I didn’t realize this was covered before. But for context, my primary need is just as battery backup for a few days if power goes out. That wouldn’t degrade batteries because it would be rarely used. For context, our utilities company PG&E sent a letter telling customers to expect outages during fire season. One of the options they suggessted was a generator. They service 5M customers, but there must be many other customers who have occasional outages. If it isn’t overly expensive, an option to provide V2H (not necessarily V2G) would be very attractive.
