Event message Description Type
Grid frequency
too low
The grid frequency applied on the inverter is below the permis-
sible value. Pursuant to statutory regulations, the inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid frequency
too low
reactivation
After switch-off, the inverter cannot inject again because the
grid voltage is below the legally prescribed switch-on value.
u Contact your installer if this error occurs frequently.
Grid islanding
detected
The grid is not carrying any voltage (self-run of the inverter).
For safety reasons the inverter is not allowed to inject into the
grid. It switches itself off as long as the error is present (display
dark).
u
Contact your installer if this error occurs frequently.
Grid relay
defective
The inverter has detected that a grid relay is defective; for this
reason, it is not injecting into the grid.
u
Notify your installer.
Grid voltage too
high
The grid voltage applied on the inverter exceeds the permis-
sible value. Pursuant to statutory regulations, the inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid voltage
Æ
too high
The output voltage averaged over the legally prescribed time
period exceeds the permissible tolerance range. The inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid voltage too
low
The grid voltage applied on the inverter is below the permis-
sible value. Pursuant to statutory regulations, the inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid voltage
Æ
too low
The output voltage averaged over the legally prescribed time
period is below the permissible tolerance range. The inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid voltage too
high for
reactivation
After switching off, the inverter cannot resume feeding
because the grid voltage exceeds the legally prescribed switch-
on value.
u
Contact your installer if this error occurs frequently.
Grid voltage too
low for
reactivation
After switch-off, the inverter cannot inject again because the
grid voltage is below the legally prescribed switch-on value.
u
Contact your installer if this error occurs frequently.
