I am a new Powerwall owner in Northern California. I have a 10.36 KW solar panel system from SunPower and two Tesla Powerwalls.
The EV2-A rate plan from PG&E has peak rates from 4pm-9pm and part-peak rates from 3pm-4pm & 9pm-12am. During the winter period (October - May) there is only 1.7 cents difference between the two rates (35.2 cents vs. 33.5 cents).
I am wondering if I should combine the two periods as one peak period from 3pm - 12am in the Tesla app to ensure my batteries discharge as much as possible during that time, instead of stopping to discharge at 9pm (which it did today even though batteries were still close to 60% charged). I keep the reserve at 20% and on a somewhat sunny day like today it charged to over 90% before 3pm.
