It can handle 3 phase.
I'm still not sure about max DC charging though. Might be ~ 16 kW (38 Amps at 400 volts)
If the PV inverter and smart hub work as expected then this is an extremely modest cost box for a home that wants those functions.
Pretty sure it's only single phase. They use the term "split-phase +120/-120" but I believe that's just talking about N. America's 240v, two legs of 120v and 240v between them compared to Europe where they have one single leg ~230v. I agree though, looks to require a continuous 64a circuit(80a breaker) which as you said would give a maximum of 38a @ 400v or ~16kw. Looks like the J1772's are capped at 38a or 9.2kw, not sure how that gets divided up if using 2 J1772's at the same time, I mean 32a and 32a would be fine for a 64a continuous circuit but not 38a and 32a.....
It would have been nice if it had accepted 277v(one leg of a 480v commercial circuit) but I suppose that would have required step down transformers as 277v is too high for the J1772 connectors, although I believe Tesla used?(or maybe still does?) accept 277v for it's EVSEs but maybe that's more a car charger thing than EVSE thing.....
I agree though, this EVSE/charger looks like a cool thing, especially for a large dual EVSE home or a small business. I'd think you'd want at least a 200a panel to feed this monster!
