We are going to invest in a stand by generator this summer-I think. The problem will be fuel. We are all electric and I'm not sure what's available-likely have to set up a propane tank. In a long term power outage, I'd also like the option to be able to turn it off to conserve fuel.
Like maybe turn it on once a week to power the well pump and fill up the barrels and take a shower. Then shut it off.
I'd like to have a generator that would work on propane, solar and wind. Not sure they make it. LOL
I believe that "Harbor Freight" offers a convertible pigtail ,
so that you can switch between natural gas and propane for a generator.
There may also be a conversion kit for gasoline conversion to diesel
(which is actually, #2 home heating oil taxed for DOT road use).
Long term storage of gas or diesel requires "Stabil' (fuel stabilizer).
