Description
The residual-current monitoring
unit (RCMU) detected an
overcurrent.
The utility grid has been
outside the permissible range
for more than ten minutes
(frequency and/or voltage).
Fault ride through. The inverter
has detected that grid voltage
was below or above a certain
level.
Power frequency too low or
too high.
DC current share in utility grid
is too high (stage 2).
Grid failure, open phase
detected.
Grid failure.
Grid voltage on phase too low. Check voltage and AC
Measure
Turn off both DC and AC supply
and wait until the display turns off.
Then turn on DC and AC supply
and observe if the event reoccurs.
Visual inspection of all PV cables
and modules.
Check power frequency, grid
voltage, software version and
grid code setting.
If this event is reported several
times each day, perform onsite
grid analysis.
Check power frequency and AC
installation.
For repeated daily occurrences,
perform onsite grid analysis.
If the event reoccurs several times
each day, contact the responsible
grid operator.
If the event reoccurs several times
each day, contact the responsible
grid operator.
installation. If the voltage is zero,
check the fuses.
