I have a Tesla solar with powerwall 3 setup. Powerwall is in self powered mode with charge from grid disabled.
During the day when solar is producing, it preferentially powers the house with any excess power going to charge the Powerwall . Nothing is imported from the grid unless production drops below the house load. If solar is producing a lot (more than house and battery want) it exports excess. So far so good.
When I add charge on solar to the mix, the distribution is as follows (see attached screenshot)
What would make more sense is that the excess solar power after powering the house is somehow split between car charging and battery charging. The grid should only kick in if the house load exceeds solar production.
Thoughts?

- Solar production all goes to Powerwall charging.
- Car charging goes to solar production-house load
- Grid starts importing equivalent to solar production
