Fault Code
Solution
VGridTransient Fault
- Disconnect PV (+), PV (-) using DC switch.
- After the LCD switches off, reconnect and check again.
- Please seek for help from us if it does not go back to normal state.
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 for help from us.
Consistent fault
- Disconnect PV (+), PV (-) using DC switch.
- After the LCD switches off, reconnect and check again.
- Please seek for 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 for 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.
- Disconnect PV (+), PV (-) using DC switch.
- After the LCD switches off, reconnect and check again.
OCP
- Turn off the PV and grid, reconnect them.
- Or seek for 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 for 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 >1000Vdc.
- Please seek help from us when voltage ≤1000Vdc.
Relay fail
- Disconnect PV (+), PV (-) using DC switch.
- After the LCD switches off, reconnect and check again.
- Please seek for help from us if it does not go back to normal state.
Sample fault
- Disconnect PV (+), PV (-) using DC switch.
- After the LCD switches off, reconnect and check again.
- Please seek for help from us if it cannot go back to normal state.
Comm Lost
- Disconnect PV+, PV-, reconnect them.
- Or seek for help from us if it does not go back to normal state.
