Hi,

I'm preparing to install solar on my 19ft RV. I have 4x 100W panels, a 150V/35 amp solar charge controller, 3x 100 ah lithium batteries, and a 2000W inverter/charger with a built-in 50 amp transfer switch (the victron multi compact).

My question is regarding the 50 amp transfer switch. The RV I have only uses a 30 amp system. Will this transfer switch work when I plug into 30 amp shore power? And will it also work if I use an adapter and plug into 50 amp shore power? (I plan to wire the shore power line into the "AC in" part of the inverter).

I'm thinking that plugging into 30 amp will be ok, and that the 50 amp transfer switch will allow the 30 amps to travel on in as it should. However, I'm concerned that if I use an adapter and plug into 50 amp (I'm new to RVing, and this seems like something folks have to do now and then), this will allow 50 amps into my system and flip a breaker somewhere or worse. Is that right? Or does the adapter restrict the amperage to 30?
