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. Make sure that PV system and
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.
layout correspond to
recommendations in the
manuals.
Make sure that PV system and
layout correspond to
recommendations in the
manuals.
Check number of strings in
parallel and current ratings.
Has the current limit been
exceeded? Reconnect strings in
parallel.
