• 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.
Inverter Failure
PV over Voltage
1. Check the open PV voltage, see if it is greater than or too close
to 450VDC
2. If PV voltage is less than 450VDC, and the problem still occurs,
please call local service
Consistent Fault
1. Disconnect PV (+) or PV (-) from the input, restart the PV-
Inverter
2. If it does not work, call service
Over Temperature
1. The internal temperature is higher than specified normal value
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
1. Disconnect ALL PV (+) or PV (-)
2. Wait for few seconds
3. After the LCD switches off, reconnect and check again
4. If the message reappears call your local service
