Generator selection

A question: How many BTUs is the A/C?

If it is below 13,500 BTUs, a Honda eu2000i can run it (although not it and the microwave at the same time.)

At 13,500 BTUs, it is iffish a 2400-3000 watt generator can run it, mainly due to the locked rotor amps. For this, I recommend two Honda 2000 units paired, or the above Yamaha 3000iSEB. Make sure to get the iSEB option with the battery boost so the generator can provide the additional 500 watts of inrush current.

At 15,000 BTUs, I'd definitely go for the Yamaha 3000iSEB or the Honda twins. Anything less, even "just" a 3000 watt generator won't hack it when the A/C starts up and demands its payment of 60 locked rotor amps.

As an alternative, you can use a hybrid inverter like Magnum Energy's or Victron's. This allows for a smaller genset, as the inverter and the battery bank eat the locked rotor amps.

I own a Honda Eu1000i for around the house emergencies, and I've owned two Honda EU2000i's and paired them. Much, much easier to lift a 48# Honda Eu2000i and get a pairing cable for the second Honda Eu2000i. They will loaf in eco mode, nice and quiet, once the AC is started up and running.

Honda motors have a lot of overhead... starting a heavy load won't make them stop running. Typical quality Honda product.

Having owned two EU2000i gensets myself I'd say absolutely ... 20% larger engine, much better sustained surge capability than the EF2000iS, and should you ever want to run a Progressive Industries EMS to protect your trailer's electrical system you won't be affected by the Progressive Industries / Yamaha Disclaimer.

Take this little bit of advise from a guy who tried the Generacs!

RUN, DO NOT WALK AWAY!!

They are completely overrated in what they say they can run! I had a total of 4 of them and could not get anywhere near the 14 amps they were rated. 11 was the best I could ever get. I sent a ton of information to Generac and the best they could come up with was to buy a big industrial open frame! Total waste of time!! I got pair of Honda's and now am happy as can be!! Will run everything I want with amps to spare.

Here is the thread on my ordeal. Read it and decide for yourself

Generac Beware

Good read. Thanks. Makes me wonder if I should be looking at a honda instead of the Yamaha. Even if I have to cough up some extra cheese. I hadn't even thought about powering a coffee pot. My wife has a percolator on the stove type deal that I swear is a left over from Lewis and Clark. I thought I was being a wuss wanting my AC and some of you guys are worried about your Keurigs.

Most folks use either Honda or Yahama. Honad EU-2000i USUALLY will not run a rooftop A/C (Some of the smaller high effiency ones perhaps but generally no)

The Yahama EF-2400i is just a bit more powerful and MIGHT get the job done.

The Honda, (And many other brands) can be paired and the pair WILL do the job.

I suspect today's Yahama's can also be parallelled.

A 3,000/3600 likely will (A 3600 is a full 30 amps by the way)

But they are a bit heavier than most folks care for.

Yeah, I was looking at weights. The Doubled up Yamahas look like a nice setup for flexibility. At my current age and shape, getting a 150lb generator out of the back of the truck alone is plenty doable, but certainly doesn't excite me.

Hondas and Yamahas seem to be super popular. Generac is a major brand in standby generators, and I know many people who have their large home stand by generators with great luck. So I was curious if the smaller stuff was worthwhile.

And most of our (if not all) camping will be done in NYS, mostly State/DEC campgrounds. Generators can be run something like 5 hours a day, usually between set morning hours then again afternoon/evening. I feel like that would be adequate.

I would suggest before you buy a Genny. IF you will be camping in campgrounds, like National Parks, and National forests, or state parks. You should research the rule. You may not be able to run the genny all night, or only for a couple hours a few times a day.

Now IF you are planning on camping out away from the world, like in the desert, or like that. Dosen't matter. You will be the only one to hear it.

If you must run the air conditioner I recommend something that can be paralleled as 2000 watts (1600 rated) is most likely too small.
