When faults occur, "Fault" state can be shown in the smartphone application
interface.
Fault
Description
Code
The grid voltage exceeds
002 inverter allowable upper
limit.
Grid transient voltage
003 exceeds the permissible
range
The grid voltage is below
004 inverter's allowable lower
limit.
The grid voltage is too
005
low.
The AC output current
006 exceeds
allowable upper limit.
007 Transient AC overcurrent
The grid
008 exceeds
allowable upper limit.
The grid frequency is
009 below
allowable lower limit.
Troubleshooting
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..
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..
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..
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..
1. The inverter will resume if the output current
falls below the protection value.
