That's about 10 months of power for my home and car (gas heating). A 40' container on my drive or buried in the garden would power the house through the winter. It's crazy when you think how solvable season-shifting domestic power use is once you exclude the $1.5m price tag.
It's also crazy to think about how energy efficient it is to shorten supply chains where possible.
It'd be better to build more insulated and air tight homes (bonus if they're not single family - shared walls save on heating). Then it doesn't require so much energy to heat and cool.
A lot of things are solvable if you don't care how much they cost
What about battery self-discharge over months?
