I have entertained the idea of designing one in the 2- to 3-kW range, but have learned that the CHAdeMO connector costs on the order of $2500!! That makes the value proposition much harder to swallow.
Appreciate all the references - they sometimes get "buried" in topics that seem off-topic to off-grid/SolarElectric./EV stuff. It seems as though this "home" energy supply topic has moved on.
Motor Werks makes a clone CHAdeMO for $900 or so:

They also make CHAdeMO based EV chargers that can operate up to 800 VCD -input-, but don't believe they make a 240 VAC split phase inverter - nor an MPPT based charger for direct PV use.
Obviously, you have substantial "solar" experience and a serious DIYer. I do have substantial experience with UPSs - mainly APC/Schneider - and they work well for the Prius/UPS "generator" (directly tied traction battery - which I actually have two of!). The largest of the SURT line (double conversion, highest quality) do accept the 400 VDC needed to work with the Leaf. HOWEVER, they also center tap the DC voltages to use the standard battery cages of the smaller SURT units. I think this precludes the use, but I'm not sure. I'd like to run it by a serious electronics designer type that can review the wiring schemas to confirm or not. I have all the information to do so. Can you help? or know someone?
