11.1 Event messages
11.1.1 Event 101
Event message:
• Grid incident
Explanation:
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.
11.1.2 Event 102
