Check item Fault description Solution
PV2 over-voltage
PV2 voltage exceed
allow value
Check the PV2 voltage to see if it is exceeds
585V, if exceed, reduce the PV array quantity.
PV2 over-current
PV2 current exceed
allow value
1. Try to lower PV power.
2. Restart the inverter to see if the fault still
exists. If it still exists, contact customer service.
PV over-temperature
PV side temperature is
too high.
1. Try to lower the ambient temperature.
2. Make sure that the inverter is installed
according to the manual and there is no shelter
around the inverter.
3. After the inverter is powered off and waiting
for 30 minutes, then restart it. If the fault still
exists, contact service.
BMS communication
fault
Abnormal
communication with
BMS.
Check whether communication wire between
BMS and inverter is loosed.
Battery inner fault
Shutdown fault from
BMS.
Check the fault code position question from
BMS on APP.
Inverter side
over-temperature
Inverter heat sink
ambient temperature is
too high.
1. Try to lower the ambient temperature.
2. Make sure that the inverter is installed
according to the manual and there is no shelter
around the inverter.
3. After the inverter is powered off and waiting
for 30 minutes, then restart it. If the fault still
exists, contact service.
Inverter voltage
abnormal
Output voltage
abnormal
Check whether voltage and load of grid is
abnormal.
Short-circuit
protection
When off-grid, the
output side is
short-circuited
1. Use a multimeter to test the impedance of the
off grid output. If it is small, check whether the
wiring is correct
