That's pretty neat. Reminds me of what people have done with direct ties to Prius packs (PriUPS).
Can you share any specific mini split models that you have seen, or heard of, being used this way? Which Tesla pack? Was this with a 350v DC (14 module) or 400v DC Tesla pack (16 module) legacy Model S/X pack or some other Tesla pack? My napkin math says the 350v DC packs have a better chance at compatibility. Was the pack still in a car? If so, did you run into any problems with the car software making things harder than necessary?
