Troubleshooting 

011 

DC injection 
over-current. 
The DC current 
injection  of AC current 
exceeds the 

upper 

limit. 

1. Wait a moment for inverter recovery. 
2. If the fault occurs repeatedly, contact 
Sungrow Service Dept.   

012 

Leakage current 
over-current. 
The leakage current 
exceeds 

inverter 

allowable upper limit. 

1. Check the PV strings for ground fault. 
2. If the fault occurs repeatedly, contact 
Sungrow Service Dept. 

014 

10-minute grid 
over-voltage. 
The average grid 
voltage  in  10 minutes 
exceeds the 
permissible range. 

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. 

015 

Grid over-voltage   
The grid voltage 
exceeds  the protective 
value, which is higher 
than the protective 
value of error 002. 
(stage II) 

1. Check the model of the AC cables. 
2. Wait a moment for inverter recovery. 
3. If the grid voltage exceeds the 
permissible range, ask utility grid company 
for solution. 
4. If the fault occurs repeatedly, contact 
Sungrow Service Dept. 

016 

The bus voltage or 
power is high. 

1. Wait a moment for inverter recovery. 
2. If the fault occurs repeatedly, contact 
Sungrow Service Dept. 

019 

Bus transient 
over-voltage. 
The transient bus 
voltage exceeds 
inverter allowable 
upper limit. 

1. Wait a moment for inverter recovery. 
2. If the fault occurs repeatedly, contact 
Sungrow Service Dept. 

020 

Bus over-voltage. 
The bus voltage 
exceeds 

inverter 

allowable upper limit. 

1. Wait a moment for inverter recovery. 
2. If the fault occurs repeatedly, contact 
Sungrow Service Dept. 

021 

PV1 input over-current. 

Check the layout and the wiring of PV1 
input. 

022 

PV2 input over-current. 

Check the layout and the wiring of PV2 
input. 

028 

PV1 reverse 
connection. 

Check the cable connections of PV1. 

029 

PV2 reverse 
connection. 

Check the cable connections of PV2.
