Event number
Message, cause and corrective measures
101
Grid overvoltage (spot value)
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 Service.
102
Grid overvoltage fast
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 Service.
103
Grid overvoltage slow
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 Service.
