So I am staring at my $164 electric bill and doing some quick math. Electric is pretty cheap in Oregon .055 per. So I used 2666 kwh in the last 28 days. My average daily usage was around 50 kwh in June and over 110 in December. December was abnormally cold as November I was down around 55.

Going by these numbers what is the best way to size a generator so I can rob enough heat from it to flatten out some of the demand in the winter, yet not run at almost no load in the summer?

My house is fully electric and I also have a wirefeed welder and hot tub (outdoor). My wife likes it cold and we run the AC pretty hard in August.

I plan on burning WVO and operate as much off grid as I possibly can.

One thing I have thought of is oversizing the generator and running say 16 hours on it and charging a battery bank then turning it off at night. Issues I see are having a load of batteries around and having to start and stop on diesel.

I thought I wanted a 16/2 with a 10K but this seems like it might be a bit large for my needs.

Thanks
