SwOCPInstant

The grid current is

too high.

Internal faults of the inverter; turn off

the “DC switch”, wait 5 minutes and

then turn it back on again. Check that

the fault is no longer present. If this is

not the case, contact Technical

Support.

ID30

SwBOCPInstant

The input current is

too high.

Check whether the input current is

higher than the maximum input

current of the inverter, then check

the input wiring; if both are correct,

contact Technical Support.
