You'd need a lot of panels, and at least enough batteries to charge the car alone for a couple of hours, as buffers. Level one charging would be much easier, and cheaper.
If you get the dual MPPT input version - you could use around 3000 watts of panels (+/- 10 good 300 watt panels). On a sunny day you could then get about 12 kWh of energy to charge your vehicle but only if you charge during the day. You could add more battery storage to the unit to store all that solar energy so that you can level 2 charge after the sun goes down. Of course, many other options, but this would use the full capabilities of such a unit. Personally, I would look into a commercial grid tied solar system with something like the SMA inverter that has a 120 VAC outlet that works in the off-grid mode, although that would limit you to 1900 watts of level 1 (in good sun). With a properly sized system, you could get about the same 12 kWh as there is usually 7-8 hours of usable sun (off grid) - and you will save on your electricity bill 24/7 (on grid).
Bottom line, many many ways to "skin this cat", however, my opinion is that the solar generator is not the answer unless you must have the inverter/battery unit easily transportable for some reason (between fixed solar panel installations
