I’m not convinced a diesel generator will be a good idea in 0 degrees temperature. If anything I’d say backup propane. JM2C

Diesels are fine down to about minus 18 (though a bit sluggish to start at the lower temps), and, due to the efficiency, the same size tank will run your diesel generator for twice as long. A propane backup is fine, but you are better off keeping the propane for cooking.
Second the solar chargers for small stuff though - they are efficient enough that we use them already for our cell phones, outbuilding lights (the ones rarely used) and our walkie talkies.

Well, if the generator's empty and the diesel's kept warm it should be alright, and there's additive to de-gel diesel.

But I definitely see your point. I haven't gotten one yet, so maybe I'll go for propane instead. Thanks for potentially saving me some $$ and headaches.
