1. Check the impedance between PV (+) & PV (-) and the inverter
is earthed. The impedance must be greater than 2MΩ.
2. Check whether the AC-side has contacts with earth.
1. The ground current is too high.
2. After cut off the AC side connection, 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 AC
connection, and check PV-Inverter status.
1. Wait for a moment, if the grid returns to normal, PV-Inverter
automatically restarts.
2. Make sure grid voltage and frequency meet the specifications.
1. Grid is not connected.
2. Check grid connection cables.
No Utility
3. Check grid usability.
4. If grid is ok, and the problem persists, maybe the fuse in the
inverter is open, please call service.
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.
1. Check the open PV voltage; see if it is greater than or too close
to 1000VDC (for Omniksol-10k-TL3 or Omniksol-13k-TL3).
2. If PV voltage is less than 1000VDC, and the problem still
occurs, please call local service.
Fault Disconnect PV (+) or PV (-) from the input, restart the inverter.
1. Disconnect ALL PV (+) or PV (-).
2. Wait for a few seconds.
3. After the LCD switches off, reconnect and check again.
4. If the problems remain please call local service.
