Code Description
240 AFCI trigger
241 - 242 AFCI trigger
Service Class 3
Class 3 comprises status codes that may appear during feed-in operation and that do not
cause a permanent interruption of the operation of feeding power into the grid.
After automatic disconnection from the grid and waiting for its conditions to return to those
stipulated, your inverter will try to resume feed-in operation.

visible for 4 seconds, then 241
AFCI triggered. To continue
the process, press Enter 2x
(first 242, then process is con-
tinued)
