PV ISO too
low
The resistance between the PV
strings and ground (PE) is too
low for the inverter to be
commissioned. This will force
the inverter to make a new
measurement after ten minutes.
Make a visual inspection of all PV
cables and modules for correct
installation according to the
installation manual. The event could
indicate that the PE connection is
missing.

waiting
The DC voltage is too high. Make sure that PV system and
layout correspond to
recommendations in the manuals.
