V2H can charge home battery systems, but V2L "cannot". There's obviously a market for "plug the 240V outlet on my EV into my house battery. Use the car to charge the house battery while the house is running off the house battery".

Someone will make it work.

I have a 2027 Bolt, and it has V2H but not V2L, and I just want V2L to charge my home battery system like you said. Haven't figured out a way yet. GM put encryption in that NACS port.
