Running AC with a Generator

I'm looking at purchasing a small 3000W Yamaha or Honda Inverter. I have a 7500 Generator but its loud enough to wake the dead.

The inverters and nice and quiet that won't disturb everyone around me.
My only concern is the Aspen Trail has a 13.5 BTU Air Conditioning system and 35K BTU Furnace.
Will it run the AC or Furnace without any problems ?
We're planning a road trip and may have to stop a couple times before we hit some campgrounds, and I don't want to have the wife and kids roasting inside the camper.

I assume the only way to power the AC unit is via 120V or a Generator/Inverter.

Thanks

Watts divided by Volts equals amps


3000/120=25
Does your ac pull Less than 25Amps at startup? it will be on the name plate of the A/C unit.

3000 watt gen should run the 13.5 kBtu air con quite well. The furnace runs on 12V DC and won't draw from the generator 120V AC. Yes, the gen 120V AC will supply power to the converter which will provide 12V DC for battery charging so in a round a bout way it may pull some AC load. But the furnace blower fan is pulling something like 7A DC which would be like 70 watts of AC load.

I looked into the Honda/Yamaha buzz when we had our 2014 Outback 250 RS and saw a video on youtube with a guy running a 2000 Hyundai generator and hard starting his 13.5 AC with no problem... so of course I looked a bit deeper and for the price...$525.00 as opposed to the $1000.00 big boys and went with the Hyundai... It has 2200 peak watts and 2000 running watts which will start the 13.5 AC with no problem... One question to ask yourself also is how often will you be running a generator? $1000.00 seems a lot to spend to use on occasion.

This to me is a better deal. Can be found cheaper than this, I did.

The Yamaha or 2 honda 2,000 are the way to go If you check back on the guy with the Hyundia it brike shortly after.we talked to a guy who had the yamaha 3,000 & it handled the A/C no problem.

A single Honda 2000 or Yamaha 2400 may run the AC; however, it will be marginal even with a hard start capacitor installed. And the higher in elevation you are, the less power the generator engine will be able to provide which means it less electricity. Our Yamaha 2400 (with hard start capacitor installed) will start and run our air con at home on a cool day at 4500' above sea level. But at higher elevation and/or high temps it is hit or miss (and more often miss). That's with w/h and fridge on propane and converter switched off. Go with a single 3000 watt or multiple 2000+ watt in parallel to be sure you have the power to run the AC under most any circumstance.

We have a Honda EU3000 and have run our single 13.5 BTU AC a few times on it. It handled it for sure but a few observations.
1) It burned some fuel. Nothing over the top but it certainly is working a lot harder than normal.
2) It cools but I don't think it cools as well as when we are plugged into shore power. Not sure why this is? Maybe the 3000 is "just" enough to run it?
If I had it to do over again I'd do (2) EU2000 for sure. 90% of the time we'd only need one of them as we camp mainly in the mountains and the EU3000 is HEAVY! It requires 2 of us to load/unload it from the basket I have on the rear. A couple of 2000's I could keep in the "bear cave" up front.
I'm a big fan of the Honda because they are quiet! We use ours a ton and we've camped next to people with "contractor grade" generators. They are insanely loud!

We have a basic generator - similar to the Harbor Freight ones. Works everything except need to turn off the 13.5 AC when using the microwave.
