Inverter failure
PV Over Voltage
1)
Check the open PV voltage to see whether it is greater than or too close to 450Vdc for APV 1700-2M-
TL-US or 500Vdc for APV 2300-2M-TL-US and APV 3100-2M-TL-US.
2)
If PV voltage is less than 450Vdc for APV 1700-2M-TL-US or 500Vdc for APV 2300-2M-TL-US and APV
3100-2M-TL-US, and the problem still occurs, please contact your local Service Centre.
Consistent Fault
1)
Disconnect PV (+) or PV (-) from the input, restart the PV inverter.
2)
If this fails to clear the fault, please contact our Service Centre.
> If there is no display on the panel, please check PV input connections.
If the voltage is higher than 150V, please contact your local Service Centre.
> 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.
