Fault Code
Solution
Grid Voltage Fault
- Wait for one minute, grid may go back to normal working state.
- Make sure that grid voltage and frequency complies with standards.
- Or, please seek help from us.
Consistent Fault
- Disconnect PV (+), PV (-) with DC.
- After the LCD switches off, reconnect and check again.
- Please seek help from us if it cannot go back to normal state.
Isolation Fault
- Check the impedance among PV (+), PV (-) and ground. Impedance
should be >1Mohm.
- Please seek help from us if it cannot be detected or the impedance is
<1Mohm.
Ground Fault
- Check the voltage of neutral and PE.
- Check AC wiring.
- Restart inverter, if error message persists, seek help from us.
OCP
- Turn off the PV and grid, reconnect them.
- Or seek help from us if it does not go back to normal.
PLL Fault
- System will reconnect if the utility is back to normal.
- Or seek help from us if it does not go back to normal state.
PV OVP
- Check the panel
’
s open-circuit voltage whether the value is similar or
already >550Vdc.
- Please seek help from us when voltage
≤
550Vdc.
Relay Fail
- Disconnect PV (+), PV (-) with DC.
- After the LCD switches off, reconnect and check again.
- Please seek help from us if it does not go back to normal state.
Sample Fault
- Disconnect PV (+), PV (-) with DC.
- After the LCD switches off, reconnect and check again.
- Please seek help from us if it cannot go back to normal state.
Comm Lost
- Disconnect PV+, PV-, reconnect them.
- Or seek help from us if it does not go back to normal state.
MS Comm Lost
- Disconnect PV (+), PV (-) with DC.
- After the LCD switches off, reconnect and check again.
- Please seek help from us if it cannot go back to normal state.
Over Temp
- Check if the environment temperature is over the limit.
- Or seek help from us.
