Should any problems arise, the red (Fault) LED on the front panel turns on and the
LCD displays the relevant information. Please refer to the following table for a list
of potential problems and their solutions.
1. The ground current is too high.
2. Unplug the inputs from the PV generator and check the
peripheral AC system.
3. After the cause is cleared, re-plug the PV panel and check
PV-Inverter status.
4. If the problem persists please call service.
1. Wait for 5 minutes, if the grid returns to normal, PV-Inverter
automatically restarts.
2. Make sure grid voltage and frequency meet the specifications
3. If the problem persists please call service.
1. Grid is not connected.
2. Check grid connection cables.
3. Check grid usability.
1. Check the open PV voltage, see if it is greater than or too close
to 550VDC.
2. If PV voltage is less than 550VDC, and the problem still occurs,
please call local service.
1. Disconnect PV (+) or PV (-) from the input, restart the
PV-Inverter.
2. If it does not work, call service.
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.
