In Airstream Life Yamaha generators are discussed. Anybody have a EF2400iS which is supposed to be able to run the air conditioner. At 70 lbs. it might be the smallest unit to handle the job. They say it is quiet. Positive remarks in the article. Bilouie
I have one. Yes, it is quiet, at least as quiet as the Hondas. Easy start-one pull. At 70 lbs, it's not the lightest, but it is BLUE! Came with battery charging cables also. Good price-$1100 + free shipping!! All the way from the Midwest to Washington state. Cheapest I saw at the RV shows was $1225, so I think I did OK.
Cheers, Jeff

I had a Yamaha ef 2800i and while it would start and run a 13500 ac it was about all it could do. I can't believe a 2400 would be better. Have you concidered 2 in parallel ? The motorcycle store I used to worked for sold Yamaha products. I can tell you from experience they are a great product!! Yamaha customer service is over the top also. I have 2 --2000 Honda's I use
but only because I had them before the 2400's came out.---Pieman
Per Dometic, the 13,500/15,000 BTU AC or Heatpump REQUIRES 3500 watts to start under worse case conditions (ie hot, humid, high head pressure). The Yamaha 30iSEB WILL start the 13,500 and the 15,000 as it can deliver a full 3500 watts for upto 10 seconds and the Dometic Penguin only needs it for a about 1 second. The Dometic Digital Comfort Control Thermostat (heatpump 13,500s and all 15,000BTU units) also helps as it starts the blower first, lets it come upto speed (ie past the initial startup current) and THEN starts the compressor. So the startup loads are staged over time. Using this strategy, the odds are better that a genset slightly undersized will work most of the time, but again, if you ask owners of the Honda 3000eu models, they will tell you that from time to time, the Honda fails when the AC kicks in. SO, given the the Yamaha 2400w unit does NOT have the boost capability of the 30iSEB, I have some question about it's ability to always start the 13,500/15000 BTU units. BTW, the 13,500 & the 15,000 BTU Dometic Heatpumps pull exactly the same currents as they use the same compressor and blower. The 15,000 simply has larger condensor and evaporator coils. And as a side note, I own a Yamaha 30iSEB and everything stated in the A/SLife article is true.

Had one that got me thru a 10 days without power after Wilma last year. Always started no problem, ran a 12K BTU portable room A/C and a bunch of lights too. I didn't add up the totals, but I'm pretty sure that it was maxed out and still never quit.
Recently sold it and got an Onan 7000 Marquise that I'm converting to propane for the same purpose. BTW, you can buy a Yamaha already propane ready from www.yamaha-propane-natural-gas-generators.com.
I ordered one (EF2400iS) earlier this week and am eagerly awaiting delivery. I ordered propane/gas version in order not to have to fool around with gas while I am traveling - especially since my truck is diesel.
My AC is an 11,000 Btu so I think the gen will handle it ok. But Page and I don't find ourselves in hot places too much, anyway. We tend to head for the hills in the summer.
Well I'm really interested in the gas/propane model. Do you hook it into one of the tanks while the other is fueling the stove, refrig., etc.? Thanks to everyone for their thoughts. Bill
Bilouie---are you aware that when on propane the engine develops LESS power ,thus less electricial output??? Pieman
Officially, a propane gen set will gevelop 7-10% less output according to the manufacturers: Onan gas 7000 Marquise is listed as a 6500 for propane. But given the fact that you can NEVER get varnishing in the carb or plugs, IMHO it's a small price to pay for the better reliability, lower maintenance and starting qualities of a propane gen-set.
11k A/C units should be ok. 13k and 15k, most likely would need either a larger generator or two connected together. Worst thing for a compressor is to run in a browout type situation.
In addition to Lew's comments, I also like the propane feature because I don't have to lug around more fuel, if need be, I can use some of the nearly 60lbs I haul with me already.

My 30iSEB is a tri-fuel model. I run it exclusively on propane (gasoline as fallback only). I have a T-fitting on one of my 40# propane bottles in the A/S that I connect to an extension hose running to the genset. This extension hose was made by US Carb (where I purchased my 30iSEB) as I wanted a 20ft hose (ie custom due to longer length). I also have a 30# propane bottle (left over from when I changed the Bambi from steel to aluminum tanks) that I use whenever I want to run the genset without the trailer nearby. One additional advantage to propane is that you don't have to choke the unit when cold starting the unit.
