I understand the concern. We have generators for when the electricity goes off, but our problem is the freezer itself.
Everynow and then it goes on the fritz, and the food often is thawed too much to refreeze before we discover it. Then we can whatever can be canned. Clean it out and start over.
It’s a relatively new freezer, and every time they check it out, they say it’s ok. I just think its got a computer glitch or temperature sensor that goes wacky or something.
Last time it happened, I just unplugged it, and decided to forget about it. We have a side by side upstairs, and a regular refrigerator down stairs with a top freezer. I just use those, and dehydrate or can more stuff.
Yes, you have to go with the flow. They aren’t making appliances to last these days. My Mom bought our current freezer as a gift for me in 1982. Maybe I have just jinxed it. Ohno.
Look into wiring a alarm for when your Freezer goes out. It’s generally a red light that goes off when the freezer fails
