@aspeake I assume we will need to add error-checking for multiple batteries? I.e., you can't have two EV batteries, and you can't have one EV battery and one home battery. See here for context. Unless you are trying to address this limitation.

Yes, for now we plan to limit to 1 EV/unit. However, the current implementation does allow for one home battery and one EV battery and expects separate schedules for each.

I assume that probably won't work, for the same reason that modeling two home batteries wasn't previously supported. But we can worry about that later. More of a heads up for now.
