Grid fault
The power distribution grid has been
disconnected, the AC cable is damaged or the
line voltage at the termination point of the
inverter is too low. The inverter has disconnected
from the power distribution grid.
Corrective measures:
• Ensure that the miniature circuit-breaker is
switched on.
• Ensure that the AC cable is not damaged.
• Ensure that the AC cable is connected
correctly.
• 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.
