frequency-dependent
power reduction is acti-
vated, and the frequen-
cy and voltage limits are
being changed
Remedy
*)
*)
Purge cooling air openings and cool-
ing elements if necessary;
Error is corrected automatically; **)
*)
*)
Acknowledge status code;
Check whether all conditions for
problem-free grid power feed opera-
tion are met (e.g., whether solar mod-
ules are covered with snow); *)
*)
Update inverter firmware; *)
As soon as the grid frequency returns
to the permissible range and the in-
verter is back to normal operation, the
error is automatically corrected; **)
Update inverter firmware; *)
