Generally speaking you only want small appliances, TV's etc to run off an inverter.
It would be easiest there for a small inverter, but most coaches only have a 50 Amp DC breaker between the batteries and converter and wire sized for that current, so that would be a bad idea for any inverter bigger than about 400 watts - and that's pushing it as there are other DC loads to consider.

That is a point. Mine is 1200 w but I don't come anywhere near to drawing that. It's good idea to feel the battery leads when loading them down to see if they are warm. I don't try to run a microwave or anything like that. if I want to do that i start the genset. The inverter is handy for powering a TV, my cpap, computer & stuff like that. I had a heck of a job getting my fridge onto a separate 120v run as its on the other side of the RV and was looped to a couple of other sockets, including the one powering my TV. That is one appliance you do not want running off an inverter unless ist A/C only.

What appliance are you referring to? A TV? That's the primary purpose of adding an inverter in most RVs: to power the TV without running the generator when not connected to SP.

no, i meant my fridge & TV were on the same run,so I had to separate them out so the TV was on the inverter, but the fridge was not.

So the absorption fridge is the appliance you never want to run off an inverter? Better not tell that to all the propane safety advocates whose primary purpose for an inverter is so they can run their absorption fridge underway without using the "dangerous" propane.

400 watts of resistive load is the perfect use for a MSW inverter.
