I was tempted to buy a Honda 2000W electronic generator at the state
fair last year because they were on special for $899. (that's a great
price) I decided not to get one because (1) I hate spending $900+ and
(2) the electric power here is very reliable.
But I'm still interested in emergency generators even if I may never get
Does anyone have experience with 2kw to 5kw diesel generators? Yanmar
makes them -- very expensive and hard to find -- and there are Chinese
knockoffs for less than $1000. (If you search on "Yanmar diesel
generator" you will probably find more links for the Chinese generators
that just have the word "Yanmar" in the page somewhere.)
They run at 3600 RPM rather than the 1800 I expected. So is there any
real advantage over gasoline? How long do 3600 RPM diesel engines last?
Gasoline engines are sometimes only rated for a few hundred hours. The
online specs never give this rating. I guess it's safer to store 100
gallons of diesel fuel during the blizzard (or hurricane, or whatever)
season than it is 150 gallons of gasoline.
at alt.energyhomepower are alot of off grid users. for occasional use
a Tri power honda inverter EU would be my choise. Its rpm is load
dependant and 15000 hrs life is known, vs 2-3000 for 3600 rpm. With
Honda you pay but its worth it, Look at Yamaha, There is alot of cheap
chinese stuff but quality is not well known.
And what are you going to do with 100 gals of diesel when you don't
use it? That's one of the problems with either gas or diesel, ie
having a sufficient supply of fuel when you need it and rotating it so
doesn't turn bad from sitting around. With a diesel, if you have a
heating system that used fuel oil, I guess you could tap into that to
run the generator. However, if you have natural gas available, IMO,
that is the best fuel.
I've got an EU2000 and it is a wonderful unit. No, it's not cheap, but
it's quiet, reliable and light weight. It will also run about 12 hours
under light load on it's internal 1 gal tank and there are adapters
available that let you feed it from an external tank. You can also
parallel two of them.
I don't know if you have a tractor, but I bought a PTO driven
generator for mine a year or so ago. That solves the fuel storage
problem. I mounted it on a small trailer and park it in the shed. When
I need it I hook it to the tractor, drive up to the house and plug it
in to a transfer switch. I bought a 12kW generator on ebay for $600.
If I have projects far from the hose I can pull the generator out
there and run my power tools.
