Event 701

Event message:

• Frequency not permitted

• Check parameter

Explanation:

The grid frequency is not within the permissible range. The inverter has disconnected from the utility grid.

Corrective measures:

• Check the AC cabling from the inverter to the feed-in meter.

• 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 his approval, discuss any changes to the operating parameters with the Service.
