My twin Honda EU3000is Generator Install

[blue_goose]

I haven't looked, but would think there should be some on the used market.  Lots of motorhomes that were taken off the road that had good generators.

I have a Yamaha ISEB 3000 inverter model that I loved. I used it for 11 years and put many hundreds maybe thousands of hours on it. Then it quit making power one day and I could not find any one even at the so-called service centers that knew how to fix it. I was told the same thing by 4 service centers. "We work on Hondas all the time and can fix them but we have never had a Yamaha in here broken even though we are a service center" I do not know if this is because there are a lot more Hondas or because they give more trouble. I bought a service cd and trouble shot it my self but have not fixed it due to the parts cost. I am keeping my eye open for one with a bad motor.

Well, after much deliberation, I purchased two of these today along with parallel cables. Don't have the time to explain fully right now, but sometime when we are more settled (January) I'll be obtaining or making a true 50aml parallel kit/receptacle for these things. For now I am happy to have a nice couple of gennies:

     Nice looking unit, Scott.  Does the true 50 amp parallel kit give you 240V or just increase the amps at 120V?

I am just curious how you balance the load on the 2 generator sets feeding 1 entrance lead,I know how it is done on the bigger diesel powered sets but not on the little Honda's you have a answer Dave M

[Scott Crosby]

The little gasoline Honda generators have a special plug that links them together and since they are inverters that convert DC to AC it easily matches the voltage and hertz to,double their amp and watt output on a single line ... If it was just a generator the engine rpm would cause problems with that but that's how they do it Clifford.  They are slightly different models available too as one is a slave and one is the source.  Not sure if you have to have the slave though but it's usually a slightly different price when I've looked at them.

For the record Dick - "somewhereusa" had that Yamaha inverter generator catch on fire while he was using it.  Internal fuel leak under the casing caused it.

Those Honda 3000 inverter gensets are truly excellent quality. If you keep the oil changed frequently, you should get near 5,000 hours out of them
I had the Onan Emerald III 6.5 commercial (had a PTO [power take off] shaft out the back of the alternator) that ran at 1,800rpm continuous that I used on my truck. My first one went 12,000 hours before quitting. Rather than overhaul it, I just bought another one. I believe those units are still available for commercial use since the phone company and others use those generators to power a hydraulic pump for their man lifts. I used the PTO to power an air conditioning compressor for the A/C in my sleeper when parked. Good Luck, TomC

I know what the link cable is it's a diode cable so to me there has to be something else inside each generator,I am guessing that is why they want the 2 the same model when using the cable.
I think I would split the generators into 2 different circuits 1 for ea generator and forget the link.
You see a lot of generator fires with the tank mounted on top of the engines on all brands except on the cheap ones they don't last long enough to rust.This crapo gasoline we buy now eats the tanks up.I have a 11hp Honda on my power washer and 9 hp on a compressor both tanks are rusted through in 6 years and Honda wants a fortune for the tanks    

[eagle19952]

wouldn't you be better off replacing the tanks with outboard motor tanks...

[Scott & Heather]

So yes, there is a parallel cable kit to link them together as was already mentioned. It does not give me 240v but rather 5600 watts of continuous 120v burstable to 6000 watts for 10 seconds for starting loads. These things are insanely quiet. As in, I would happily violate no gen hours in a state park if I had to because you literally cannot hear them run in Eco mode. They don't both fit quite right in my condenser bay so I'm working on mounting them on a hitch platform that locks. Hopefully will be on the road by this evening testing out the whole shebang

I looked into this once, this is what I got.  The honda gennies look for external AC on startup and synch to it, with two generators you kind of have to start one first so the second one synch's to the first one.  People have run them in parallel with other types of generators.  The cable is nothing more than a pure parallel cable, nothing else inside it, jigged up so it is safe  (you don't have a cable with two live male connectors).  They have a "companion" model 2000 watt generator that has a built in 30 amp plug so you don't need an external adaptor.  In the straight Honda world they only want you to parallel the same size generator so they load share 50-50 just naturally.  I don't know that happens if you load share a smaller generator with a larger one and the load exceeds twice the rating of the small one.  It might pop a breaker.

Or convert them to propane?

I converted my little emergencies-only generator  -  it now runs quieter than before, doesn't make an exhaust stink, and starts reliably on the third pull every time.   Now I don't worry about gasoline going bad and gumming up the carburetor, or gasoline lines or the fuel tank leaking.   Well worth it.

Our generator is a Honda 6.5KW running on propane, built in, (came with the bus). with remote start upstairs. Sure is sweet. Yea a diesel would be better, but this came with the bus, and will do quite well for a long time. It is reasonably quiet, clean, doesn't burn too much propane, nothing wrong with it.

I went with the honda eu7000is gas fuel injected  gene and could not be happier . on full load it runs a 59 db - 61 db that is quieter then riding inside a mercedes  benz at 65 mph with all fans , radio off . with the eco mode on it is as quiet as 52 db . I have ordered a key fob style remote start for it so I can start and stop it from inside the coach .

and it fit in my condenser bay on a roll out dwr with a exhaust that goes to the outside and a fan that removes the convection heat from the open bay .

    Yeah, that looks like a nice setup, Dave.  Is there a way to do "auto start" when batteries drop to a specified voltage?  Is it air cooled, if so, what's the warmest temp outside that you've run it?  What fan did you use and how did you calculate its size?  How is fuel usage - a full tank in 6 hours would seem like a lot of getting up in the middle of the night to fill the gas tank -- plus carrying a lot of gas/jerry cans.  It sure is nice that it can supply 240V though. less than 300 pounds for a 5000W unit is great, and that noise level can't be beat.  I'm assuming that you aren't using the wheel kit -- what did you do for isolating the feet?  I see a couple of people selling them on Amazon for $3999 but $269 for a fob remote kinda pinches!
