If I try to charge my Model 3 at night from the grid, will I drain the Powerwall? Is there a setting that let's you stop the battery from discharging? I'm planning to have a new 6.6 KW system installed with 2 Powerwalls, and I'd like to know my options.
Also, if I want to charge the car during daylight hours, will a 6.6 KW system be enough, or will I end up using a lot of grid power? Thanks!
