F55 DC_VoltHigh_Fault
PV may be higher than 500V. Battery voltage should not be above
500V (depending on the model).
F56 DC_VoltLow_Fault
Batteries are overly discharged, the Inverter is off-grid and exceeds
programmed batt discharge current by
20%, or Lithium BMS has
shut down. If battery settings are incorrect, 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 the Master.
F63 ARC_Fault
It can be a poor PV connector/connection. And sometimes a false
alarm due to powerful lightning storms.

Check that the built-

high. Ensure proper clearance.
4.6 Battery System Debug and Maintenance
4.5.1 Battery System Debug
This system debug is for BESS system (Battery Energy Storage System). BESS system can’t debug alone. It must
operate with configured UPS, INVERTER and EMS system together.
Preparation for debug.
Turn on the BESS system, referring to section 3. Before turning on the
whole BESS system, starting up of the load is not allowed!
Remark: Besides the BESS, if other equipment has its own system
starting up step, be sure to follow its own system operation menu.
System function test.
Each component system debug:
Power supply from the External Power Suppler (e.g. UPS) is working
normally.
Communication Test: Check if the communication between the BESS
system and communicated devices normal or not, alarm equipped or
not.
Power Conversion System Test: Before conjoint test be sure test the
Inverter System starting up progress at first. And check if the
parameters meet BESS requirement or not.
BESS Test: Charge/Discharge test; Stop test when charging, stop
discharging, current limiting functions, etc.
Caution: Before turning on the BESS system, be sure setup all the
parameters of the INVERTER and EMS at first.
Monitor function test.
(If configured.)
Check if the data of the BESS system is showing on the monitor system
normally.
EMS monitoring test
(If configured.)
If the EMS system has been configured, check the information
uniformity and command functionality following the BMS protocol.
Trial operation test.
After the system debugged, run the system a period as test (testing
with low load), to test if the high voltage DC system is fit for the contract.
