Troubleshooting
When the data on the screen of eShow cannot be refreshed on time, please follow
the procedure below for a solution.
Step 1
Disconnect the external AC circuit breaker firstly.
Step 2
Turn off the upstream DC circuit break or pull off the MC4 terminal.
Step 3
check whether the communication cable of the eShow is firmly connected
Step 4
If the fault still exists, contact Sungrow Service Dept.
When faults occur, the “Fault” state will be shown on the main screen.

Troubleshooting
002
The grid voltage exceeds
the 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
the local utility grid authority 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.
