What type of fuel were you intending to use? Gasoline, Propane? Best fuel from a dependability point of view, if you are not at the cabin full time, would be propane vapor. Generators de-rate in wattage output as you get higher in altitude due to horsepower loss at the engine. They de-rate some on VAPOR fuels. What altitude is this cabin at? Can you post a picture of the generator set AND the model and serial number? If you have it mounted in an enclosure, you need to ensure, depending what type of air cooling system the set has, that the generator has ample COOL intake air and a dedicated exhaust cooling air access so the two don't readily mix to prevent over-heating. The enclosure definitely needs to be critter proof from little four legged type rodents. They JUST LOVE to nest in Onans, chew on the wiring and PEE on the whole set! To run your 12 volt, 30 amp @ 12 volt charger, you might be much cheaper, if you have NO other power needs, to use a small Honda 2000 inverter generator to run the charger. It will do the job with a lot less fuel consumption than the Onan.

I really appreciate the info, Since my place is so isolated, it is hard to get any one up there
so i wind up doing everything myself The elev. is 7800 ft. I am hoping to covert to propane before i take it up there. I saw where US Carburetor sells a tri-fuel conversion
for about $270.00. If any one knows of a better system, please let me know I will try to send pics. of the unit later today after work

I understand if doing so you need to to keep each leg equal, but that could be difficult
The best connection would be to wire the generator itself for 120V only. That way, you get the full rated power at 120V, and 'balancing' your load is not a concern...

If you will not need 240. Then I would go with 120. More power that way.

You will lose about 1000-1300 watts due to altitude. So you will have between 5200-5500 watts at 7800 ft altitude. You can do a lot with 5000 watts. I used the tables in the Onan T-015 bulletin. You will be between 80-85% of rated output.

really??? more power????

more useful power for a large 120V load and only if balancing issues arise.

and if the engine is de-rated 1000 watts due to altitude
there is an extra power available for out of balance load

ie. gen max 6.5 KW engine max 5.5 KW that could be split 3.25 / 2.25 KW

but yes; with no 240 volt loads,
if it is 120V now .... leave it.

yes provided you connect to the cable with devices rated for AL

also be sure you use the correct gauge

Make sure you use the grease that is used on the connections that keeps the aluminum from oxidizing.

I like Noalox for aluminum.
