Figure 4.1 Grid-related events
34 STPS60-IA-xx-12
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 the grid
voltage was below or above a
certain level.
Grid 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 installation.
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 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.
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.
If the event reoccurs several times
each day, contact the responsible
grid operator.
If the voltage is zero, check the
fuses.
