[AT] Generator LP fuel consumption

[Dick Day]

Cecil,

I have a Generac 7.5KW gas unit that has maybe 1 hour on since we bought it 
4 years ago.  Prior to us buying it, it seemed like we were in the dark at 
least several times each year. Now that we own one.... :)

I have a fascination of generators, not sure why.  I've looked at the 
pto-driven units that both Northern and Harbor Freight carry.  If Generacs 
really are junk, should we consider moving to one of the pto units?  Last 
year, we dodged the black-out bullet by half a mile. People that close to us 
were without power for up to 3 weeks.  Our lights flickered and that was 
all.

One of these times we will need the generator and now I'm concerned that 
maybe buying the Generac was a mistake.

Suggestions?  Comments on what's wrong with that brand?

Thanks for the info.

Dick

Fully loaded it will burn 60 gallons per 24 hour day on gasoline.  On
propane, add about 20%.  half load would be about 55% of full.   If you
need this much power, ok.  However, I have sized generators for many
different uses, and if you can get by with the smallest unit possible,
the cost savings on fuel will outweigh the original cost.  Diesel is
half the cost of gasoline on the same loading.

Most of those Generacs were junk and meant to sell to homeowners with
nat gas available.  They had a bad habit of blowing the shutdown circuit
board when they detected a power surge in the power company line.  It
would then start but not run.
