We live in the middle of nowhere in rural Wales, so yes...
We always have several charged torches, lamps, etc., and several reasonably meaty powerbanks so we can keep mobile devices charged. My phone (Xiaomi Redmi Note 9 pro) lasts at least 3 days on a charge. Mind you, round here the phone signal is a bit sketchy, and I'm unconvinced as to our fibre only landline working with no mains. It does have a battery backup in the modem box, but its BT, so I don't trust it to work.
We have a logpile, and a wood burning stove, but we generally have oil fired central heating, which of course needs mains elec to work. The house does have a generator input socket, but we don't as yet have a generator. I'm hopeful that with the aid of a generator, the solar PV could be persuaded that we had mains, so could play its part in supplying electricity, but of course on dismal days it may only do a few hundred watts.
We always keep a healthy supply of food in the house, because the nearest shops are 12 miles away and they're crap, so effectively its 25 miles or so. I did notice that our supply of Tunnocks caramel wafers was critically low, as we only have about 20 packs left. We have gas fired camping stoves, and an effing great propane cylinder which will run one of them for a long time.
Kim's mention of an inverter does remind me that I've got one, and we have two ickle cars, so I wonder if they could be persuaded to fool the PV system that we have mains, via the input socket, or at least be able to charge a laptop or run the desktop PC.
