Recommended solution
P001
The leakage
current is too high
1.Cut off the DC breaker and check if there is ab-
normity in the AC side;
2.After the fault is removed, close the DC breaker
and restart the inverter;
3.If the fault occurs repeatedly, pleas ask for
professional service.
1.Check if the inverter is normally connected to
the grid;
2.Check if the grid voltage and frequency are
complying with the output scope of the inverter;
3.If the fault above is removed but the inverter can
still not work normally, please ask for professional
service.
1.Cut off the DC breaker;
2.Check if the resistance between the +/- poles of
the PV assembly and the ground is larger than1M ;
3.If the fault above is removed but the inverter can
still not work normally, please ask for professional
service.

1.Cut off the DC breaker;
2.Check if DC input is higher than 550V;
3.If the fault above is removed but the inverter can
still not work normally, please ask for professional
service.
