Configuring your Powerwall to maximize savings on the Solar Billing Plan
Follow these steps in your Tesla app to maximize savings on the Solar Billing Plan (under the new Net Billing Tariff, a.k.a. NEM 3.0)
Step 1:
From the home screen open the ‘Settings’ menu.
Step 2:
Select ‘Powerwall’ at the top of the screen.
Step 3:
You can adjust your backup reserve at the top of the screen. 20% is generally recommended, however during the month of September you may want to lower your reserve more than usual to optimize savings. For Operational Mode, select ‘Time-Based Control’.
Step 4:
Click on ‘Utility Rate Plan’ under ‘Time Based Control’. Select your ‘State’ and select your ‘Utility’.
Step 5:
Select your ‘Rate Plan’. For PG&E, select 'E-ELEC-NEM3'. For SCE, select 'SCE-TOU-D-PRIME-NEM3'. For SDG&E, select 'SDGE-EV-TOU-5-NEM3'.
Step 6:
After selecting your rate plan, tap ‘Done’.
Step 7:
To enable Powerwall to take advantage of times when the utility gives high value for kWhs sent to the grid (mostly 6-8pm in August and September), scroll below ‘Time Based Control’ to ‘Energy Export’ and toggle to ‘Everything.’
Step 8:
If you have Powerwall 3 or Powerwall+, be sure that "Permission to Export" under "Advanced Options" is set to "Yes."
