Troubleshooting
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.
