Absolutely agree; propane is the way to go if you can. You could also get a gasoline generator and add a bi- or tri-fuel kit to allow you to use propane but still keep the gasoline capability.
The second thing is that it takes 4KW to start a refrigerator, 1KW will not do.
Incorrect. 4000W/120V = 33.3 Amps. I guarantee your household fridge does NOT draw 33 amps when the compressor kicks on. Also, I have a fridge that is about two years old and I was able to run it, a single lamp, the power vent for my hot water heater, and my internet connection with a small 1KW generator during our Halloween week power-outage.
Cool, glad you have an efficient fridge. I have seen a vanilla fridge stall a 1KW generator, flat not work and fail ugly. For the money, I’d do 4KW and not worry.
Agreed. A large fridge will draw 2-2.4 kw starting though.
We live out in the country and have a propane tank for our heating and cooking. Would it make sense to go to our propane supplier for an electrical generator that can run off the main tank when the grid goes down?
