Troubleshooting
1. Check whether AC circuit breaker is
triggered.
2. Check whether AC cables are all firmly
connected.
3. Check whether grid is not in service.
4. If all conditions are OK and this fault still
occurs in the LCD screen, contact Sungrow
Service Dept.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
1. Check the PV strings for ground fault.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept.
1. Check whether the inverter selected
country code is the country you are in.
2. Wait a moment for inverter recovery.
3. Check the voltage of the grid. If the grid
voltage exceeds the permissible range of
inverter protection parameters, ask utility
grid company for solution.
4. If the fault occurs repeatedly, contact
Sungrow Service Dept.
1. Check the model of the AC cables.
2. Wait a moment for inverter recovery.
3. If the grid
permissible range, ask utility grid company
for solution.
