Class 5 Status
Codes Class 5 status codes generally do not impair grid power feed operation, but can lead to lim-
itations. They will be displayed until the status code is acknowledged by pressing a key (the
inverter, however, continues working normally in the background).

Inverter does not feed ener-
gy into the grid.
