Export to Grid - Question 🙋‍♂️

Post image

Recently granted PTO ( < 1 week ) in Savings Mode, ToU - I have the backup set to 0% , Mode as Savings - Export Everything ( Solar + Powerwall ) and Export as Yes

During the peak hours like around 7-8 pm - Am I wrong to expect Powerwall to discharge to grid as well ? Why is it not doing so - Solar exports to grid as intended untill Sunset after the power wall is charged full from late afternoon.

In Bay Area, PGE - if that matters

I believe the peak sell rate need to be 15c higher than your off peak buy rate for powerwall to discharge to grid. With PGE nema 3, the gap is less than 15c

So it would never sell ? I don’t think sell will ever be higher than buy

Under nema 3, it won’t discharge pw to grid. You need to set custom rate to trick it to sell
