Having the ability to operate our home off the grid is a dream of mine too! Since we've moved away from the city we experience quite a bit more power outages (frequency and duration) and my mind just goes into self-preservation mode during bad weather events like we've seen these past few weeks. In the short term we're relying on a massive power station to run the pellet stove fan and auger for supplemental heat and we can also plug the fridge into this if we needed too. This only gives us around twelve hours though. My goal is to have solar and a powerwall set up eventually but I doubt it'll be in this house I'll probably wait until we downsize into something smaller and more sustainable.
