Same for me, I made a choice back then, and only realized it was a mistake in hindsight, to set up a small storage system, thinking it would just serve as a backup for blackouts. Since those have mostly been very short so far (a few seconds or minutes), I went with 8kWh, while the car has 74... Today I'm expanding it, aiming for 38kWh, which is still much less than the car. Even though the price of LFP batteries has dropped significantly, it hasn't fallen enough, nor has the cost of grid power risen enough, to justify aiming for 100kWh to have substantial autonomy for most of the year, including heating. Using the car as part of the system would be fantastic, and the technology is all there to make it happen, except for the will of manufacturers and the political drive to go in that direction. It's not happening because they don't want people to be self-sufficient; they want large power plants, not semi-autonomous homes and warehouses. But the fact is, economically and technically, the former makes no sense, while the latter does.
