Roger on the CHAdeMO, islanding, grid isolation and 240V PV microinverters and how this "box" would have to serve as a gateway for the proposed functionality.
The 10kW PV capacity on the CT was assuming that the onboard inverter would be bi-directional. But thinking about it more would mean that it would be a DC-DC converter not AC-DC inverter. So a separate circuit.
Also I'm still surprised over your energy consumption and that driving is a small proportion of your consumption. I'd seriously be investing on energy reduction rather than production. Obviously building new, like I have, recently, allows for more control of consumption, especially thermal loads. But it can and should be done I think, less is more. When our heat pump is on it heats the whole house with 400W with us inside at 23C and outside at 5C, (with the wind howling at 50kmh avg) but that's mainly because we have 150mm SIPS panels for insulation, and double glazed windows etc.
BTW did I mention our current house (we're starting the next one next year) is actually the same shape as a CT, facing the prevailing wind direction, with the PV on the vault side roof etc which is attached to the 300m² CT garage/workshop of the same design. Once the other one is built this will become the guest house.
Anyways, looks like this is product is about as close as it gets for the proposed gateway box and to use PV directly. Does 50kW and has a PV input option where it suggests the PV nominal power should be at least 2x the max output power. Minimum PV size would be around 14 panels or so (350-600V).
Rather large box I suppose, not sure what the cost is either, or what is actually in the box.
