Background. I have 11.6KWH Solar and now 2 powerwalls. have FPL service and now am on TOU.. Current peak during weekdays is 6am to 10 am and then 6pm to 10pm.. I have had solar for about 2 years and was paying 0 to FPL for power ($9 connection charge only). Bought a used 100 D Model X in August 2019 and have seen consumption go up from 40KW per day to about 55Kw (Average)
My Solar production average is about 45Kw
What I am trying to accomplish : Trying to be self sufficient but if i have to take power from the grid, use that ONLY during off peak rates..
What i have tried so far :
Option 1 : Using advanced setting on the Powerwall to setup peak and off peak times
Issue 1: Powerwall will not allow to set 2 peak times, so peak will have to be setup as 6am to 10Pm
Issue 2: Powerwall wont charge from excess solar during peak.. which in my case is the full time solar is producing.
Issue 3: Powerwall will not charge from the grid during off peak
So this option is pretty much useless in my case.. It wont charge from the sun and wont charge from the Grid..
Option 2: Using advanced setting on the Powerwall to setup peak, Shoulder and off peak times
Per documentation, Powerwall will charge during shoulder and also use PW power to support demand. i tried this today, i setup 6am to 6pm shoulder and 6pm to 10pm Peak and 10Pm to 6 am off peak. But with this setup, it still consumed power from the grid at 6 am while the PW was at 100% so dont know what i am doing wrong !!
Option 3: Self consumption mode : this works best until i plug my car in to charge.. i can plug the car only after work so 7Pm or later, when i do that it first pulls power from the PW and only once its down to reserve levels will it pull from the grid. Now come 6 am the next day, i am again paying peak power rates
