So Jopopsy you say that the Yamaha EF2400iSHC for $1479.00 will run a 13.5 Air conditioner as well as 2 Hondas hooked up in parallel which would cost me roughly twice as much? Am I understanding that right?

The single Yamaha is rated to run a single 13.5 A/C. It does not have as many watts as two Hondas in parallel, but its rated at 400 more watts than a single EU2000i (and 400 extra surge watts on top of that). It won't be able to run, say, your microwave and A/C at the same time. But if you don't want the trouble of carting two, securing two (I'd lock them to your trailer), maintaining two, and hearing two? I'd deal w/ the inconvenience of microwave usage and let the Yamaha do its thing.

As w/ anything in life its give/take.

Want the most available amps w/ the biggest leeway in running your trailer like you're in full hookups? Get two EU2000is (companion and regular) and run them parallel.

Want the quietest generator you can buy, and still spin a 13.5k? If money is no object and weight is not a concern, the EU3000is is the clear winner as far as noise. I put a wheel kit on mine so I can roll it around w/ no problem. 2800 watts running, 3000 watts surge. Its a sweet package if noise bugs you.

Want a smaller footprint generator that can spin a 13.5 A/C, with room to spare (think fridge, converter, etc., some LED lights), and would be good for probably 90% of what you'll likely encounter? Take a hard look at the Yamaha.

Its all about what compromises you want to make. They all have them. You have to choose the ones you are willing to deal with.


*****Added*****

Also consider how often you need to run that A/C. If its only a couple/few months a year? You won't need that extra EU2000i, but that Yamaha can still be used fully since its beefier than the single EU2000i. And given its got more watts, it won't be running as hard as the single Honda since it has more capacity natively.

That EU3000is would likely be purring along all day long, growling to life briefly while you nuke something.

Just a thought.

Side note: A quick cliff-notes study in sound as it relates to the Hondas.

The EU2000i runs at 59db at rated load.
The EU3000is runs at 58db at rated load.

2 EU2000is running at rated load in parallel effectively create a single sound source of 62db.

What's 4db actually mean to somebody having to listen to them? My charts don't have the breakdown for 4db, but it DOES have it for 3db. 3db increase in sound is effectively a 23% increase in perceived volume.

The Yamaha runs at 60db at rated load. Remember, the rated load of the Yamaha is giving you 400 more watts than the rated load of the EU2000i. Meaning, unless the A/C is running it will probably be working less hard than the Honda. Which means it would be running closer to its 53db 1/4 load than would be the Honda.

FWIW.

Hey thank you for that info. Our thought is to use the generator to run the air conditioning only nothing else at the same time so the Yamaha may be our choice, By the way, what is your preferred method for transporting fuel for your generator and securing generator and fuel safely? Thanks

2 Honda eu2000i's.Honda's will hold surge wattage for 30 minutes,Yamaha's 30 seconds.

I have the same setup as you, but just one genny. Bought the boat tank and hose and some fittings from Walmart, and a couple of other fittings and JB Weld from the auto parts store. When boondocking, with no air conditioning, the 7 gallon boat tank will last me a good week or more. The tank in the generator is a pain in the butt to fill without overfilling.

Mine is the factory made berg system,bought it without tanks.I picked up the tanks from Walmart.

To fill the Internal gen tanks I use a 2 gallon gas can and a power aid bottle.Works great and no mess.

The only thing I don't like about the extended run system is sometimes it keeps the gen tank over filled and sometimes half full.

True. The Yamaha was never intended to run full surge for more than it takes to start a 13.5 A/C unit. That's what it was designed to do; basically be a EU2000i with more grunt that could also start a 13.5 A/C reliably.

Its all in the eye of the beholder.

When I had to tote the generator around with me I would bungie tie the genny and a 5 gallon fuel can inside the back of the pickup. Close to the rear window so its a heavier item and I didn't want to exasperate my weight distribution of the trailer by putting heavy items behind the rear axle.

As to securing the generator while camping? Check out this website:

Welcome to Lockitt.com

Everything you ever wanted to know about chains, density, thickness, resistance to cutting, etc. If you email them they will recommend a solution based on your criteria and risk tolerance. They had me outfitted w/ a nice beefy protector chain w/ a disc lock (normally used for bikes). The lock was great b/c the chain 'just' fit into it, and the lock had a 'screaming' function whereas if somebody moved it and did not unlock it, it would hollar at you at 110db for 30 seconds or so. Real nice feature.

I have the EU3000 and it powered my 13.5k AC unit in my old rig. Everything I've read says my generator won't have enough power to start my 15k AC in my 26RKS. I'm planning on selling on EU3000 and looking for a new inverter generator that has enough power.
