diagnosis and solution

Inverter Failure

PV Over Voltage

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.

Consistent Fault

1. Disconnect PV(+) and PV(-) from the input, start the unit again.

2. If it does not work, please call service.

SCI Failure

Over

Temperature

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.

Relay Failure

1. Disconnect PV(+) and PV(-) from the input, start the unit again.

2. If it does not work, please call service.

DC INJ High

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.

EEPROM Failure

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.

High DC Bus

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.

Low DC Bus

1. Disconnect PV(+) and PV(-) from the input, start the unit again.

2. If the system does not work, please call service.
