Event message Description Type
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
permissible 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 permissible 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.
