Event, cause and corrective measures

101

Grid fault / Grid monitoring spot value (101)
The grid voltage or grid impedance at the connection point is too high. The inverter
has disconnected from the utility grid.
Corrective measures:

• Check whether the grid voltage at the connection point 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 approve changes to the
operating parameters of the inverter.
If the grid voltage is permanently within the permissible range and this message is
still displayed, contact the SMA Service Line.

102

Grid fault / Grid overvoltage fast (102)
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 approve changes to the
operating parameters of the inverter.
If the grid voltage is permanently within the permissible range and this message is
still displayed, contact the SMA Service Line.

202

Grid fault / Grid undervoltage fast (202)
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:

1. Make sure that the circuit breaker is switched on.
2. Make sure that the AC cable is not damaged.
3. Make sure that the AC cable is correctly connected.
4. Check whether the grid voltage at the connection point of the inverter is
