1. Try to reduce the PV power.
2. Restart the inverter to see if the fault still exists. If it still
exists, contact service.
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 ser-
vice.
Check whether the actual battery voltage exceeds the bat-
tery charging cut-off voltage by more than 20V.
Check whether the actual battery voltage is lower than the
battery discharge cut-off voltage.
Confirm that the wiring is normal, and check whether the
battery voltage sampling value is less than 75V.
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 ser-
vice.

The effective value of grid voltage exceeds the maximum
protection value of national standard voltage.
1. Whether the off grid output terminal is short circuited or
has impact load.
2. Restart the inverter to see if the fault still exists. If it still
exists, contact service.
Restart the inverter to see if the fault still exists. If it still ex-
ists, contact service.
1. Check whether the off grid output terminal is overloaded,
short circuited or has impact load.
2. Restart the inverter to see if the fault still exists. If it still
exists, contact service.
