Grid fault
Grid fault
Cause and corrective measures
The line 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 line voltage at the
connection 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.
The utility grid has been disconnected, the
AC cable is damaged or the line voltage at the
connection point of the inverter is too low. The
inverter has disconnected from the utility grid.
Corrective measures:
• Ensure that the circuit breaker is switched
on.
• Ensure that the AC cable is not damaged.
• Ensure that the AC cable is connected
correctly.
• Check whether the line voltage at the
connection 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
