My Personal seem to be really confused since 1.25.0 or so. Before that version, they followed a very predictable pattern when under Self-powered or balanced TBC mode. Now I sometime have really odd days that don't make much sense.
Today, for example, once the sun came up over the mountain around 730, my system started charging the Powerwalls while the grid covered the household use (including charging all three Teslas). Around 9 am, it stopped charging the Powerwalls and decided to help cover some of the household load for an hour. Then around 10 it started charging the Powerwalls again. Then it sent everything to the grid for a few minutes. Then back to the Powerwalls...then back to the grid... and then back to the Powerwalls until finally it decided to send everything back to the grid for the rest of the day.
Is anyone else seeing this unpredictable behavior? I understood things better when it would charge the Powerwalls non-stop and then send everything back to the grid for the rest of the day.
