2.2 Integrating Batteries
A. Sol-Ark 60K-3P-480V must be OFF while you connect the batteries.
B. Be sure that the external battery disconnect is OFF or arcing may occur. If your battery bank does not have a built-in disconnect,
maintain the necessary safety measures when handling the connections.
C. The 60K-3P-480V reaches a max battery charge/discharge of 50A per terminal for a total max of 100A if using both sets of battery
terminals. If only one set of terminals is used, the battery charge/discharge will be limited to 50A.
Sol-Ark 60K-3P-480V is a HIGH VOLTAGE BATTERY system. You MUST NOT exceed 800V
DC
as shown below. The HV battery must
stay within the 160V
DC
- 700V
DC
operating voltage range. DO NOT connect to any battery whose max voltage that exceeds this limit.
a) Single HV battery
b) Bank of multiple HV batteries
Figure 4: Battey Wiring Output
The Sol-Ark inverter has two input battery terminals for single or dual battery connections. To wire a battery to the inverter, lift the actuation
levers and insert the 6-4 AWG battery conductor fully into the terminal. DO NOT force open the battery actuation levers more than 90°.
DANGER: Reverse Polarity
DO NOT reverse the battery input wires, the system will be damaged, and the warranty voided.

Sol-Ark 60K Installation Guide | SK140-0019 Rev 4 11
Multi-Terminal Installation
The two battery input terminals of the 60K-3P-480V can be configured for parallel battery stacks in settings screens. If the charge/discharge
rate of 100A is needed, the battery must be connected to both input terminals. If connecting more than one battery to a single inverter
input terminal, you must use an external busbar or combiner to combine batteries positive and negative outputs before connecting to the
inverter terminals.
a. Single battery
B. Parallel battery bank
c. Dual battery bank
NOTE: If a single battery is capable of charge/discharge currents above 50A, connect the battery to both
input terminals. Otherwise, the charge and discharge rate will be limited to 50A max. Only connect
batteries of the same model to the terminals
Parallelled Battery Installations
A. ALL systems MUST be connected to their own battery bank, and the battery banks must be the same size.
B. DO NOT parallel batteries between inverters.

2.3 Battery Communications
The Sol-Ark 60K-3P-480V inverter can establish closed-loop battery communication through one or two separate RJ-45 ports labeled
“BMS1” and “BMS2”. Communication with battery BMS will depend on the wiring of the battery bank and the wiring to the Sol-Ark inverter.
The following two methods show how communications can be established:
Single Battery Bank Communication
Configure and wire the HV batteries so that there is one battery bank with a single communication source. Closed-loop communication is
established by connecting the com cable to the BMS1” port of the Sol-Ark inverter.
🗹 Parallel Bat1&Bat2” setting on the Batt setup menu MUST be enabled and batteries must be connected in parallel on the DC side.
See previous section “Multi-Terminal Installation” for detailed wiring of multi-terminal, single battery bank installation.
Figure 6: Single battery bank communication
Parallel bat1&bat2: Must be checked when using both battery inputs for the same battery bank. When enabled, the inverter will expect a
single battery communication source.
background
Sol-Ark 60K Installation Guide | SK140-0019 Rev 4 13
Separate Battery Banks Communications
Configure and wire the HV batteries so that there are two battery banks, each with their separate communication source. Closed-loop

E. Strings in parallel on the same MPPT must have the same designed open-circuit voltage (Voc), otherwise the system will be
limited to the lowest string voltage.
PV1 A/B must have the same Voc.
If the solar panels are oriented in different directions and connected in the same MPPT, there will be a loss in PV efficiency.
F. Per NEC Art 690.43, exposed non-current-carrying metal parts of PV module frames, electrical equipment, and conductor
enclosures of PV systems shall be connected to an equipment grounding conductor. All grounding conductors and grounding
electrodes should be installed according to NEC Art 690.47 or as required by the AHJ.
G. For ground mounted arrays, Sol-Ark recommends installing an auxiliary grounding electrode placed near the array to ensure
optimal earth-to-ground resistance of the grounding system. This auxiliary electrode would need to follow the requirements of
NEC Art. 250.54.
NOTE: 60K-3P-480V has 4 independent MPPTs that support up to 2 PV strings each. The MPPTs can
handle a maximum V

AC Coupling
The Sol-Ark 60K-3P-480V supports the addition of grid-tied solar inverters, this allows the systems total solar power input to be expanded
by coupling 3Φ micro or string inverters into the “GEN” terminals of the inverter.
An entirely AC-coupled solar system is not recommended as power control and monitoring is limited but is supported. Having DC-coupled
modules, or a combination of DC-coupled modules and AC-coupled inverters is always preferred. AC-coupled inverters used in this
application need to be either UL 1741SA or SB certified. This certification confirms the inverters’ ability to disconnect from the grid based
on frequency and ensures that the Sol-Ark will safely be able to frequency shift to control the AC coupled production.
In off-grid systems or during grid-forming operation, the 60K-3P-480V uses frequency shifting to curtail and shutdown AC-coupled
inverters when the battery is full, allowing AC-coupled solar to produce power in an outage scenario. When the 60K-3P-480V is connected
to the grid any AC-coupled inverters connected will always sell all excess solar power back to the grid. Selecting “Limited to Load” will
NOT limit production when AC coupled.
Maximum allowed AC coupling input: 60,000W
AC
AC Coupling on the GRID Side
Installing AC coupled inverters upstream of the GRID port of the 60K-3P-480V, such as with a load or supply side connection, is supported
for grid connected systems but has some notable limitations when using the inverter for backup or grid-forming mode:
Does NOT allow the usage of grid-tied inverter production during grid outages to charge batteries or power loads.
Does NOT allow monitoring of PV production in inverter and MySolArk monitoring.
AC Coupling on the GEN Terminal
AC Coupling via the GEN Terminal is the preferred method for integrating AC-coupled solar on the 60K-3P-480V. This method offers
several key advantages:
Allows the usage of grid-tied inverter production during grid outages.
Allows the integration of grid-tie inverters in off-grid systems.
Using the GEN terminal also allows for comprehensive monitoring of solar production, giving users valuable insights into the system's
performance. See Section 3.4 - AC Coupling Settings for details on programming the 60K-3P-480V for this mode of operation.
AC Coupling on the LOAD Terminal
NOTICE: Sol-Ark does not support AC-coupling on the LOAD terminal with the 60K-3P-480V.

3. Increase the voltage range of operation:
a. Increase “Grid Volt High” to 528V.
b. Decrease “Grid Volt Low” to 432V.
c. Replicate changes for the Normal Connect settings.
2.6 Grid Peak Shaving
1. To use Peak-Shaving on a generator, the equipment MUST be connected to the
“GRID” terminal of the inverter.
2. Peak-Shaving helps reduce grid consumption during peak demand by utilizing battery
backup power. It can also be used to prevent generator overload above a specified
power threshold.
3. Install the CT sensors on grid / generator lines L1, L2, L3. The arrows on the CTs MUST
point toward the inverter.
4. The Sol-Ark supplies power from the batteries whenever the “Power” threshold is met.
5. This mode will automatically adjust the “Grid Charge” amperage (A) to avoid
generator overloads during battery charging.
6. Grid Peak-Shaving will automatically enable “Time of Use” and MUST be configured.

2.7 Automatic Generator Start
1. 🗹 Gen Charge” is used when the generator is connected to the “GEN” terminal.
a. “Start V” or “Start %” is the set-point/condition that must be fulfilled to automatically start the generator.
b. To charge from the “GEN” source, “🗹 Gen Charge” must be enabled.
c. Batteries will charge from a generator until the battery bank accepts 5% of its programmed capacity in Amperes (A). This
is equivalent to around 95% of the state of charge (SOC).
2. 🗹 Grid Charge” is used to charge the battery from the “GRID” source (grid or a generator).
a. “Start V” or “Start %” is the set-point/condition that must be fulfilled to start the battery charge from the “GRID” source. This
will auto-start a generator as well.
b. To charge the battery from the “GRID” source, “🗹 Grid Charge” must be selected: Battery Setup Charge.
c. From utility grid: the batteries will be charged to 100% SOC.
d. From generator: the batteries will charge until the battery bank accepts 5% of its rated capacity in Amperes (A). This is
equivalent to around 95% SOC.
Gen Charge / Grid Charge “A”
“A” is how many amps (DC) are supplied to the battery from the GRID or GEN source. Adjusting and limiting the Gen or Grid “A” value
will ensure that small generators are not overloaded when charging the battery bank.
If connecting more than one HV battery in parallel to the Sol-Ark inverter, divide the Gen or Grid “A” value by the # of batteries to estimate
the current (A) flowing to each HV battery.
NOTE: If “Time of Use” (TOU) is enabled, a time to charge from that GRID or GEN source MUST be
designated. “🗹 Charge” must be checked on desired time intervals, otherwise the generator will not
start automatically even if the Start V or Start % condition has been met.

2.9 Connecting Current Transformers (CT Sensors)
The CT sensors (or limit sensors) enhance system capabilities by enabling the use of the system work modes known as “Limited Power to
Home” (Meter Zero) and “Grid Peak-Shaving”. The CTs will measure and calculate total load demand which the Sol-Ark 60K-3P-480V will
then use to accurately supply and offset all existing loads (Meter Zero).
Figure 14: CT Sensors
1. Installing CT Sensors
DANGER: RISK OF ELECTRIC SHOCK
Before installing CT sensors around current-carrying conductors, you MUST:
1. Connect the CT outputs to the designated inverter input terminals, OR
2. Short the CT output wires using a CT shorting block
This step is crucial to prevent the generation of dangerously high voltages in the CT secondary
winding when this circuit is open and current is flowing through the primary.
To begin, install sensors on incoming electrical service wires (L1, L2, L3).
The marked arrows on the CT sensors must point towards the inverter.
To ensure proper fit, check incoming wire diameters (grid or generator). If the sensors are too small, larger CTs can be purchased.
“Limited Power to Home” (Meter Zero) and “Grid Peak Shaving” require CT sensors.
See section 3.5, “Limiter” for more information about the different work modes.
See section 7, “Wiring diagrams” for more information on CT installation.
Figure 15 Overview of CT Placement
2. CT Sensor Size
The 60K-3P-480V inverter includes three 300A CT sensors with a 1.85x2 (47x52mm) opening.
The inverter should be programmed to use a ratio of 6000:1 if using the included 300A CT’s.

Connect CT2 of line L2 to pins 3+ (white) & 4- (black) of CN1 pin board.
Connect CT3 of line L3 to pins 5+ (white) & 6- (black) of CN1 pin board.
Keep the wires twisted throughout the run and only separate 1in (25mm) when making the termination at the inverter.
If the wires need to be extended, use a minimum of 16AWG twisted pair shielded cable to make the extension.
o Max CT extension length is 50ft using 14AWG twisted pair cable, for longer runs contact Sol-Ark for design assistance.
Figure 16: CT to Inverter Wiring
CT Sensors with Parallel Inverters
Only one set of CT sensors need to be wired to the designated “Master” inverter.
CT sensors are required for multi-inverter systems.
Selecting Current Transformers for Larger Services
If the included CTs are not suitable for the installation service larger CTs can be purchased separately. When selecting the CT the primary
rating should be sized as close to the service size of the panel as practical. This ensures accurate measurements and proper system
operation. For example, for a site with a 400A service panel, choose a CT with a 400A primary rating or the next available higher rating.
Selecting a CT with a primary rating significantly higher than the service size may result in reduced accuracy for lower current
measurements.

Programming CT Ratios
To program the inverter with the correct CT ratio, begin by going to the Basic Setup Advanced screen of the inverter, as shown in
Fig. 14. The correct CT ratio can be calculated by dividing the primary side current by the secondary side output current, the resulting
number should be multiplied by 100 before entering it into the CT Ratio setting on the inverter.
Example: 800A primary with a 5A secondary output, 800A / 5A = 160 or 16,000 ratio on the inverter.
NOTE: The maximum value that can be programmed on the inverter is 40,000
Figure 17: Settings Screen of the inverter for modifying CT Ratio
5. Automatic CT Limit Sensors Configuration
This function REQUIRES batteries to auto detect and auto correct CT orientation. AC coupled inverters need to be OFF during the
detection test. If this test is done with connected AC-coupled systems, a factory reset of the Sol-Ark must be performed. Install the CT
sensor as described previously. A battery connection and grid power are required before starting the automatic configuration.
Basic Setup Advanced 🗹 Auto detect Home Limit Sensors
Wait at least 10 to 15 seconds while the inverter performs the test. The inverter will alternate the current distribution in all lines,
determining the correct orientation of the sensor.
Operational Notes
On “Limited power to Home” mode (no Grid Sell), HM values will read close to zero (0). Keep in mind that many sensors
can have a 1-3% error.
To avoid selling power to the utility use “Zero Export Power” equal to or greater than 20W.
Buying power from the grid will display positive (+) HM values, while selling to the grid displays negative (-) HM values

2.10 PV Rapid Shutdown
Rapid shutdown is a critical safety feature required by the National Electrical Code (NEC) for solar photovoltaic systems located on
buildings. It allows first responders to quickly de-energize the DC and AC conductors of a solar system in an emergency.
The 60K-3P-480V inverter implements rapid shutdown through the use of the emergency stop pins located in the CN2 wiring area. Pins 7/8
are a normally open (NO) contact that will trigger rapid shutdown (RSD) when closed. Closing this contact using an external e-stop button
(not included) will disable all power flows from the inverter, including the LOAD output when off-grid. When this same button is wired to
the RSD device power supply it will also trigger module level shutdown at the solar module using module level shutdown or optimizer
modules.
Connect an emergency stop button connects to CN2, (B, B) pins 9 & 10 of the Sol-Ark.
Rapid Shutdown Transmitters placed inside the user area of the Sol-Ark can cause interference.
On parallel inverter installations, the emergency stop button must be wired to the designated “Master” inverter.
CAUTION: The 12Vdc power supply on Pins 7 & 8 of the 60K-3P-480V is not rated to power
Rapid Shutdown Transmitters. DO NOT CONNECT any device to these terminals
Third-party rapid shutdown transmitters should be powered by the 60K-3P-480V through an external power supply connected to the
“LOAD” output, as illustrated in Fig 15. Pressing the e-stop button will disconnect all AC outputs, cutting power to the “LOAD” connected
service panel which will initiate rapid shutdown.

3.5 Limiter
Limiter
The Sol-Ark 60K-3P-480V inverter will simultaneously utilize different available power sources to satisfy load demand in the electrical
service panels (essential loads panel / main service panel). The following work modes allow the user to determine how power is generated
and utilized.
Grid Sell
Grid Sell: The inverter will produce as much power as it has available from PV array according to the programming. The maximum power
that can be generated from DC coupled arrays and sold to the grid is 60,000W.
Description
a. This mode allows the inverter to sell back power generated from the solar arrays up to a programmable limit.
b. The inverter will only measure loads connected to the “LOAD” terminal.
c. The inverter will measure all power in/out of the “GRID” terminal as grid either consumption (+) or grid sell back (-).

background
Sol-Ark 60K Installation Guide | SK140-0019 Rev 4 35
Limited Power to Home
NOTE: This operating mode REQUIRES batteries.
Limited Power to Home (Meter Zero): This mode limits the energy produced by the inverter to satisfy the total demand (essential loads
panel + main service panel). In this mode, the inverter delivers power to the “LOAD” terminal (essential loads panel) + the “GRID” terminal
(main service panel). CT sensors MUST be installed. These sensors measure load consumption in the main service panel to offset total load
demand and prevent selling to the utility. This system work mode is useful for users that don’t have a permit to sell back. See section 2.9
“Limit Sensors” for proper external CT installation.
General description
a. Power is delivered to all home loads without selling excess solar to the grid. This mode is suitable for systems where selling to the
utility grid is not allowed.
b. External CT sensors are required for proper operation.
c. Monitored loads will be the addition of the main service panel + essential loads panel.
d. Energy Priority: 1. Solar PV Power | 2. Grid Power | 3. Batteries | 4. Generator
Figure 27: Operating Mode Diagram - Limited Power to Home
Limited Power to Home + Grid Sell: This mode will NOT limit solar production to home demand. In this mode, the inverter delivers power
to the “LOAD” terminal (essential loads panel) + excess power to the “GRID” terminal (main service panel AND grid). The Sol-Ark will
monitor grid sell and load consumption simultaneously (with +/ - 3% error from CT sensors). The CT sensors MUST be installed. The
inverter will sell excess solar power up to a programmable limit. See section 2.9 “Limit Sensors” for proper external CT placement.

NOTE: This operating mode REQUIRES batteries
Limited Power to Load: This mode limits the solar production to cover “LOAD” demand (essential loads panel) exclusively. In this mode,
the system disregards loads in the main service panel and will not deliver power to the “GRID” terminal.
Description
a. Power is limited to the “LOAD” demand. It will NOT produce more power than necessary.
b. Power will NOT be delivered to the “GRID” terminal (NO grid sell).
c. Monitored loads will be exclusive to the essential loads panel.
d. This mode is recommended for off-grid applications.
e. Energy Priority: 1. Solar PV Power | 2. Grid Power | 3. Batteries | 4. Generator

Time of Use
Time Of Use (TOU): This mode combined with “Limited Power to Home” or “Limited Power to Load” allows the use of battery backup
power to reduce consumption from the grid during specific time intervals. Battery power will cover load demand at a programmable
power rate “Power(W)” down to a programmable “Batt (V / %SOC)”. You can configure six different time intervals over a 24-hour period
to cover a wide range of battery discharge or charge behaviors.
Description
a. Uses battery power to reduce the power consumption during user defined time intervals.
b. Power (W) dictates the rate at which the battery discharges to assist with load demand.
c. Batt (V or %) dictates the lower discharge limit or upper charge limit.
d. Energy Priority: 1. Solar PV Power | 2. Batteries (down to programmed discharge V or %) | 3. Grid Power | 4. Generator.
Figure 31: Operating Mode Diagram - Limited Power to Home + TOU
Time: Programable time intervals over a 24h period. All time slots MUST follow chronological order and must be programmed.
Power(W): Sets the maximum discharge rate of the battery during the corresponding time slot.
Batt: V or % used to specify a lower discharge limit or upper charge limit whenever 🗹 Charge” is enabled. Grid-tied systems will not
allow TOU to discharge lower than “Low Batt V/%”. Off-grid systems allow TOU discharge down to “Shutdown V/%”.
🗹 Charge: During the hours selected, it is allowed to charge batteries from an external AC source up to a programmed voltage or %. If the
external AC power source is a generator, the “Start V” or “Start %” condition must be fulfilled first. If available, the solar array will always
charge the batteries at 100% regardless of 🗹 Charge” in TOU.
🗹 Sell: Allows batteries to discharge and sell power to the grid at the programable “Power(W)” rate. 🗹 Grid Sell” MUST be enabled.
NOTE: Do not enable “Charge” and “Sell” at the same time
Other
GEN Connect to Grid Input: Specifies when a generator is connected to the “GRID” terminal.
Zero Export Power: Minimum power imported from the grid. Helps avoid selling back by ensuring constant grid consumption. The value
can be set between 1 100W (recommended 20W).
Batt First: Default and recommended option. Sets the solar power priority of the system to charge batteries first. Do NOT change
unless instructed by Sol-Ark technical support.

Installation Tips
Off-Grid Installation
1. Limit sensors (CTs) are not required for completely off-grid installations unless using “Grid Peak Shaving” for a generator connected
to the “GRID” terminal.
2. Connecting generators to the “GRID” terminal is recommended to facilitate the integration “GEN” connected service panel. This setup
enables the utilization of the “Smart Load” function.
3. There is no need for a transfer switch. Connect the “LOAD” output to the main panel.
4. DO NOT use “Grid Sell” mode when Off-Grid. ONLY “Limited Power to Load” (default).
5. When using a Generator in an Off-Grid situation, it is recommended to change the “Grid Mode” to “General Standard” and a “Grid
Reconnect Time” to 30 seconds. See section 2.5 “Integrating a Generator” for detailed instructions.
6. The Auto Gen-Start activates when the battery voltage (V) or percentage (%) reaches the pre-set “Start V / %” value. Subsequently, the
generator will sustain the charging process until the batteries reach approximately 95% capacity.
This is a non-modifiable upper limit unless Time of Use is enabled and programmed.
7. Remember to set the battery capacity and reasonable charge/discharge rates.
Grid-Tie PV Only, No Battery Configuration
1. Check the 🗹 No Battery” setting: Battery Setup Batt No Battery . The inverter will fault momentarily.
2. A complete Power Cycle IS REQUIRED when changing the battery mode to No Battery. See section 2.12, Power cycle Sequence”
for detailed instructions.
3. Enable 🗹 Grid Sell”: Limiter Grid Sell. Make sure to disable all other modes.
4. Tap the battery Icon to access the Details Screen and verify grid parameters and power import/export.
4.1 Battery Charge Controller
2-Stage Charging
The MPPT charge controller is 2 stage (CC/CV) type
controlled by the BMS when in closed loop mode for
optimized and safe charging. Fig 33 shows the
charging stage sequence.
Constant Current (CC) Stage
In the Constant Current stage, the battery is not at a
100% state of charge and has not yet reached the
Constant Voltage setpoint. The controller will deliver
100% of available solar power to recharge the
battery.
Constant Voltage (CV) Stage
When the battery has reached the Constant Voltage setpoint, the Sol-Ark inverter will regulate charging current to maintain the batteries
voltage at the CV setpoint, preventing overcharging. The battery is allowed to come to a full state of charge at the CV setpoint. Constant
Voltage lasts until the BMS sets the Charge Current Limit to 0A.

(highlighted in blue).
B. To ensure you have the latest firmware, visit https://www.Sol-
Ark.com/resources/software-updates/ to schedule an update, or contact
Sol-Ark Tech Support at [email protected]
C. Parallel systems REQUIRE that each inverter has its own HV battery /
battery bank.
D. If you do not have batteries on all inverters only parallel the units which
have a battery bank. All other units should be set to “Grid Sell” under
SettingsLimiter.
E. All GRID, GEN, and LOAD ports must be electrically parallelled with ALL parallel inverters.

5.2 Parallel Systems Programming
1. Program each inverter for parallel operation: Basic Setup Parallel
🗹
Parallel”
2. Assign a “Master” inverter, Modbus SN: 1
3. Assign all other units as “Slave” | Modbus SN: 02, 03, 04…etc.
4. Connect communication cables between the inverters using the included RJ45 cable in daisy-chain configuration between ports:
“Parallel_1” or “Parallel_2” from Master to Slave and then from Slave to Slave thereafter.
5. Perform a power cycle (see section 2.12 “Power Cycle Sequence” for power cycle sequence instructions).
6. Once the power cycle is completed, turn on the “Slave” units FIRST. Then turn ON the “Master” LAST.
7. Inverters will likely fault momentarily with F29 and F41 codes until all inverters are ON.
NOTE: When integrating a generator, it must be connected to all the systems in parallel. The
inverter assigned as “Master” will control the two-wire start feature so the generator contacts
should be connected to this inverter only.
Figure 36 Parallel Setup Tab
NOTE: If an inverter goes into a fault state, all other units will stop and the system will automatically
try to restart. If the system faults 5 consecutive times, it will stop completely and it will require a
manual restart. See section 2.12 “Power cycle sequence” for detailed instructions.

5.3 Troubleshooting Phase Sequence
If the screen of the Sol-Ark inverter shows the error in Fig 35, ensure the phase sequence follows the “Phase Type” programmed under
Grid Setup Grid Selection. The message “Grid Phase Wrong” is displayed when the inverter does not detect the correct phase
sequence. This situation can cause overloads faults in the system (F18, F26, F34) even with the “LOAD” disconnected and WILL CAUSE
DAMAGE to the equipment if it is not corrected.
If the programmed phase type is “0/240/120”, ensure the wiring follows a positive sequence A-B-C. If the programmed phase type is
“0/120/240” ensure the wiring follows a negative sequence A-C-B.
Figure 37 Grid Phase Wrong Error
Troubleshooting “Grid Phase Wrong”
Measure L-L voltages from “GRID” to “LOAD” terminals.
Voltage between lines should be 0Vac.
Measuring a voltage different than 0Vac means the lines are not the same phase.
Be sure to check both “GRID” and “LOAD” terminal connections; both must be correct. If the error persists you will need to check your AC
connection beyond the inverter and you will need to verify that the phases are correctly labeled from your meter.

8.1 Sol-Ark Warning and Fault codes
Fault
Description
Common Cause/Remedy
W03
Grid_Phase_Warn
Grid phasing sequence error. Verify order of the three phases of the GRID input are in
the order ABC, or change the phase setting value on the LCD.
W04
Meter_Offline_Warn
Communication failure with external revenue grade meter. Verify that the meter is
powered on and the RJ45 connection is secure.
W31
BMS_LostComm_Warn
Contact Sol-Art Support.
W32
Parallel_Comm_Warn
The quality of parallel inverter communication is poor. Communication is possible but
there may be packet loss. Verify if the DIP switch of each inverter is set to 'ON'. Check
the length of the parallel communication cables, the length should not be more than
16ft (5m) between inverters.
F1
DC_Inversed_Failure
Verify that the PV input wires are not reverse polarity.
If you have parallel systems and turn one system off, you will get this notification.
F8
GFDI_Relay_Failure
Check for continuity on the inverter's neutral and ground. Ensure there is only ONE
neutral-to-ground bond in the system. Current Leakage from inverter AC output to
Ground, check Ground and neutral are connected at the main panel.
F13
Grid_Mode_change
It can happen when not using batteries or if Grid Input settings are changed. This is a
notification, NOT a fault. If you switch from No Batt to Battery mode, power the system
down completely to restart.
F15
AC_OverCurr_Failure
It is usually caused by Loads too large for the inverter. If Off-Grid, the battery discharge
Amps are programmed too low. Overloads can result in F15, F18, F20, or F26.
F16
GFCI_Failure
Ground fault. Check PV+ or PV- wiring (which must be ungrounded). Exposed PV
conductors + rain can also cause. Check that the neutral line and Ground are not
double-bonded (common with portable generators).
F18
HW_Ac_OverCurr_Fault
Overloaded the Load Output (reduce loads) or overloaded a generator (reduce Gen
Start A). Wiring Short on the AC Side can also cause this error. Overloads can result in
F15, F18, F20, or F26.
F20
Tz_Dc_OverCurr_Fault
It is typically caused by DC current from the battery that is too large (ex: 4 Ton AC Unit)
or too much PV current (3 or more strings in parallel). Overloads can result in F15, F18,
F20, or F26.
F22
Tz_EmergStop_Fault
Initiated emergency stop by opening the B/B circuit. Reset e-stop button (close
contacts) to clear fault.
F24
DC_Insulation_Fault
An exposed PV conductor combined with moisture is faulting (can cause F16, F24, and
F26).
F25
DC_Feedback_Fault
No battery connection to the Inverter and Activate Battery is enabled. Disable Activate
Battery in settings while no battery is connected.
F26
BusUnbalance_Fault
Too much load on one leg (L1 or L2) vs. the other leg or DC loads on the AC output
when Off-Grid. Grounded PV+/- wire can cause F20, F23, or F26.
F29
Parallel_CANBus_Fault
Usually, a communication error for parallel systems. Check cables, and MODBUS
addresses.
F31
AC_SlaveContactor_Fault
Soft Start of the large motor failed.
F34
AC_Overload_Fault
AC Overload or load shorted. Reduce heavy loads.
F35
AC_NoUtility_Fault
Grid connection lost.
F37
DCLLC_Soft_Over_Cur
Software DC overcurrent.
F39
DCLLC_Over_Current
Hardware DC overcurrent.
F40
Batt_Over_Current
Batteries exceeded their current discharge limit.
F41
Parallel_System_Stop_Fault
If one system faults in parallel, this normal fault will register on the other units as they
disconnect from the grid.
F45
AC_UV_OverVolt_Fault
Grid under voltage causes a disconnect. This will self-reset when the grid stabilizes.
F46
Battery_Backup_Fault
Cannot communicate with other parallel systems. Check Master = 1, Slaves = 2-9 and
that ethernet are connected.
F47
AC_OverFreq_Fault
Grid over Frequency (common in power outages) causes disconnect. Will self-reset
when grid stabilizes.
F48
AC_UnderFreq_Fault
Grid under Frequency (common in power outages) causes a disconnect. Will self-reset
when grid stabilizes.

internal reading. Check external breakers and BMS battery relay status.
F52
DC_VoltHigh_Fault
HV bus V is too high. Please reboot inverter and wait to see if fault comes back. Check
PV and Batt V.
F54
BAT2_VoltHigh_Fault
PV may be higher than 500V. Battery voltage should not be above 59V or 63V
(depending on the model).
F55
BAT1_VoltHigh_Fault
Batt Voltage on input 1 is too high. Verify V reading on inverter screen and with meter.
Stop operation and immediately check with the battery manufacturer.
F56

Sol-Ark is programmed to BMS Lithium Battery Mode but cannot communicate with a
BMS. BMS_Err_Stop is enabled, but cannot communicate with a battery BMS
F59
BAT_OverCurr_Fault
Excessive load is drawing too much current from the battery
The battery voltage is too low for the inverter to operate
F60
Gen_Volt_or_Fre_Fault
Generator Voltage or Frequency went outside the allowable range.
F61
Button_Manual_OFF
The parallel “slave system turned off without turning off the “master.
F63
Arc_Fault
It can be a poor PV connector / Connection, or sometimes a false alarm due to
powerful lighting storms.
