Sol-Ark 12K Error Codes
Fault
Instruction
Common Cause/Remedy
F1
DC Inversed Failure
If you have parallel systems and turn one system off, you with get this notification. Not a fault.
F8
GFDI_Relay_Failure
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
Tz_Ac_OverCurr_Fault
Overloaded the Load Output: reduce loads. 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). Overloads can
result in F15, F18, F20, or F26.
F22
Tz_EmergStop_Fault
Initiated Emergency Stop; see sensor pinout table.
F23
Tz_GFCI_OC_Fault
PV Ground fault. Check PV+ or PV- wiring (which must be ungrounded or damage can occur). Typically
caused by pinched PV wire grounding the PV+ or PV-. Grounded PV wire can cause F20, F23, or F26.
F24
DC_Insulation_Fault
An exposed PV conductor combined with moisture is faulting (can cause F16, F24, F26).
F25
AC_Active_Batt_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
F30
AC_MainContactor_Fault
Contact Sol-Ark.com
F31
Soft_Start_Failed
Soft Start of 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
If one system faults in parallel, this normal fault will register on the other units as they disconnect from grid
F45
AC_UV_OverVolt_Fault
Grid under voltage causes a disconnect. This will self-reset when grid stabilizes.
F46
Parallel_Aux_Fault
Cannot communicate with other parallel systems. Check Master = 1, Slaves are 2-9, ethernet cables are
connected.
F47
AC_OverFreq_Fault
Grid over Frequency (common in power outages) causes a 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.
F55
DC_VoltHigh_Fault
PV may be higher than 500V. Battery voltage should not be above 59V or 63V (depending on the model).
F56
DC_VoltLow_Fault
Batteries are overly-discharged, or Lithium BMS has shut down. If battery settings are off, this can also
happen.
F58
BMS communication fault
Sol-Ark is programmed to BMS Lithium Battery Mode but cannot communicate with a BMS
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 Master
F63
ARC_Fault
It can be a lousy PV connector/connection. And sometimes a false alarm due to powerful lightning storms.
F64
Heatsink_HighTemp_Fault
Check the built-in fans are running; ambient temp may be too high
