+1 fo sho :)
I just restored a 50yr old 12Kw air-cooled Onan. A little TLC and new
regulator an viola got Forrest's Standby controller and
for around $600 buck we got a nice genny to run a medium site. Its crazy
how a single diode and a few dried caps caused this
thing to be unrepairable. Motor and generator was in great shape.. it
just wouldnt produce voltage. It has a simple regulator board
that provides the exciter a voltage which is then regulated for a
consistent output.

I always pick NG first, then propane. But I do it to save money and
increase reliability. Gen sets are really difficult to maintain in
that they are easy to forget about. Both NG and propane burn cleaner
and cause less troubles.

I don't think it's fair to directly compare diesel fuel to natural
gas, because one is portable in just about any container (in a
real emergency), the other is not.

I am assuming a BTU of fuel will make so many Wh of energy.
If perfectly efficient 1M BTU =292.3 kWh
That would cost me *$35* from the power utility.
A gallon of diesel is abou $3.25 around here. 139000 btu.
Diesel then is about $23 per 1M btu.
However diesel engines are only 30% efficient so it will cost
me *$76* in fuel to make that 292.3 kWh
If that assumption is approximately correct:
I pay about $7.80 per decatherm in the winter for NG. A
decatherm is 1 million btu
About half that in summer.
$7.80/.3= *$26*/293.3 kWh for NG not considering depreciation
and maint of the generator.
It seems to me that NG is the hands down fuel cost winner?
Anyone see mistakes in this?
