I don't want to get into a P**ing contest with you however, this is what my Generac (see Sig) Installation manual states in a chart that compares the various models of Generac RV generators.

 NP-50G (gas) output- 5000W/120V/41.6A
 NP-50LP (propane fuel, same generator, engine etc) output- 4500W/120V/37.5A

Now unless there is something about the "new math" that I don't understand, that is a 10% reduction in output.

I agree that for the same output the LP generator will consume 10% more fuel.

May you have "smooth sailing and following seas"!

Richard

I wondered if I could be the only one that wanted the EU2000 and a longer run time. Now.... I wonder if I can run tandem generators off one large tank. I will call Wise to see what they say. Thanks for your help!

Richard,

No contest is required. The unit that is made for propane has been derated by the manufacture. It may have the same engine and gen, but the controls and fuel delivery are different.

The machine will consume what fuel it needs to generate and satisfy the electrical demand. Propane has less energy per pound than gasoline. So for the same power demand it will take more propane than gasoline.

It is an energy balance thing.

If it takes 10 pounds of gasoline to generate 16 kW, then it will take 11 pounds of propane to generate 16 kW.

Sorry, I didn't mean to ruffle anyone.



FWIW, I hate these gen sets in campgrounds with electricity. There is always some knothead who won't plug their rig into the campground power and insists on running the noisy gen set next to my camper. Funny thing happens around 2 am, about the time I'm fed up with the noise, the fuel shut off valve mysteriously moves to the "off" position. Then silence returns. The next morning the knothead wonders how it ran out of fuel in the middle of the night, while fuel remains in the tank. I just play dumb and remind him about the campground power.

and i have a 3000 and 2 2000 eu's that i can use.

and i justed tee off my 1 36 gal fuel tank and run the hose down and tee it into both carbs on the little hondas,

now they will run forever,
i dont even use their tank at all !

i have also permenetly mounted a 3000 for a buddy where i added a 40 gal fuel cell and mounted the pannel inside ,
and ran a new exhaust and the thing just works great .

I use 2 honda EU2000's. It is pretty simple to set up a larger gas can system. I bought 2 new Honda gas caps, removed the vents from them, epoxied in place a small brass straw (for lack of better description) in each cap, get a couple of feet of clear tubing (gasoline use approved) get a tee for the tubing. Connect the tubing to the 'straws' tee them together, put the bottom run from the tee into a full 5 gallon gas can, the vacuum generated from the fuel level decreasing in the Hondas, will pull fuel into the Honda gas tanks. Then you just monitor the one 5 gallon gas can, and be sure to shut down and check the oil level once a day.

Thanks for the idea of making the aux. tank. It sounds exactly like one being sold for $139. I am sure you made yours for MUCH less. I already have a spare plastic outboard motor tank. I am thinking that I can cut the outboard rubber hose that came with the tank and connect it to the tee you mention. Then I could just use the std tank to hose disconnect to remove the tank for refilling. Do you think that the new Honda gas cap vent holes could be tapped and then install screw in hose barb fittings? Does that sound like it would work. Thanks again for the idea of making the tank mod and saving $ (to be used for diesel fuel, of course)

Inverter generators

We use a Honda EU2000 to run our hunting camp. The great thing about the Inverter generators (Honda and Yamaha) is that they all have Eco throttles and only run at a speed that the load requires. The EU2000 runs our camp for 9 hours on the 1 gallon that is in the tank. We have used a extend-a-tank for at least 10 years. It will run for about 3 days without a refill. We always change the oil each time. When we bought the Honda, the dealer told us it would pay for itself in just a few years and he was right. I just wish that they would make an inverter generator for motorhomes.

I made up a siphon for my Honda that I hook up to a larger gas can. I drilled a 1/2" hole into the center of a lawn mower gas cap. This allowed me to keep the original gas cap as it is vented, this allows me to use the gen with out the larger tank. The Honda lawnmower cap was also a lot cheaper than the generator cap. I used air tool fitting that I threaded into the hole I drilled, then connected a rubber hose from the air tool fitting. The hose just goes into the gas can. The key to making this work is the connection to the cap must be air tight and the on board gas tank on the generator needs to be filled to the top. As the generator uses the fuel it draws fuel from the larger tank (the vent). The whole setup cost about $20. The commercial unit is over a $100. Wish I had a picture but the fitting is at my cabin.

I don't know how to post pictures on this site. So send me a PM with your e-mail and I will send you pictures of my extended tank setup for my two 2000. It works great and only cost me about $30.
