Event Messages

Event number Message, cause and corrective measures
101
Grid fault
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
301
Grid fault
The ten-minute average value of the grid voltage is no longer within the per-
missible range. The grid voltage or grid impedance at the connection point is
too high. The inverter disconnects from the utility grid to maintain power qual-
ity.
Corrective measures:
• During the feed-in operation, check whether the grid voltage at the
401
Grid fault
The inverter has disconnected from the utility grid. A stand-alone grid or a very
large change in the power frequency was detected.
Corrective measures:
• Check the grid connection for significant short-term frequency fluctuations.
User Manual
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.
