Hi,
Can you recommend a system that can charge a Tesla offgrid from solar. 2-3kw. Minimum is 5A/220V in the car. So just an ordinary 220V wall socket.
I park the car by my cabin over the weekend (48 hours) and would like to slow charge the car during sunlight. What minimum system would you recommend?
3kw inverter, battery and 3kw solar? I don’t want to spend to much since it’s just a hobby project.
How can the car detect ground from an off grid system?

Yes, why not...use the standard "brick" to charge the car.
I'd recommend to place a good/professional smart switch in between, like the Shelly Pro 1PM
With a Multiplus-II GX you can use Node-Red to define your own charging algorithm, using Node-Red, use the Shelly to switch charging (the brick) on/off. or via Tesla remote command based on Home Battery and Car SoC, for example.
If you want a smart charger instead, there are some DIY projects, using a Simple EVSE as the core device.
