Possible cause
Error message and Trouble Shooting
ERROR
1. Check the utility frequency on the
inverter terminal
2. Check country setting
3. Check the detection circuit inside the
inverter
1. Check the utility frequency on the
inverter terminal
2. Check country & Grid setting
3. Check the detection circuit inside the
inverter
Grid connection of inverter need to be
far away from non-linear load if necessary
1. Check the AC connection, must accords
to manual
2. Check the detection circuit inside the
inverter
1. Switch on AC breaker
2. Check the connection in AC plug and
make sure it connects to inverter
1. Check the utility voltage connection
to the inverter terminal
2. Check country & Grid setting
3. Check the connection in AC plug
4. Check the detection circuit inside the
inverter
1. Check the utility voltage on the inverter
terminal
2. Check the utility voltage on the inverter
terminal
3. Check country & Grid setting
4. Check the detection circuit inside the
inverter
1. Modify the solar array setting, and
make the Voc less than 1000Vdc
2. Check the detection circuit inside the
inverter
