I have 2 PW2's and a 8.1kw array. I'm was on time based control and discovered around 4 p.m. these days, the PW are max'd out at 9.9kWh delivery. However the delivery is to the GRID not the home. I checked my smart meter and at the time, it was showing 10.5 kWh being exported to the grid.
My expectation was that during peak cost periods, the powerwall would deliver to the home. This behavior has gone on for the last few weeks I've noticed.
I switched the app to just self powered and the battery export to the grid stopped.
I don't understand what is up and was hoping one of you experienced power wall folks would be able to clue me in?
