Interesting approach to V2G.

Saw this ☝️

 

Seems to take the vehicle DC output from the fast charge port and use a dc-dc converter to step the voltage down a bit (depending on your battery architecture). Then connect it to the mppt panel inputs on a solar inverter moving a string of solar panels.

 

I can see this as being quite clever - especially if the inverter has spare solar inputs.  You could have your panels on 1 and 2 and your car on 3.

 

If the box can talk to your inverter to get the house demand it could then set it's "solar panel string" to provide the appropriate output either to just match the homemload or provide enough for export.
