solar array size and the charge controller’s potenal output. Whichever value is less should be used to size the

PHI Baery Bank. If the solar array’s maximum potenal current output is less than the paired charge controller’s Output

Amps rang, then the solar array’s maximum potenal current output can be used to size the PHI Baery bank. If the charge

controller’s Amp rang is less than the solar array’s maximum potenal current output, then the charge controller’s rang is

used to size the PHI Baery bank.

Divide the system’s potenal charging current by the MAX Connuous Charge Rate per PHI Baery (found in Table 1.0 or

on the relevant baery’s specicaon sheet) to calculate the minimum quanty of PHI Baeries needed to ensure that the

solar PV array does not over-charge the baery bank.

Example: Three PHI 3.8 kWh-51.2V

nominal

baeries must be paired with a 4,500-Wa solar PV array wired to an 80 Amp-

rated charge controller. In this case, the 80-Amp charge controller is used to determine the minimum PHI Baery quanty

needed to prevent over-charging from the solar PV.

Was = Amps × Volts

4,500 Wa Solar PV Array = Amps × 48 Volts

= 93.75 Amps = MAX potenal solar PV array output

80 Amps < 93.75 Amps --> 80 Amps

= MAX potenal solar PV array output through the charge controller

(MAX potenal charging current) ÷ (MAX Charge Rate per Baery)

= Minimum Baery quanty to prevent overcharge

(80A) ÷ (37.5A) = 2.13 --> round to 3

Example B: Three PHI 3.8 kWh-51.2Vnominal baeries must be paired with a 3,000-Wa solar PV array wired to a 100

Amp-rated charge controller. In this case, the 3,000-Wa solar array is used to determine the minimum PHI Baery

quanty needed to prevent over-charging from the solar PV.

Was = Amps × Volts

3,000 Wa Solar PV array = Amps × 48 Volts

= 62.5 Amps = MAX potenal solar PV array output

62.5 Amps < 100 Amps --> 62.5 Amps

= MAX potenal solar PV array output through the charge controller

(MAX potenal charging current) ÷ (MAX Charge Rate per Baery)

= Minimum Baery quanty to prevent overcharge

(62.5A) ÷ (37.5A) = 1.66 --> round to 2

Refer to the Baery Bank Sizing for Maximum Instantaneous Charge Rate tables in Appendix B of this Manual for a

complete list of common charge controllers and the minimum quanty of PHI Baeries those controllers need to be paired

with to ensure that the PHI Baery bank does not over-charge (assuming that the charge controllers’ full current output

rang is ulized). Failing to do so will destroy the PHI baeries and Void the Warranty.

3.2.3 – Sizing for Maximum Instantaneous Charge Rate (AC Coupled)

In an AC Coupled system, charge controllers do not regulate the PV solar array’s output, and many baery-based inverters

fail to eecvely regulate the array’s output for baery charging. Therefore, in an AC Coupled system, SimpliPhi assumes

that all the connected PV array’s potenal power output will charge the system’s baeries. Determine the minimum

quanty of PHI Baeries needed to prevent over-charge from the solar PV array by dividing the solar array’s power rang

by the MAX Connuous Charge Rate per PHI Baery (found in Table 1.0 or on the relevant baery’s specicaon sheet).

Example: Four PHI 3.8 kWh-51.2V

nominal

baeries must be paired with 6 kW of AC Coupled solar PV to ensure the PHI

Baery bank does not over-charge from the solar array.

(6 kW)÷(1.92 kW)=3.13 --> round to 4

3.2.4 – Overall Baery System Sizing

Size the PHI baery bank so that the minimum number of baeries in the bank is the greater of the two gures obtained

from the Discharge and Charge calculaons. For example, a system that requires 5 PHI Baeries to ensure that the baery

bank does not over-discharge and 3 PHI Baeries to ensure that the baery bank does not over-charge, should include a

nal minimum quanty of 5 baeries. Failure to do so will destroy the PHI baeries and will Void the Warranty.

Note that this quanty of PHI Baeries is the minimum requirement to prevent over-discharge and over-charge from

an instantaneous power perspecve. The system may need more PHI Baeries in the baery bank in order to meet the

system’s energy requirement (the amount of power the baeries must supply to the loads over me).

• Power cabling for paralleling PHI Baeries is not included. All wire should be an appropriate gauge and construcon

to handle the loads that will be placed upon it. Heavy gauge, high strand copper wire is the industry standard due to its

stability, eciency and overall quality.

• Each PHI Baery’s individual wire runs are typically sized at 4 AWG, according to the 80A built-in breaker.

• Conductor ampacity can be determined using Naonal Electrical Code tables.

• Depending on the electrical code of the local Authority Having Jurisdicon, the PHI Baery leads’ gauge may need to be

sized according to the built-in breaker or according to the PHI Baery’s surge rang.

• Baery cables can be custom ordered to include the 3/8” lugs that t on the PHI Baery’s threaded studs.

• Determine the cable length for the PHI Baery terminal farthest from the common busbar or plate rst.

• Addional cabling or slack that remains with the shorter distance runs can be coiled and secured with Zip Ties.

• Wire length should be kept as short as praccal.

• Posive wire runs should be separated from negave wire runs in separate conduit.

• Energy supplied by the PHI Baery is reduced as electrical current moves through wire. For lengths of baery cable

greater than ~10 feet (3 meters), ensure that the voltage drop is no greater than 3%.

• To take full advantage of the combined PHI Baery bank’s surge rang, the DC busbars or plates that the individual PHI

Baeries are wired to should be rated to match the PHI Baery bank’s total surge rang.

starng voltage requirement, then the baery will need to be charged using a plug-in / external charger. SimpliPhi’s baeries

have a very low self-discharge rate and typically do not require ancillary charging. If the PHI Baery’s voltage has dropped due to

over-discharge, try the steps outlined in Secon 6.0 – Troubleshoong prior to using ancillary charging equipment.

MISE EN GARDE: Uniquement uliser un chargeur LFP approuvé par SimpliPhi si une charge auxiliaire est

nécessaire avant l’installaon, une mise à l’essai ou un dépannage. Ne pas uliser un chargeur LFP approuvé

par Simpliphi endommagera les Baeries PHI et Annulera la Garane. Voir l’Annexe C pour plus de détails sur

les chargeurs approuvés.

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 Baeries

and Void the Warranty. See Appendix C for more details on approved chargers.

CAUTION: Do not aempt to loosen the large brass nut at the base of the terminals; doing so will damage the

PHI baery and Void the Warranty.

CAUTION: All SimpliPhi Power Core Power and Peak Power products are designed to work exclusively in

parallel. Never connect in series to achieve higher voltages. Wiring in series will destroy the PHI baeries

and Void the Warranty.

Verify polarity at all connecons before energizing system. Reverse polarity at the PHI Baery terminals will

destroy the PHI baeries and Void the Warranty.

1. Before installing the PHI Baery, inspect the baery for any signs of damage. Do not install or operate the baery if it has

been damaged during shipping.

2. Prepare the baery module for installaon by removing its plasc terminal covers, 11/16” stainless steel hex nuts and 3/8”

lock washers from the baery terminals and set aside.

3. Before installing the PHI Baery, test its voltage by turning its built-in breaker to the ON (I) posion.

4. Measure the PHI Baery’s voltage with a mulmeter. Baeries typically ship at 20% State of Charge, which correlates with

~50.2 VDC.

5. When installing more the one PHI Baery, check that the baeries’ voltage readings are similar. Baeries with a voltage

variance greater than 1 Volt DC should be isolated and charged separately.

6. Aer tesng the PHI Baery’s voltage, turn the baery’s built-in circuit breaker back to the OFF (0) posion.

7. Wire the PHI Baery bank with all the included PHI Baeries’ built-in breakers in the OFF (0) posion.

CAUTION: Remember that charging the baeries in sub-freezing condions will Void the Warranty.

8. Conrm all loads are turned OFF. Disconnect the inverter’s AC Output breaker or turn o the breaker at the top of your

loads’ breaker panel.

9. The main DC disconnect in the inverter’s power panel should sll be in the OFF posion.

10. Turn all baery circuit breaker switches to the ON (I) posion.

11. Turn the main DC disconnect in the inverter’s power panel ON.

12. At this point, the inverter may come on automacally in standby mode, or the inverter might need to be manually turned on.

13. Program the Balance of System Equipment (inverter and/or charge controller) to SimpliPhi’s sengs, as specied in the

relevant Integraon Guide (hps://simpliphipower.com/product-documentaon/) and generally outlined in Secon 5.0 –

Programming of this Manual.

14. Charge the baeries fully. When rst commissioning the baery system, the baeries must be charged fully before

connecng any loads. Neglecng to charge the baeries fully when rst commissioning the baery system will Void the

Warranty.

15. Baery charging may be accomplished via the inverter/charger using an AC power source such as the grid or a generator, or

via a charge controller using power from a connected solar PV array.

16. The baeries will bulk charge to 56 VDC, will Absorb for 6 minutes (0.1 hours), and will then rest at approximately 53.3

VDC. At this point in the charging cycle, these voltages (53.3V / 26.7V / 13.3v) are considered 100% SOC.

17. Once the baeries are fully charged, turn on the inverter’s AC Output breaker and/or the breaker at the top of your loads’

breaker panel.

4.8 – Baery Bank Expansion

New SimpliPhi Baeries that are added to an exisng SimpliPhi baery bank must be of the same nameplate voltage and form

factor. If higher capacity PHI baeries are added, such as PHI 3.8-M to a bank of PHI 3.5, the baery bank’s total energy capacity

for system sizing calculaons is the sum of the original baery capacity rang (3.5) mulplied by the new total number of PHI

baeries. Therefore, the capacity rang of the original 3.5 PHI baeries determines the capacity rang for the newer PHI 3.8-M

baery once installed with the original baery bank. For example, a baery bank composed of two PHI 3.5 baeries and one

PHI 3.8-M baery has a total energy storage capacity for system sizing calculaons of 10.5 kWh for the bank (3 X 3.5 kWh= 10.5

kWh total). In addion, the Warranty for the new, addional PHI 3.8-M baery adopts the Warranty and Warranty period for

the original bank of PHI 3.5 baeries.

Consult SimpliPhi Power Technical Support if you wish to expand a SimpliPhi baery bank.

In addion to adhering to all other Installaon Manual instrucons, refer to the following guidelines when expanding upon an

exisng SimpliPhi baery bank:

1. Charge the exisng baery bank (“Bank A”) according to normal charging procedure (48V PHI baeries charge to 56V and

“rest” at approximately 52.5 - 53.5V aer being taken o a charge).

2. Disconnect Bank A from the system, by either

A. Disconnecng all baery cables leading from Bank A’s baeries to the baery combiner box, panelboard, or inverter’s

power panel, OR

B. Turning o the 80A breakers included in each of Bank A’s baeries

3. Connect the addional baeries (Bank B) to the system, following all wiring instrucons and torque specicaons outlined

in previous secons of segment 4.0 in this manual.

4. Modify the sengs in the system’s inverter/charger(s) or charge controller(s), whichever device will be used to inially

charge Bank B.

A. Adjust the charge rate in accordance with the number of baeries in Bank B

5. Charge Bank B fully, making sure all loads are disconnected at the me of inial charge

6. Wire all Bank A baeries and Bank B baeries in parallel, adhering to the wiring methods outlined in Secon 4.3 above.

A. Ensure that DC Posive common bus and DC Negave common bus rangs are appropriate for the new larger quanty

of baeries in the bank.

7. Reprogram all inverter/charger and/or charge controller equipment for the new larger baery bank capacity.

A. New charging current parameters for the expanded bank should be appropriate for the oldest included PHI baery

model. For example, a baery bank composed of one PHI 3.5 baery with a maximum connuous charge rate of

34 Amps DC and one PHI 3.8-M baery with a maximum connuous charge rate of 37.5 Amps DC has a combined

maximum connuous charge rate of 68 Amps DC (not 71.5 Amps DC).

CAUTION: Before commissioning the system, the appropriate controller and inverter sengs must be

programmed per the manufacturer’s recommendaons. Consult the manufacturer’s manuals and/or the

Integraon Guides listed on SimpliPhi’s Product Documentaon web page (Schneider, Magnum, Outback,

etc.). Failing to do so will damage the PHI baeries and will Void the Warranty. The following Charge

Controller Integraon tables are for general reference only.

6.0 – Troubleshoong

If your PHI Baery bank is reaching its Low Baery Cut Out voltage (LBCO), load disconnects or load shedding set points may

need to be adjusted.

The PHI baeries are reading extremely low or no voltage:

Programmed sengs in the PHI Baery’s accompanying Balance of System equipment should prevent the PHI Baery’s internal

BMS from reaching its low voltage seng. However, in the instance that the PHI Baery’s BMS has turned the PHI baery o,

the baery will read low or no voltage, and the following steps should be taken to re-set the BMS:

1. Turn o each of the built-in breakers in all of the PHI Baeries in the baery bank*.

2. Turn o the main DC disconnect located in the inverter’s power panel, between the baery bank and the inverter.

3. Turn o the main breaker at the top of the inverter’s AC distribuon panel or sub-panel.

4. Wait 5 minutes, for the BMS in each baery to re-set itself.

5. Use a mul meter to take voltage measurements of each PHI baery in the baery bank, to make sure the voltage increased

to the minimum voltage necessary for the inverter to turn on.

To measure a single baery’s voltage within a baery bank, only the baery being measured has its built-in breaker in the

ON (I) posion; all other baeries in the bank must have their built-in breakers OFF (0).

6. Turn on each of the built-in breakers in all of the PHI Baeries in the baery bank.

7. Turn on the main DC disconnect located in the inverter’s power panel.

MODEL NO. 052000

8. Check that all parameters in the Balance of System equipment are programmed according to the relevant SimpliPhi

Integraon Guide. Failure to do so will damage the PHI baeries and Void the Warranty.

9. To charge the baeries quickly, SimpliPhi recommends using an AC power source to immediately charge the PHI baery

bank via the inverter’s charger. However, the PHI baeries will not incur any damage if they are charged using a connected

solar PV array via the charge controller. The important aspect of this step is that the baeries re-charge as soon as the BMS

has re-set.

10. Turn on the inverter’s AC Input breaker and turn on the inverter.

11. The inverter should automacally self-iniate a baery charge. However, a Force Charge may need to be iniated in the

inverter.

Appendix A – PHI Baery Safety & Green Aributes,

Cercaons

This Appendix secon covers the PHI Baery safety aributes and cercaons, such as the lack of thermal runaway with

re propagaon, o-gassing, UN DOT cercaon and UL compliance and cercaon. It also covers the PHI Baery’s green

aributes – from products to materials to disposal, as well as relevant environmental and ecological consideraons.

A.1 – Safety Aributes and Cercaons

A.1.1 – Intrinsically Safe Operaon and Installaon

The PHI Lithium Ferrous Phosphate (LFP) baery cell component is made with an intrinsically safe cathode material (iron

phosphate). This creates a strong molecular bond, which withstands extreme condions, prolongs cycle life, and maintains

integrity with lile or no maintenance over extended periods of me. There is virtually no danger of Thermal Runaway with

re propagaon, as there may be with Lead Acid, NiCd, and Lithium Cobalt type baeries (NCA, NMC, LCO). No venng or

cooling is required. No precauons or special structural consideraons are necessary when installing PHI Baeries.

A.1.2 – No Safety Hazards due to O-Gassing, Exposure to Acids, Thermal Runaway

PHI Baeries do not vent dangerous gasses during normal operaon, such as hydrogen and oxygen, because chemicals

contained in Lithium Ferro Phosphate cells’ electrolyte do not electrolyze to any appreciable extent within the PHI Baery’s

operang voltage range. In contrast, lead acid baeries which contain water and sulfuric acid experience signicant

electrolysis into H2 and O2 during normal operaon. There are no dangers of exposure to sulfuric acid because PHI

Baeries do not have causc electrolytes. Thermal runaway with re propagaon is not an issue with PHI products due to

the basic nature of Lithium Ferro Phosphate cell chemistry ulized in all our power storage products.

A.1.3 – PHI Baery Control and Protecve Circuitry

SimpliPhi Power Inc. ulizes balancing, voltage regulaon, thermal and current controls, as well as other protecve

measures, in its PHI Baery Management System (BMS). This protecve circuitry is embedded in the architecture of each

PHI Baery.

A.1.4 – UN DOT Cered Cells

The Lithium Ferrous Phosphate (LFP) cells are independently cered to withstand the UN DOT 38.3 tesng guidelines

with no special circuitry added. These tests include short circuit, over-voltage, overcharging, extreme temperature, high

altudes, shock and extreme vibraon tesng.

A.1.5 – UL Compliance

The Lithium Ferrous Phosphate cells within the PHI Baeries fully comply with the safety tesng parameters of UL 1642.

A.1.6 – RoHS Compliant

SimpliPhi Power 3.8 Baeries are RoHS compliant. Any RoHS compliant component is tested for the presence of Lead

(Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated

diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight

at raw homogeneous materials levels. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when

calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury

and the mercury must not have been intenonally added to the component. In the EU, some military and medical equipment

are exempt from RoHS compliance.

A.2 – Green Aributes, Environmental & Ecological Consideraons

A.2.1 – Materials

The primary materials (lithium, iron, phosphate) that make up PHI Baeries are environmentally benign and pose very few

pollung or environmentally degrading by-products in the harvesng and renement processes. This is especially true when

compared to those of lead acid, NMC, NCA, LCO, NiCad, and NiMH baeries.

MODEL NO. 052000

A.2.3 – Operaon

There is no need for maintenance, such as adding water or chemicals, nor is there corrosion of terminals or containment

facilies, or dispersion of fumes as with other baery types. Once installed, PHI Baeries are maintenance free as long as all

the Installaon Manual, Integraon Guidelines and Warranty requirements are adhered to.

A.2.4 – Life Cycles

PHI Baeries are designed for thousands of cycles while maintaining 80 percent or more of their inial capacity. To achieve

this, it is crical to follow the operang condions outlined in the Warranty.

A.2.5 – Disposal

PHI products are non-hazardous, may be disposed of without damage to the ecosystem, and returned to the earth, while

easily recombining with the elements without harmful by-products. The outer casing and brackets contain steel, aluminum,

copper, cardboard, and recyclable plasc. Lithium Ferrous Phosphate (LFP) materials can also be recycled through

established baery centers if desired.

A.2.6 – Lithium Ferrous Phosphate Baeries and the Environment

As the use of this baery chemistry in larger baeries becomes more common, quesons of sustainability and

environmental impact inevitably arise. Of the lithium ferrous phosphate chemistries being considered for large format

baeries, SimpliPhi Power believes that baeries based on our proprietary lithium ferrous phosphate chemistry and

circuitry oer a clear advantage, not only over alternate Li-ion chemistries (lithium cobalt oxide), but all baery chemistries

that are currently commercially available. This belief is based on the minimal environmental impact associated with the

manufacturing of PHI Baeries, the extended cycle life and the signicantly smaller end-of-life footprint that results from

the use of PHI Baeries.

A.3 – Summary

The Lithium Ferrous Phosphate (LFP) cells ulized throughout the enre PHI and LibertyPak product lines are classied as

non-hazardous by OSHA and WHMIS. They are non-toxic, unlike NMC, NCA, LCO, NiMH, NiCad or Lead Acid types of baeries

(including AGM). The PHI Baeries contain the least amount of toxic metals and are the most eco-friendly of all common

baery types. Lithium easily combines into harmless compounds when disposed of. The PHI Baeries are the least pollung

rechargeable baeries on the market today – no fumes, leaking, or gas discharge and no chemicals or acids to worry about.

Appendix C – PHI Approved External Chargers

This Appendix secon covers the PHI Baery’s approved external / plug-in chargers.

Typically, ancillary charging of SimpliPhi’s baeries is not required, and charging using any of the charge controllers and/

or inverter/chargers listed in the “Integraon Guides” secon of the SimpliPhi web site’s Product Documentaon page is

acceptable. However, ancillary charging may be necessary in the following situaons:

1. No charge controller or inverter/charger is available

2. Increasing the baery’s State of Charge (SoC) aer an extended storage period and prior to installaon

3. For recharge purposes when the baery’s voltage is below the minimum required voltage for charge controller and/or

inverter/charger equipment to turn on

If the above listed chargers are unavailable or undeliverable to your specic locaon, SimpliPhi also approves of Iota

Engineering’s baery chargers (link here) to increase the PHI baery’s voltage. These chargers should only be used in order to

increase baery voltage enough to regain system operability; these chargers should not be used to regularly and fully charge the

PHI baery.
