9.1.2 For the Faults on the APP or Screen
If the Wi-Fi module or ZE100 (integrated with Wi-Fi function) is equipped, a fault icon
will be shown in the APP once a fault occurs. For details, see the related munals.
If the LCD module eShow is equipped, the “Fault” state will display on the main
screen. For details, see eShow User Manual. Follow the procedure below for
troubleshooting when the data on the main screen cannot update in real time.
1.
Disconnect the external AC circuit breaker.
2.
Disconnect the external DC circuit breaker or pull off the DC connectors.
3.
Reconnect the breakers or connectors and restart the inverter.
4.
If the fault still exists, check whether the communication cable of eShow is
firmly connected
5.
If the communication cable is firmly connected, contact Sungrow Service
Dept.

Troubleshooting
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.
