sol-ark 5K - Common Battery Application Notes

April 21, 2021 39
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 disconnect. Will self-reset when grid stabilizes.
F48
AC_UnderFreq_Fault
Grid under Frequency (common in power outages) causes disconnect. Will self-reset when grid stabilizes.
F49
AC_U_GridCurr_DcHigh_Fault
Contact Sol-Ark.com
F55
DC_VoltHigh_Fault
PV maybe higher than 500V. Battery voltage should not be above 59V or 63V (depending on model).
F56
DC_VoltLow_Fault
Batteries are overly discharged or Lithium BMS has shutdown. 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 allowable range
F61
Button_Manual_OFF
Parallel Slave system was turned off without turning off Master
F63
ARC_Fault
Can be a bad 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

These settings will charge the batteries off solar only.
Discharge the batteries down to a maximum of 70% full.
Limited To Home mode will not sell to the grid from the
batteries (only the home will use battery power). The
100% time slot is to ensure that the batteries are
properly cycled each day.
