Huh, I hadn’t seen ConnectDER before. That’s cute. It’s not entirely clear to me how it interacts with power sources in the house, and it’s also not clear to me whether it’s standardized enough so that a different MID could be used in its place with the same inverters/batteries/whatever. I would love to see the industry standardize on a MID protocol well enough for applications like V2H/V2G to work without absurd levels of vendor lock-in.

I suppose another potential issue would be exceeding the capacity of a panel bus. Balcony solar has the same problem, and I guess no one os likely to connect enough balcony solar units to cause a real problem.
