Very promising really like this. I wonder how this works when the solar inverters are the micro versions that are installed under each panel.Here is a new option for bi-directional charging that is very similar to VW's system, but its available now for pre-order at $6649, does both DCFC or L2 charge, has 15kw inverter, 20kw of solar input MPPT, and replaces your solar inverter, does emergency backup with and without a home battery, and can charge 2 cars:
DCbel charger, inverter, backup power
It will be interesting to see what the price is on VW's unit, since this one is so similar. One thing I don't like is they charge $7 a month for their app. It does DCFC charge at 3x faster than L2, getting 60mi/h of range. Unlike the VW unit, this one has all the specs and pricing available right now, and it looks good but expensive (and I expect the VW 22kw unit to be expensive.) It looks to me there will be many options like this coming up in the next year.
Edit: added my name to the reserve list for funnsies
