With a charger that goes down to 750w you can charge your ev off grid with an inverter.

I currently do it with 12 100w panels. I run ac/dc converters to supplement additional dc from the grid to charge at 1500w, but have a 750w charger for emergencies that will charge directly from the sun with no grid. It does require a small buffer battery to work reliably.

at 750W, even with perfectly efficient energy transfer, you're looking at adding ~2.75 miles of range to your car every hour it's charging. That means during winter, if it's sunny, you might be able to charge your car all day and get 25 miles from it.

You'd be a lot better off with a jerry can and a $500 gasoline generator....

750W is a lower bound.
