Thanks for the answers. I used to work for a EV smart charging company (Kaluza) that ran a V2G trial. V2G was financial success for the users, but I always thought the wall box was a potential blocker. I don't think the 2kW output is a big issue as the customer could still reduce there load when required, but the elimination of a wall box makes onboarding much easier.

As long as the inverter can also provide charging this definitely has some potential.
