Mac, You can charge with DC directly from a PV solar array without an inverter or regulator. The current is self limiting by the amount of PV solar power you are making at any moment.
The magic is knowing know how to trigger the charge port communications so your EV controller knows that there is a safe connection to a DC power source. Perhaps the will get you started: https://www.evcreate.nl/chademo-fast-charging-in-diy/ Be safe when working with 500Vdc.

Even if we reduced the charge rate it would still be a heck of a draw - the chargers in the EVs are greedy. I'll be curious to hear if anyone has a solution, but my bet is that you need to give the EV a deep well to pull from (probably deeper than a battery bank or PV array can directly and consistently satisfy). -Matt On Mon, Apr 12, 2021 at 7:55 PM Mac Lewis <[email protected] <mailto:[email protected]>> wrote: Sorry, I should have clarified, I am interested in EV charging with no grid available.
