Description Troubleshooting
002
The grid voltage has exceeded
inverter allowable upper limit.
1. Check the voltage of the grid.
2. If the grid voltage exceeds the
permissible range of inverter protective
parameters, ask utility grid company for
solution.
3. If the grid voltage is within the
permissible range, contact Sungrow
Service Dept..
003
Inverter has checked that the
instantaneous sample value of
the grid voltage exceeds the
allowable limit for some time.
1. This is a short-term fault due to grid
condition. Wait a moment for inverter
recovery.
2. If the fault still exists, please contact
Sungrow Service Dept..
004
The grid voltage has fallen
below inverter’s allowable lower
limit.
1. Check the voltage of the grid.
2. If the grid voltage exceeds the
permissible range of inverter protective
parameters, ask utility grid company for
solution.
3. If the grid voltage is within the
permissible range, contact Sungrow
Service Dept..
005 The grid voltage is too low.
1. This is a short-term fault due to grid
condition. Wait a moment for inverter
recovery.
2. If the fault still exists, please contact
Sungrow Service Dept..
006
The AC output current exceeds
inverter protective limit.
1. The inverter will resume if the output
current falls below the protective value.
2. If the fault still exists, please contact
Sungrow Service Dept..
007
Inverter has checked AC
overcurrent temporarily. The inverter will self-recover after
several seconds.
008
The grid frequency has
exceeded inverter allowable
upper limit. 1. Check the frequency of the grid.
2. If the grid frequency exceeds the
permissible range of inverter protective
parameters, ask utility grid company for
solution.
3. If the grid frequency is within the
permissible range, contact Sungrow
Service Dept..
009
The grid frequency has fallen
below inverter allowable lower
limit.
