Arc-Fault Circuit Interrupter (AFCI)
The type label of your inverter indicates whether your inverter has AFCI.
The arc-fault circuit interrupter is activated by default and can be deactivated on the user interface.
If the inverter is equipped with AFCI function, it supports AFPE (Arc-Fault Protection Equipment) for arc 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 AFPE detection has 24 channels and one input port per channel.
