Step 4: Set your preferred rate plan by tapping the ‘ Utility Rate Plan' card. Step 3: Under ‘Operational Mode,’ select ‘Time-Based Control.’
How to Set Up Time-Based Controlīefore 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: Learn more about energy data and impact cards in the Tesla app.
Partial Peak or Shoulder: All other times.Off-Peak: Low energy demand hours with least expensive prices.Peak: High energy demand hours with most expensive prices.Utilities usually break time-of-use plans into three periods: 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. 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-Based Control (also referred to as load shifting) helps you maximize savings through smart charging and discharging of your Powerwall. Step 4: Set your preferred Backup Reserve by adjusting the slider at the top of the screen. Step 3: Under ‘Operational Mode,’ select ‘Self-Powered.' Step 1: From the home screen, open the ‘Settings’ menu. This is the most effective way to reduce your carbon footprint and gain energy independence. Learn more about energy data and impact cards in the Tesla app. Self-Powered mode approximately doubles the amount of solar energy that powers your home by storing it for use at night. Similarly, when you consume more power than what’s available from your solar system and stored in Powerwall, you will import power from the grid. When you produce enough solar power to offset your home’s current consumption and Powerwall is fully charged, any excess solar power will export to the grid. Your Powerwall will charge when excess solar power is produced, and this stored energy will be used when your home requires more power than your solar system can provide. When Self-Powered mode is selected, your Powerwall stores solar energy not used during the day to power your home at night. Setting a higher reserve percentage saves more energy for protection during an outage, while setting a lower reserve percentage allows optimized performance when in Self-Powered or Time-Based Control mode. Note: Consider your personal economic needs and energy security outlook when setting Backup Reserve. To learn more about this behavior, visit Best Practices During Power Outages. In the morning, your Powerwall will periodically provide power to your home until there is enough solar power available to both power your home and recharge itself. If a grid outage occurs while your Powerwall’s stored energy is below 5%, you will immediately lose power to your home, and Powerwall will save this energy and wait to recharge itself via solar the next morning. If you set your reserve percentage below 20%, a ‘Low Backup Reserve’ indicator will be displayed, and your Powerwall may not have enough stored energy to provide backup support during an extended grid outage.
Note: Setting a backup reserve of 100% negatively impacts your economics and increases your reliance on the grid. You may use Powerwall as a backup-only appliance by selecting Self-Powered mode with a Backup Reserve of 100%. When the outage is resolved, your Powerwall will prioritize charging above your reserve percentage before resuming normal operation.
With Backup Reserve, your Powerwall provides you with energy security during a grid outage. Systems Affected by Natural Disaster or Force Majeure Event.Transferring Ownership of Your Solar System.
