Here’s where they would flip a switch and shut down your EV ,sorry
Not mine. In the past 365 days I bought from the grid less than 42% of all the power we consumed at our house. My solar system provided the other 58%. And we're in the middle of upgrading it and getting an EV.
If my calculations are as accurate as they were with the original phase of the system a year ago, my system will produce 85% to 95% of all the power we consume, including charging an EV to drive ~200 miles per week.
LOL! A cruel irony if there ever was one...
