Roadtech, yes there is about a 15% reduction running on propane.

Curious, do you have a source for that info? I have not used my converted generator enough to really have an informed opinion.

I don't see how the output of the generator can be effected by the fuel you run? The engine part of the generator is used to turn a generator unit. The output of the generator is bases on RPM not torque out put. as long as the engine can achieve the max rpm the output should be the same?

A gallon of propane does not contain as much "energy potential for the internal combustion engine" that just means a gallon and 1/2 is needed to do as much work (btu's) and a gallon of gasoline. The generator should still produce the save watt output, just might use more propane than gas over the long run.

AWCHIEF, don't have info in front of me, but worked for Cummins/Onan for 23 years. They used the figure of 15% reduction in power because natural gas and propane does not burn as hot as gasoline. Examples of Onan:
gas 2800 watt microlite is a 2500 watt on propane
gas 4000 watt mircolite is a 3600 watt on propane.
They are the exact same models other than the carburetors.
You can probably find it on their website.

Joe,

Your line of reasoning sounds correct and I think the same way but in the literature for the factory dual fuel generator I own it specifically warns there is a reduction in wattage when using propane.
Maybe torque is a bigger factor than we think in wattage. RPMs affect the voltage and hertz more?
You got me curious.

You're running your TV on diesel and, already have propane tanks. Unless the drop in power output would be a problem, spend the money and go with the propane model. A benefit of propane over gasoline is that the shelf life of propane is measured in YEARS, not months.

Gary, thanks for the info on power reduction.....I do not notice any real difference and have been using the propane for about a year....I also carry a 20# tank, but can also use one of the 30# tanks on the AS. Also, I have found that if you use both Honda 2000's to run the AC, you need to use a separate tank and regulator for each one. Tried to use a spliter off one tank but could not keep them running. Assume they were not getting enough fuel?
Andy

Does that mean you couldn't use the Airstream front propane connection to run two 2000's?

We have not had any problem running 2 propane Honda 2000s off of the propane port using a "y" splitter hose from Genconnex. Joe

Andy, on mine I run straight off of the bottle. Joe D the output of a generator is calculated with horsepower and of course the size of the windings and armature. So if fuel is not burning as hot thus reducing horsepower you lose wattage. Yes the engine is still trying to run the same speed but the power is not there to keep it there. Most people will never realize the loss until you are trying to load the generator to max load. One other thing to consider is what is the rated load capacity. Advertisements are usually peak load.......

Thanks, so as the load puts more resistance into the windings the loss of explosive power from the propane can't over come the resistance and maintain the RPM's needed to produce max out put. Makes sense.
Always a good day when you learn something new.

Gary, are you using an inline regulator to each Honda?
I had a splinter on the tank, then two hoses with a regulated on each hose.

There's a long thread in the generator section discussing 'actual' experience running two propane Hondas and what he said above ^ is the consensus. I ordered a Genconnex propane Honda 2000 last week and will get it on Wed. Am planing to run it off the low pressure bbq port.
