Solution
1. Check whether Grid is abnormal.
2. Confirm whether the grid cable connection is
normal.
3. Restart inverter and check whether the fault is
existing.
1. Check whether the input voltage of PV1 and
PV2 ex-ceeds 580V.
2. If the first one does not exist, restart the inverter
to see if the fault still exists. If it still exists, please
call the service center.
1. Check whether PV cable connection is
reliable.
2. Check whether PV cable is damaged.
1. Restart inverter and check whether the fault is
existing.
1. Check whether the environment around
inverter is with poor heat dissipation.
2. Confirm whether inverter installation meet the
installation requirements.
Restart the inverter and check whether the fault is
existing.
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.
Check the PV2 voltage. If it exceeds 585V, 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.
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.
