Active power limit AC frequency
The inverter has reduced its power due to a too-high power frequency to en-
sure grid stability.
Corrective measures:
• If possible, check the power frequency and observe how often
fluctuations occur. If fluctuations occur frequently and this message is
displayed often, contact the grid operator and request approval to
change the operating parameters of the inverter. If the grid operator
gives his approval, discuss any changes to the operating parameters with
the Service.
