HI,I am new to this forum and this is what i am working on.
I would like to run my present home completely off of the grid and my last PUD BILL SHOWED THAT I USED 3000KWH for 33 days what size generator will i need to do this,thank you
I'm not saying you should not do what you suggest--go totally off grid.
However, there are some gotchas:
Electricity you make with a good diesel genset will cost you double or triple what your utility charges you. Stated differently, if you pay $300 a month now, just plan on 600 to $1,000 a month to feed and pay for a diesel generator.
It strikes me that your electricity usage is much higher than average.
In my worst month, I use 6-700 kwHrs.
Tell me about what you run on electricity. Central AC? Heat pump heat? Submersible well pump? Electric baseboard heat? All electric appliances like water heater, dryer and stove?
How many lights are on in your house at one time? What kind of light bulbs? Big motors? Electric machinery to make a living in a wood or metal shop?
Your total kilowatt-hours per month will not tell us what size generator you need. We need to know the maximum load (in watts or amps) that you use simultaneously to determine generator size.
Once I know what kinds of things you run on electricity, we could make some estimates on what kind of generator you need.
It is generally true that every dollar you spend on conserving electricity, will save you 2-5 dollars in generating capacity. For example, switching most or all lighting to LED, and applying the 1 person = 1 light rule. Heating with propane or natural gas rather than anything electric.
My last bill said I used 200 kWh last month. Just sayin'.
So... Start by reducing your demand, then figure out what else you can do with that diesel. Figure out when you can turn it off, rather than letting it idle all day and all night. It's fine if most things have intermittent power. Just be sure the fridge and freezer have good seals.
And then run the diesel exhaust through a liquid heat exchanger and heat a big tank of water with it. Use that in the winter to heat your house.
