I believe the way to do it codewise would be to add a subpanel at the base of the solar array, with a breaker in it feeding the dedicated solar circuit (the inverter or inverters -- often I end up with multiple inverters to get to 50A anyway unless using a single 11.4kW, so am adding an inverter combiner panel for that reason) and a breaker feeding the EV charging outlet. It's legal to connect the PV to a subpanel, or a series of subpanels, as long as you follow the 120% rule all the way back through every panel along the way.
