Grid incident

The grid voltage or grid impedance at the connection point of the inverter is too high. The inverter has disconnected from the utility grid.

Corrective measures:

  • Check whether the grid voltage at the connection point of the inverter is permanently in the permissible range.

    If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator. The grid operator must agree with an adjustment of the voltage at the feed-in point or with a change of the monitored operating limits.

    If the grid voltage is permanently within the permissible range and this message is still displayed, contact the Service.

301

Grid incident

The ten-minute average value of the grid voltage is no longer within the permissible range. The grid voltage or grid impedance at the connection point is too high. The inverter disconnects from the utility grid to maintain power quality.

Corrective measures:

  • During the feed-in operation, check whether the grid voltage at the connection point of the inverter is permanently in the permissible range.

    If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator. The grid operator must agree with an adjustment of the voltage at the feed-in point or with a change of the monitored operating limits.

    If the grid voltage is permanently within the permissible range and this message is still displayed, contact the Service.

302

Active power limit AC voltage

The inverter has reduced its power due to a too-high grid voltage to ensure grid stability.

Corrective measures:

  • If possible, check the grid voltage 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.

401

  • Check the grid connection for significant short-term frequency fluctuations.

501

Grid incident

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

Corrective measures:

  • If possible, check the power frequency and observe how often fluctuations occur.

    If the grid operator gives his approval, discuss any changes to the operating parameters with the Service.

507

Active power limit AC frequency

The inverter has reduced its power due to a too-high grid frequency to ensure grid stability.

Corrective measures:

  • If possible, check the power frequency and observe how often fluctuations occur.
