And how much of that goes through the powerwall?
I’m happy to give you chapter and verse if you want, rather than answer one question at a time.
But to answer that one question… on average… 7.5 kWh/day of solar went into the battery, 1.3 kWh/day of grid went into the battery, and 7.7 kWh/day of battery went to the house. A tiny amount went out from battery to grid.
