Error message Description
The inverter cannot or may not feed the grid at full power because the
Derating: 10
average output voltage over a period of 10 minutes has been outside the
minute average
value > 30 min permissible tolerance range for over 30 minutes.

The inverter has received an external signal via the communications inter-

The communications card inserted into the inverter has signalled an error.
Option card fault
The communication to the outside world is possibly interrupted but the
inverter is otherwise operating without restrictions. Check the communica-
