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 Service (see Section 11, page 30
).
202 to 203, 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 dis-
connected 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 Service (see Section 11, page 30
).
