Seems like I saw something regarding an incident with a Parasound and protect mode, last month, under other circumstances. No idea the model, I'll try to find it.

The fridge is a worse scenario worth the time/expense IMO, to remove to a separate breaker.
That's a pretty big draw, I'm still trying to understand our issue after having our main panel replaced (new) and a new separate subpanel on our 55 yr. old home (to add a 2-story garage). Even though we had the house AC removed to a dedicated line/breaker at that time; it can still dim lights in the house, when the compressor kicks in
