Only challenge here is $.I have been thinking about this lately and have some thoughts.
How about a house battery backup with enough battery to cover overnight loads plus average daily EV use. Add enough solar to recharge the house battery on an average day. Now you can charge the EV from the house battery over night, charge the house battery from solar during the day, and still have enough battery capacity to cover an overnight outage. In a long power outage the EV can top up the battery if needed.
My EV, for example, has about 100 KWH battery.
I commute about 90 miles per day, round it out to about 30 KWH.
So for a typical day, I'd need a full rack of LifePower 4 to charge the EV overnight, and enough panels to charge that back during a normal day, so call it 8 KW of panels. Not crazy, but you are probably at $10-12K for this solution, above and beyond normal house loads, blah blah blah.
Now that I write this out..........where is my credit card again?
