Default Generator Questions?

SWMBO has decreed that we need a backup generator in case of ??? Who am I to argue I'm trying to connive my way into an engine drive welder that will double as a generator. But, if that doesn't fly I'm leaning towards a propane rig due to no worries about stale fuel. First ? At roughly 8000Ft. altitude how much loss/derating should I figure in when looking at specs? Number2 question since our most likely power outage scenario would involve winter winds. How much does low temps affect a propane genset? Number 3 does anyone build an 1800RPM propane genset? Thanks

Just notes.

The run of the mill Generators have to run at a preset RPM to keep proper frequency.

Guessing ???
I would think Some inverter generators may output proper frequency at most any RPM. thus a fuel saving.

Other thing you have to consider is how many gal/hr the generator burns.
fuel storage tank size for days of operation.

For day and sunlight think solar generator.

No one builds a 1,800 home stand by generator that I know of. Even Onan who dang near only builds 1,800 rpm gensets builds 3,600 home stand by units. I wouldn’t sweat it much, if the enclosure is properly designed you won’t hear it.

Chumly has a standby unit about like what your looking at.

What ever you get excersise it regularly and arm it with mouse poison.

I asked about 1800 RPM gens cause I know they would last longer in long term use. I'm not even sure what triggered the Old lady on this. But, I'm not opposed to the idea at all. If I had my druthers I'd be putting together a Listeroid genset like Gerry has. A prepper mentality is not a bad thing in my mind. Oh, SD I wasn't worried about noise I'm better than 1/2 deaf we could run a 6-71 genset with a straight pipe and it wouldn't bother me.

Look at the MEP 002 and 003 military diesel generators. Built to the gold standard with your tax dollars. 1800 rpm . Multiple voltages including three phase. I found one on Craigslist with seven hours on the meter.

1800 rpm gensets
You did not say anything about KW, but 5-6 should be plenty.

Not 1800 but cheap

Check into Generac also. I thought I heard they are offering a 10 yr warranty at the moment. That is one of the popular brands around here.
