Arc-Fault Circuit Interrupter (AFCI)


The arc-fault circuit interrupter is deactivated by default and can be activated on the user interface.

The inverter is equipped with an arc fault circuit interrupter (AFCI). The inverter supports the Arc Fault Protection Equipment (AFPE) for arc fault detection and interruption. The AFPE protection covers the PV modules and DC cables of the PV system connected to the DC input terminals of the inverter. A detected electric arc causes a brief interruption of the feed-in operation.

An event message is entered on the user interface when an electric arc is detected. After a waiting period of 10 minutes, the inverter starts automatically and checks whether the electric arc is still present. If the electric arc is still present, the inverter disconnects from the utility grid again and the process is repeated. After 5 electric arc detections per day (24h), the feed-in operation of the inverter must be activated via direct or remote access via the user interface of the inverter. The configuration settings can be found in the corresponding section under Operation Arc-Fault Circuit Interrupter (AFCI)).

The AFPE detection has 24 channels and one input port per channel.
