Will the 12000XP ever get UL9540 for ESS RSD when paired with approved batteries?
It seems it's only UL9540A.

As far as I’m aware, this is not something currently in development. So, at this time, I would have to say no.
If the 12000XP is wired as pictured do you have to comply with UL9540? Or does it not need to because it isn't actually grid tied and there is no actual point of interconnection?
