Grid fault
The line voltage or grid impedance at the
termination point of the inverter is too high. The
inverter has disconnected from the power
distribution grid.
Corrective measures:
• Check that the line voltage at the
termination point of the inverter is
permanently in the permissible range.
If the line voltage is outside the permissible
range due to local grid conditions, contact
the grid operator. Ask the grid operator
whether the voltage can be adapted at the
feed-in point or if it would be acceptable to
change the monitored operating limits.
If the line voltage is permanently in the
permissible range and this message is still
displayed, contact the SMA Service Line.
