MAINTENANCE AND TROUBLESHOOTING
Solution
Check the PV1 voltage. If it exceeds 585VDC,
reduce the number of PV modules.
1. Try to reduce the PV power.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
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,
please call the service center.

1. Try to reduce the PV power.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
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,
please call the service center.
Check whether the actual battery voltage exceeds
the battery 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,
please call the service center.
1. Try to reduce battery power.
