> 3 day reserve battery for the house ... All my heating and cooling would be electrical I don't think you've run the numbers here, at all. Battery storage that can provide off-grid heat-pump heating for a single dead-of-winter design night is bordering on impractical. Creating a buffer that could last 3 whole days (4-5x the size) would be blatantly prohibitive. Batteries only make sense for daily cycling to deal wit…
I have run the numbers and with proper insulation and lower sq footage it is completely practical. That recommendation is for people with the money to do it, which is most of us here. I was replying to someone talking about most “rural” people and extended the reply to be relevant to people here. Given I sleep most nights in a hammock in woods backpacking and travel around nonstop, and have no trouble in sub-zero wil…
Okay, I do agree this qualifies as opting out of the housing market.

Sure. I'm there myself on a few topics, and have lived them for quite some time. But you need to understand that this puts you at odds with 99% of society, and as such your example isn't going to be found as actionable advice by the sheer majority of people - even people who agree with you 90% of the way.
Would you mind sharing your numbers? If I just spitball with a 10kBTU/hr design load, a heat pump COP of 3, and assume that your heating requirements are entirely taken care of by that design load for 8 hours at night, that's still like 3 Powerwalls to last 3 nights. I'd say there are better ways to spend those resources, especially considering that batteries wear out like everything else.
