Time-Based Control (also referred to as load shifting) helps you maximize savings through smart charging and discharging of your Powerwall. If your electricity prices vary during the day, you are likely on a time-of-use plan, and Time-Based Control would present the best economic value for your system. Time-of-use plans are utility rate structures where electricity prices may vary depending on the time of day, the day itself or the season.
Utilities usually break time-of-use plans into three periods:
- Peak: High energy demand hours with most expensive prices
- Off-Peak: Low energy demand hours with least expensive prices
- Partial Peak or Shoulder: All other times
How to Set Up Time-Based Control
Before setting up Time-Based Control mode, obtain your specific time-of-use plan, which is typically found on your electric utility website. Once you have set your preferred rate plan, you can always change it through the following steps:
Step 1: From the home screen, open the ‘Settings’ menu.
Step 2: Open the 'Powerwall' menu.
Step 3: Under ‘Operational Mode,’ select ‘Time-Based Control.’
Step 4: Set your preferred rate plan by tapping the ‘Utility Rate Plan' card.
Step 5: Set your preferred Backup Reserve by adjusting the slider at the top of the screen.
