Inverter Failure

 

1.

Check the open PV voltage, see if it is greater than or too close

PV over Voltage

 

to 450VDC

2.

If PV voltage is less than 450VDC, and the problem still occurs,

 

 

 

please call local service

 

1.

Disconnect PV (+) or PV (-) from the input, restart the PV-

Consistent Fault

 

Inverter

 

2.

If it does not work, call service

 

1.

The internal temperature is higher than specified normal value

Over Temperature

2.

Find a way to reduce the ambient temperature.

3. Or move the inverter to a cooler environment

 

4.

If it is not effective, call local service

Relay Failure

 

 

 

DC INJ High

 

 

 

EEPROM Failure

 

 

1. Disconnect ALL PV (+) or PV (-)

SCI Failure

2. Wait for few seconds

 

High DC Bus

3. After the LCD switches off, reconnect and check again

 

Low DC Bus

4. If the message reappears call your local service

 

Ref 2.5V Fault

 

 

 

DC Sensor Fault

 

 

 

GFCI Failure

 

If there is no display on the panel, please check PV-input connections.

If the voltage is higher than 150V, call your local service.

During periods of little or no sunlight, the PV-Inverter may continuously start up and shut down. This is due to insufficient power generated to operate the control circuits.
