Backup Generator,
A little camp size
1800.
It won’t run the
Well Pump.
I lose power,
I also lose Water.
Been there, done that. You need a 5000 watt to run well pump, fridge and deep freeze. maybe some lights. Have an electrician connect it to the breaker box with an interlock (to prevent backfeeding the line). Plus it enhances your home value if you decide to sell and get out.
Sounds like you need a storage tank. We have a 3600 gallon storage tank, and if we are careful with water we can make it last a month. Even a thousand gallon tank can be made to last a week. Ours is on a tower gravity feed but it doesn’t need to be. And a small 10-15 gallon per minute pump will still give a decent shower.
