3100w Champion inverter enough?

26DBS Not sure which A/C i have, the standard option i believe.. I need a generator for a short trip next year. I can get the 3100w champion inverter refurb for $550. Is that going to be enough? Mainly A/C. I've never had a chance to use the camper yet besides plugging it in a couple days outside of the garage.

I have the 3400w duel fuel champion inverter. When I run it on propane it is rated at 3060. With that I have no issues running my 15k btu Coleman mach3 a.c. as well as my inverter and tv. Beyond that I start turning this off but it was able to do this in eco mode with a short stutter to high speed when the AC started. My AC already had a hard start capacitor. You may need to add one even for a 13k btu A.C. they are cheap ($10ish) and simple to wire up by watching YouTube videos.

I believe the gas side engines are all the same for the champions.

That is a good price and I would jump at that. Another option is the harbor freight which seems to be stepping up and is about $640 at 3500w.

If you get the champion and plan to use above 3500ft then email them for the rejet kit.

I don't plan on using it at that altitude. So they have two gens, same output.

3100w startup
2800w run

For $550 the one comes with GFI outlets with covers but no automatic voltage regulation but is parallel capable.

The other without GFI outlets has automatic voltage regulation and is not parallel capable. That one runs $595.

I emailed them about it.

I read on another forum where someone had an issue using the GFCI outlets when plugging the camper into them. We've had several reports of the GFCI outlet tripping in a house when a camper is adapted and plugged into a GFCI outlet (since the camper has GFCI outlets inside, they don't play nice with GFCI's plugged into other GFCI's) so it's very possible it could happen with the generator as well.

With that said, you mentioned wanting to use the Air Conditioner so you would only want to use the 30a R/V outlet anyway. That one is protected by a circuit breaker but not a GFCI.

As for load, I believe the 3100 will adequately handle a 13.5 k air conditioner with no issue. It might be on the edge of handling a 15k.

I have the 3100 and can power my 15K A\C unit a light or 2 and the tv with it. I have to put the fridge on propane or the draw is too much, but I like the 3100 and recommend it.

I was mostly concerned about the voltage regulation. I'd rather save the $40-$50 if there's no difference.

I'd take regulated over non-regulated any day of the week.

I believe that to be pretty important, especially on a generator.

Wild power swings isn't good for any load in an R/V.

Voltage regulation is very important especially when operating equipment like a AC with high amp draw. If the voltage drops off the amps go up and you either blow a breaker or burn your compressor. One of the biggest killers of AC units RV or household is low voltage.

Should be more than enough. If the a/c starts hard install an inexpensive capacitor hard start kit. My Honda EU2000i will start and run my 13.5 a/c with the capacitor. Once you get past the start it is smooth sailing, doesn't take a ton of juice to run.
