Preventing Feedback loops

I have a Victron 2000/12V/80 and am concerned that if it’s output goes to a load center in my RV and the load center is connected to it’s input what prevents a feedback loop?

It will try to synchronise and get a weird output in frequency or voltage. (And sound)

It may then switch off or it might reject the input. It depends on what and how the connection is made.

The best situation is prevention - the one where it doesn’t or can’t physically happen. (Add an isolator or something that can be physically switched off on the input as an extra precaution)
Other way would be a changeover switch so unplugging and plugging does not happen but rather an actual path change.

got it, Thanks for your help. It appears the best solution is to physically remove the possibility of a feed back loop. Having said that, I would still like to know how the Vicron internal transfer switch works.
