Hi Norm,
Yes again I was thinking more about the people who had batteries already and not about people going out
to get a battery to charge their EV at night .Some people need to be off grid as it would cost more to connect power.
There are still other alternatives like charging your EV on the Weekend or use your solar during the day to make power at night.
Using electrolysis to produce hydrogen from solar energy during the day and then using that hydrogen to generate electricity at night is a feasible approach.
Cheers
Max.
