Error number Display message, cause and corrective measures
101 to 103 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 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 the SMA Service Line.
202 to 205 Grid fault
The utility grid has been disconnected, the AC cable is damaged or the
grid voltage at the connection point of the inverter is too low. The inverter
has disconnected from the utility grid.
Corrective measures:
• Make sure that the circuit breaker is switched on.
• Make sure that the AC cable is not damaged.
• Make sure that the AC cable is correctly connected.
• 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 the SMA Service Line.
