Description
Too many PV modules
connected in parallel. Should
only appear on newly installed
systems.
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.
The DC voltage is too high.
DC voltage warning.
Too many PV modules
connected in parallel. Should
only appear on newly installed
systems.
Measures
Check number of strings in parallel
and current ratings. Has the current
limit been exceeded? Reconnect
strings in parallel.
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.
Warning: A repeated occurrence
of this message on several
consecutive days indicates a
general problem in the DC
insulation. In this case, a
comprehensive test of the insulation
is necessary, since even a sudden
ground fault during operation
cannot be excluded.
Warning: A ground fault during
operation can completely destroy
the device.
Make sure that PV system and
layout correspond to
recommendations in the manuals.
Make sure that PV system and
layout correspond to

Check number of strings in parallel
and current ratings. Has the current
