System characteristics during a mains fault
Mains faults can have an adverse effect on the charac-
teristics of the system.
In case of a mains fault (e.g. power cut), the mains
monitor (ENS) of the system automatically disconnects
it from the grid. Power export is interrupted.
No fault message is displayed.
If the mains fault is present for less than 60 seconds,
power export automatically resumes within 10 minutes.
If the mains fault is present for more than 60 seconds,
the fuel cell module of the system shuts down.
If the mains fault is no longer present, power genera-
tion by the system automatically resumes 24 hours
after its last start. If the same mains fault leads to a fur-
ther shutdown of the fuel cell module within 7 consecu-
tive days, there is a possibility of permanent mains
instability.
