Event message Description Type
Device overheated
In spite of capacity reduction, the maximum permis-
sible temperature is exceeded. The inverter does not
inject into the grid until the permissible tempera-
ture range is reached.
1. Check whether the installation conditions are ful-
filled.
2. Contact your installer if this alarm occurs fre-
quently.
Data transfer failed
A setting failed, for example during initial commis-
sioning, because it has not been properly adopted.
u Repeat the setting.
u Contact your installer if this error occurs fre-
quently.
Fan faulty
The internal fan of the inverter is defective. It is pos-
sible that the inverter injects into the grid with
reduced capacity.
u Notify your installer.
FE not connected
The protective earth is not connected. For safety
reasons the inverter is not allowed to inject into the
grid.
u Notify your installer.
Grid current DC offset
too high
The DC current power share that is injected by the
inverter into the grid, exceeds the permissible value.
Pursuant to statutory regulations, the inverter
switches off automatically as long as this fault is
pending.
u Notify your installer.
Grid frequency too high
The grid frequency applied on the inverter exceeds
the permissible value. Pursuant to statutory regula-
tions, the inverter switches off automatically as
long as this fault is pending.
u Contact your installer if this error occurs fre-
quently.
Grid frequency too high
for reactivation
After switch-off, the inverter cannot inject again
because the grid voltage exceeds the legally pre-
scribed switch-on value.
u Contact your installer if this error occurs fre-
quently.
Grid frequency too low
The grid frequency applied on the inverter is below
the permissible value. Pursuant to statutory regula-
tions, the inverter switches off automatically as
long as this fault is pending.
u Contact your installer if this error occurs fre-
quently.
