Grid Lost Fault
1 Please check grid-connection, e.g. wires, interface etc.
2 Checking grid usability.
3 Or seek for help from us.
PV Volt Fault
1 Check the panel’s open-circuit voltage whether the value is
similar or already >550Vdc.
2 Please seek help from us when voltage ≤550Vdc.
Sample Fault
1 Disconnect PV (+), PV (-) with DC.
2 After the LCD switches off, reconnect and check again.
3 Please seek for help from us if it cannot go back to normal state.
Over Temp
1 Check if the environment temperature is over the limit.
2 Or seek for help from us.
DCI Fault
1 Wait for one minute after the inverter reconnect to grid.
2 Disconnect PV (+), PV (-) with DC.
3 After the LCD switches off, reconnect and check again.
4 Please seek for help from us if it does not go back to normal state.
SPI Comm Lost
1 Disconnect PV (+), PV (-) with DC.
2 After the LCD switches off, reconnect and check again
3 Please seek for help from us if it does not go back to normal state.
IsolationFault
1 Check the impedance among PV (+), PV (-) and ground.
Impedance should be >1Mohm.
2 Please seek for help from us if it cannot be detected or the
impedance is <1Mohm.
Consist Fault
1 Disconnect PV (+), PV (-) with DC.
2 After the LCD switches off, reconnect and check again.
3 Please seek for help from us if it does not go back to normal state.
GFC Fault
1 Disconnect DC and AC connector, check the surrounding equipment
on the AC side.
2 Reconnect the input connector and check the state of inverter after
troubleshooting.
3 Please seek for help from us if it does not go back to normal state.
Relay Fail
1 Disconnect PV (+), PV (-) with DC.
2 After the LCD switches off, reconnect and check again.
3 Please seek for help from us if it does not go back to normal state.
