Another Generator Thread - Sorry!

Short Version:

If I get two Yamaha 2000s, can they reliably run the 15k AC? Is it twice as loud as a single generator? Do they hold enough gas collectively to run the AC throughout the night (6-8 hours)

Before I start, I have looked through all the generator threads (I can find) on this forum. I've got a new 29.5BHDS with a 15k AC.

Originally, I was going to get two of the Yamaha 2000s to power the AC. Then I wondered if it'd be quieter to get like the 3000. I saw someone else with an added capacitor (I have zero faith in my electrical abilities) ran theirs from a 2400.

I want to keep the generators in the back of my truck for use on stops during travel. In Texas, without AC, your face melts off. Running the Microwave is not necessary, and the water pump/heater would be nice (but again - not necessary). I just want the AC to blow cold while we sleep and not get dirty looks from parking lot neighbors if we can avoid it.

Thoughts? Thanks!

Too loud in my opinion. They're going to be running at a pretty high rpm to satisfy an a/c load. I wouldn't want to be your neighbor in such an instance.

Ode to the Forum Moderators

May the Mods grant me the serenity to accept the opinions of those I cannot change,
the courage to offer valid input to those who are open to another way of thinking,
and the wisdom to shut myself down whenever I get too in love with my own misconceived brilliance.

If you get the pairing cable, two 2,000 watt gensets will give you 4,000 watts. More than enough to run a single A/C unit.

Run time on the fuel tanks? Probably not much over 4 hours.

Noise level? Check the published specs.

If you are in a crowded campground during a heat wave (we were June 11) everybody will be running their gensets and A/C.

I've looked into this as well and found from my research that you can actually power the AC with a single 2000 generator if you have a soft starter installed.

Here is a youtube link of it

and here is the link to the website of that actual product. https://id144248.webhosting.optonlin...&products_id=4

Also I just purchased a Honda EU3000 this week and I'll be also installing this EasyStart device to help me power up my 15K ac unit.

Go Honda eu2000i and eu2000i companion.You can get a extended run fuel system.They do make the extended run fuel systems for the Yamaha's.However I don't know how effective they are,The Hondas have a internal vacuum driven fuel pump.Here is my setup total is 14 gallons of gas(1 gallon per internal tank on each generator and 2 6 gallon boat gas tank).Lots and lots of run time.I also have then 15k btu a/c with a soft start capacitor.They run it with power to spare.

You may find the following recent JOF thread of interest on the subject of a single Yamaha 2400 and a 15k A/C:

Honda EU3000iS

These 2 solutions will work great.

1. Use 2 EU2000i Companions (The Companion has a 30A outlet)
Pros: 45.6 lbs each
Cons: .95 gal tank
Runtime = 3.4hr @ rated load 8.1 hrs @ 1/4 load
Takes up more space.
2. Use an EU3000iS
Pros: 3.4 gal tank
Runtime = 7.1 hrs. @ rated load, 20 hrs. @ 1/4 load
Cons: 131 lbs.

I'm using option 2, the Honda EU3000is. Runs the 15K AC all night and then some. I will be installing the hard start capacitor as when the AC starts now it sucks the voltage down too much.
Bottom line is what's more important to you?

I run the 2000 Honda great unit I have the new Jayco BHDS 29.5 I've decided to buy another 2000 run them together for my air conditioner my reason is they are easier to carry around and cheaper to buy then the 3000 plus for how much I'll be running the air it's not work it to spend that much on a 3000

If it is your intent to leave it in the truck, the QUIETEST of them all is a 3000 Honda. Has a 4 gal tank that allows you to run in excess of 24 hrs between fill ups. Far quieter then any two of anything on the market. The down side is that it weighs in at 140 lb. Will run 15000 AC with no problem. Absolutely bullet proof (if you keep the mice out of it)
