Outside June - September, my rates are pretty much the same so I haven't really messed with TOU settings, but now that it's June I was playing around with them and not seeing results I expected.
peak 11a-6p M-F
semi peak 6a-11a, 6p-10p M-F
off peak 10p-6a
Peak and semi peak are basically the same rate (fraction of a penny difference) so let's just say 6a-10p is expensive and 10a-6a is half the cost.
I set 6a-10p as peak and set TOU as cost. I figured it would charge the PW on the weekends, then use PW at 6a until solar generated enough, then send excess solar to the grid, then go to grid power at 10p. In this scenario, the PW would maybe be used an hour in the AM and bout 7-10p. I figured the PW's had enough weekend power to cover that, but couldn't get that behavior. I saw TOU discharging PW during peak and sending all solar to grid. No, don't want that.
I switched to balanced. I figured this would do what I wanted. Nope, still discharged PW during the day and send solar to grid.
I used this guide (Powerwall Modes of Operation with Solar | Tesla Support Australia) and tried various settings (only setting off peak, leaving the rest as shoulder, etc.) but I couldn't get the behavior desired. The doc is for Australia, so maybe that's another issue.
Any TOU experts here have any suggestions for settings?
I'm hoping to charge the PW's fully on Sunday. I can run grid sundown to 6a Monday (off-peak), then use PW/solar until 10p weekdays. I do have automation via HomeAssistant that can switch modes on time based, so switching the PW to backup at 10p to force grid use and TOU at 6a is an available option. I just can't figure out how to get solar to power the house, then send excess to grid M-F. The PW's always start discharging during the day and all solar goes to grid.
Only thing I can think of it I have to let it do it's thing in TOU mode to learn for say a week.
thanks!
