I'm aware this is an old thread, I came here because I want to attempt doing something non-standard — if I feed the US UMCv2 220V via some sort of adapter (assume high quality Shucko to US plug) that is not a 14-50 (so, not 240V but 220V, as you'd plug into a European outlet, not a split-phase US 14-X outlet), will the UMCv2 work, and work at 220V?
Long story short, I'm doing some off-grid PV/battery stuff and want a quick and cheap way to charge the Teslas, I'm currently at under 2.5kW of solar, so spec'ing a WC for this project would be costly and overkill. My logic is, get a European-spec inverter that outputs 220V and just plug one of my spare UMCs into it — at 220V+, even a measly 16A would get me over my solar generation capacity (~10A would do it, actually). Now, I wonder if the EU standard is actually 230-240V, like here in the US it's actually 120V instead of 110V (some places 115V), and would the UMCv2 accept that? Does it make any difference internally, like does the UMCv2 keep some sort of state "I'm in L1 mode now, vs in L2 mode" when on wall plug vs split-phase via a 14-50? In other words, does it make a difference internally if it's getting 230V from a Shucko-adapted-to-US-plug vs a 14-50?
Europe is a wonderful place for an EV, and i see more teslas here in Paris than i ever did back home. but a US spec car is just not doable.
Again, I realize this is a super old thread, but I read thru it first and wanted to comment on the emphasized (by me) part above — I didn't really read anything from that experience that would point in the direction of it
not being doable, maybe just some niceties like Nav not being there; for me this would not be a deal breaker if it made financial sense otherwise (and esp if I planned to return with the car to the states at some point). I'm wondering how much better the experience is these days, in particular on the charging front, with the prevalence of CCS-to-NACS adapters and many other improvements over the years. And I guess my actual project above applies too, if it works, plugging into a EU outlet that can deliver 220-240V at upwards of 16A would be nothing to sneeze at — given that the UMCv2 is capped @ 32A, that would be 50% of the speed w/o needing to do anything special at all. I'm wondering if this is the standard experience in Europe, this would make L1 charging so much more useful than the slow-as-&#^$ speed in the US (I know because I sometimes "trickle charge" at rentals in the US).
