Installation Manual
Description
Grid frequency too high.
The inverter has disconnected
from the utility grid. A
stand-alone grid or a very
large change in the power
frequency was detected.
DC current share in the AC
voltage too high.
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 the grid
voltage was below or above a
certain level.
DC-component in AC current is
to high
Grid frequency too low.
Grid frequency too high.
DC current share in the AC
voltage too high (stage 2).
Grid failure, open phase
detected.
Measure
Check power frequency.
Check grid frequency change.
For repeated daily occurrences,
perform onsite grid analysis.
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 DC cables
and modules.
Check grid frequency, grid
voltage, software version and
grid code setting.
If this event is reported several
times each day, perform onsite
grid analysis.
If this event is reported several
times each day, perform on-site
grid analysis.
Check grid frequency and AC
installation.
Check grid 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.
