Dual Generators

Well, I had ordered a couple of Yamaha EF2000is generators with the propane conversion a couple weeks ago. When I called to check on the order, they were back ordered and the salesman asked what I was using them for. When I sent the 13.5K BTU AC, he said they wouldn't run it, and that someone had problems running a 12k BTU.

This has me confused, because I don't think I have read of anyone having problems running a 13.5k BTU AC with dual Yamaha's or Hondas.

He recommended a single EF2400iSHC as a less preferred option to the EF2800i (lots louder).

He wants to clear a back-order by offering you something he has in stock.

You have a better idea of what you need than he does. His statement about peoplewho have had problems— people you don't know and can't talk to about their so-called problems— means nothing.

Stand firm and tell him you want the gensets you ordered.

Is he recommending a higher priced option? I have a pair of Hondas, the dealer here told me my "idea" of parallel was impossible, until I showed him the Honda website printout.

He had the cables and 30A adapter right in the store. His route would have been only $45 more dollars, but it made me suspicious of his motives so I bought them @ Camping World, along with the cables.

I have a single yamaha 2000. it will run a 13k btu ac on it's own (not in eco mode), but nothing else. Two of them should have adequate amperage for that ac and some other appliances without problem.

You can purchase all you need on Amazon.

The sales guy is either trying to bait you to a different choice, totally incompetent or badly trained in his products. Two 2000w gennies run in parallel will have absolutely NO trouble running your AC and anything else you want to in your rig. That's what we do...

A pair of Honda 2000's run my whole Airstream with a 13,500 btu AC. In addition they will handle the refer in my house on an extension cord at the same time. The salesman you talked to obviously suffers from cranial rectumitis. This disease is very common among salespeople who sell technical gear that they know absolutely nothing about.

At best the salesman thought you planned to run the AC on 1 of the 2000s, NOT both.

This is an excerpt from the last email, I had mentioned that he was the first one that said that they would not run a 13.5k BTU AC. I think the they was pretty clear....

I said they will not run a 13000btu ac
Oh well, he has placed doubt in my mind. I guess if I decide I still want to go this way I will just buy locally and test prior to ordering propane conversion parts if I still want to go propane.

Just look at the specs - a single generator will peak at 2000 watts and 16 amps. Normal run is 12 amps and 1600 watts.

A 13k air conditioner peaks at 12 amps and 1500 watts. It should settle around 8 or 9 amps after start. Starting the AC is the critical point. Depending on the loads from other devices - like your refer, CO detector and converter, it may or may not trip. A microwave is an easy 12 amps, so starting that would definately trip with the other items running.

Geez, that's bad news... Let him know that my 2 Honda 2000's run my 15,000 btu AC unit and that you need to consider switching to the Red brand...

Me's betting he will recant and sell you a matching pair of blue generators.

Hi, I have the Yamaha 2400 and it will run my 11,000 BTU air conditioner, my refrigerator, and converter at high altitude; There is no reason that two 2,000's wouldn't run what one 2400 will. [find another dealer]

The Honda parallel kit for their master and slave 2,000 watt units are sold as supporting the 30amp power load of a trailer wired for 30amps. Running the A/C and then turning on a microwave and a hairdryer will stop the show. But it would also do so in a house with 30 amp service.

The typical challenge is the surge associated with starting the A/C when the thermostat decides it wants more cooling. What all was running while the A/C was in actual operation at the lower running current draw, could be too much load for the current in-rush when the A/C cycles back on.

This is not an Airstream specific issue as my son's SOB often pops the 30amp mains when one of the gals turns on a hairdryer or too many lights.
