My option is to charge up lots of old car batteries and use them as point-of-use power sources with inverters where necessary. I can run the gas central heating from them for instance (hot water at least) I can run the router and charge up all our devices.
Not going to attempt the freezer I think.
Practice your changeover and get the bugs worked out.
Yup. I have a bunch of 100aH deep cycle batteries for solar kits. Got them wired as 24v to lower the amperage, and a big inverter tied into my electric box. I'd be able to flip a few switches and be good to go.
a 100aH battery if it's in perfect condition theoretically holds 1.2 kwH if you drain it at the rate they rate it at which is probably 20A. Expect quite a lot less in practice especially in cold weather.
Got batteries?

Just right!
Turn off everything you don't absolutely need.
