Here in NM the main utility will not allow a zero sell installation, period.
Some heavy hitters have been trying to get it allowed, but so far haven’t been successful.
Hence my asking what the rules are in other places.
Thx Jay

The interesting thing to me is that a ton of industrial equipment has regenerative braking that puts power back "on the grid". Lots of things with a frequency drive and a motor that stops has been built this way for 30 years. Things that stop like CNC machines and elevators. Pretty much anything that stops quickly and doesn't have a big braking resistor on it just pumps the power back to the AC side.
In 20 years of owning and running industrial facilities, no utility has ever once had any concern about that.
FWIW,
