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).

Thoughts?

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.

Imho

It might be that the paralleled two Honda 2000 system may become passe' I yelled at a friend of mine for not asking me to help him with his new Honda 3000. He said he had no problem lifting it out of the truck by himself. It turns out that he purchased the new Honda 3000 " Handi ". I didn't notice it being much louder than the regular 3000, but much lighter, and I think that lower frequency sound that it makes is more tolerable than two Honda 2000.

Oops

I know that some like the ability to bring only one of their light weight Honda 2000 for trips when AC is not needed

BUT the Handi has half the run time as a regular 3000 due to half the fuel capacity. ( propane conversion might solve that issue )

sorry ..this must have been covered here a zillion times

The EF2400iSHC is a nice generator that will put out 20 amps all day and boost well over 30 amps for 10 seconds to start those big loads like a/c's. It's quiet, about 75 lbs with 2 handles. I can move mine around by myself, real easy for 2 people to move. It will also be around $500 cheaper than a dual generator setup.

He's completely wrong about the dual's not running even a 15k a/c. Yeah, probably trying to sell you something in stock, but not a bad alternative.

Stay away from those EF2800's. They are not an RV generator. I believe that is about the oldest model in the fleet and it is really loud. It's only purpose is that it will but out 20 amps, real cheap.

Let me put this way since he says to use "a single EF2400iSHC as a less preferred option to the EF2800i (lots louder)." Either there is no way he could possibly think you plan on hooking the 2 2000s in parallel because the 2 2000s have more power then either of those other 2 generators or he is lying to sell you something in stock.

In other words if 2 2000s can't run the air conditioner there is no way possible to run it on a single EF2400iSHC or a EF2800i since they each produce less power then the 2 2000s.

So no matter what he was thinking, he was wrong.

Well, I took the 2013 Sport to the closest Yamaha / Honda generator dealer and tested...

2x Yamaha 2k generators. Could not start AC in eco mode, and while in non-eco mode it could not restart the Air Conditioner after waiting 20 Minutes to try again.

Yamaha 2400 generator, basically the same story but it was quieter and is always in eco mode so it should run longer.

Honda eu3000i can start the air in eco mode, and restart in less than two minutes. Noise level is quieter than the two Yamaha's, and a higher tone than the Yamaha 2400.

I have to give thanks Desert Valley Powersports for all of the testing and a price better than the I could find on the internet.

Please explain to me.........

Hi, I do not understand why anyone would even think of trying to run the largest load of an RV [air conditioner] with generators in the Eco-Mode. To me, that is like pulling off four of eight spark plug wires to pull my trailer.

Note: my Yamaha 2400 has no Eco-Mode; Actually it has no Modes at all.
