Inverter /breaker noise

Markfarver

2021 400, I have a fan motor running while on shore power that has not happened before. Not sure if there is anything to do here?  Fan noise coming from breaker/fuse pannel

The converter is the brown box that you hear the fan running while on shore power. It is charging your battery and the fan will run until the battery is fully charged. It’s normal.
