diagnosis and solution
1. Check open PV voltage, if it is too close to or over 750 VDC.
2. If PV voltage is less than 750 VDC and the problem still occurs,
please call service.
1. Disconnect PV(+) and PV(-) from the input, start the unit again.
2. If it does not work, please call service.
1. The internal temperature is higher than specified normal value.
2. Reduce the ambient temperature by appropriate and effective
activities.
3. Or move inverter to a cooler location.
4. If it does not work, please call service.
1. Disconnect PV(+) and PV(-) from the input, start the unit again.
2. If it does not work, please call service.
1. Input DC current is higher than the permissible value.
2. Observe the faulty condition for 1 minute.
3. If the system does not restore to normal operation, please call
service.
1. Disconnect PV(+) and PV(-) from the input, start the unit again.
2. If the system does not restore to normal operation, please call
service.
1. Disconnect PV(+) and PV(-) from the input, start the unit again.
2. Check if L-LINE and N-Neutral are mistakenly connected.
3. If so, please call service.
1. Disconnect PV(+) and PV(-) from the input, start the unit again.
2. If the system does not work, please call service.
