Explanation:
The inverter has determined that the requirement (stand-alone grid formation) for grid connection is not met. There will be temporary disconnections from the utility grid on the part of the inverter as a result.
This event rarely occurs before the inverter is connected. The inverter repeats the test and then connects to the utility grid.
Corrective measures:
Check whether the selected country data set meets the local standards and guidelines of the electric utility company.
Check whether the grid voltage is in the permissible range.
Check whether the voltage difference between neutral conductor N and protective grounding PE is < 10 V. Check the AC installation path for loose or detached electrical connections.
