Why is the grid being used?

[MJ_CA_2019]

It’s Saturday evening, my PV production is winding down and my 3 powerwalls are at 100%. I’m on PG&E TOU-B which is all off peak weekends. I have produced more than consumed every day this month.

I’m using Balanced with 15% reserve.
I know it’s a small amount of grid draw but it’s annoying…

Why Tesla? Why?

Do you have storm watch on? Were there any high wind warnings for your area? That would keep the PW from discharging as they on standby incase the power goes out.

I have the setting on but to my knowledge it has never activated for me. We are close but not in any PSPS areas.
Notice how grid was used for a small time in the morning also? What gives??
