002
The grid voltage exceeds
inverter allowable upper
limit.
1. Check the voltage of the grid.
2. If the grid voltage exceeds the permissible
range of inverter protection parameters, ask
utility grid company for solution.
3. If the grid voltage is within the permissible
range, contact Sungrow Service Dept..
003
Grid transient voltage
exceeds the permissible
range
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 is below
inverter’s allowable lower
limit.
1. Check the grid voltage.
2. If the grid voltage exceeds the permissible
range of inverter protection 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
allowable upper limit.
1. The inverter will resume if the output current
falls below the protection value.
2. If the fault still exists, please contact
Sungrow Service Dept..
007
Transient AC overcurrent
1. The inverter will self-recover after several
seconds.
2. If the fault still exists, please contact
Sungrow Service Dept..
008
The grid frequency
exceeds inverter
allowable upper limit.
1. Check the grid frequency.
2. If the grid frequency exceeds the permissible
range of inverter protection 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 is
below the inverter
allowable lower limit.
