Event 507
Qualified person
Event message:
Active power limit AC frequency
Explanation:
The inverter has reduced its power due to a too-high grid frequency to ensure grid stability.
Corrective measures:
If possible, check the grid 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 approval, discuss any changes to the operating parameters with the Service.
