One thing I haven't seen much coverage on is how to tap into the giant batteries we're driving around in our electric vehicles. These are much bigger than what's currently being deployed in houses.

The V2H standards are just now coming online: https://electrek.co/2025/02/21/nema-bidirectional-ev-chargin...

Arbitrary vehicle to home/home battery/grid connection is indeed coming in very short order.

There are other products already available to do it (DCBel), and it can be hacked of course, but at the current moment everything comes with substantial corner case blind spots, mostly related to grid-forming/following switching and to the resilience of the power electronics.
