Hi everyone,
I am new in inverters. Please help me to understand root cause of following issue.
My configuration:
Growatt SPF5000ES + 48v100ah rack pack
Inverter and battery connected using cable from battery set(BMS port on inverter side, RS485 port on battery side)
Inverter program 05 set to LI, program 036 set to L01. Connection successful, seems all working well
inverter program 021(cutoff percentage) set to 20%
I have following issue during discharge:
When 5% remain till cutoff percentage, inverter starts show fault 04(low battery voltage), while battery has same voltage as few minutes ago
I've tested several cases with different cutoff percentage, same result. When 5% remains to cutoff, error shown.
Then I start charging, fault 04 will disappear when battery reach 30%.
Thanks for help!
