3-Potentially mortal: If your EV have a 400V battery, connect directly a 400V output of your EV to a MPPT input of the inverter.
My system is AC coupled (Sunny Island + Sunny Boy)
What I would like to do is connect 400V battery to PV input of another Sunny Boy (or other GT PV inverter), with its frequency-watts range set to curtail 100% before the GT PV inverters that actually have PV panels start do do so.
Ideally this would be done with a bidirectional inverter, so before photovoltaic production is curtailed, the EV battery charging is ramped up.
What I'm currently hopeful for is Sunny Boy Smart Energy (3x PV input + 1x battery input) can do this. It has both PV and battery, so diverts surplus PV (beyond inverter capacity) to battery. What I don't now is how all that is controlled with AC coupling - want battery drain curtailed first, then battery charging ramped up, then PV production curtailed.
