Hi all,
Would it be possible to hook a small solar panel system to an EV and use the EV
as the battery storage for an off grid solar system? What would be needed to
make that happen? I envision solar panels connected to microinverters which
would then charge the EV. Then if you needed power at night, you could use
some power from the EV. Would that work? Would you need another part to that
puzzle to get it to work? Would it cause problems for the EV?
I am not looking to do this myself but we had a guy come and charge his Tesla
at our place. He has a lot and camper where he goes camping and would like to
install solar and be off grid. I was just wondering what that setup would look
like.
There are a number of possibilities. AFAIK, none very workable right now.
Nissan supports home power (grid spoofing) for the Leaf but, AFAIK, only
in Japan.
Tesla offers the PowerWall which is very good though it uses only it's
own battery; that is, it will not use a car battery for backup storage.
It will operate off grid so you can charge a car from it and PV.
With a conversion, it is pretty straight forward to use the battery for
home backup. But, factory EVs have intentional stumbling blocks built in.
I'll Bcc: this to a local Tesla group member that hopes to develop a
scheme for charging his car from PV off grid. Even though he has a grid
connection. Perhaps he will contact you.
