Possible actions
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.
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 200VDC (for Omniksol-1k/1.5k-TL-M).
2. If PV voltage is less than 200VDC, and the problem
still occurs, please call local service.
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.
