If your energy costs vary through the day, or if you are on a time-of-use rate plan, Powerwall can take that into account to maximise your savings. When electricity is expensive, Powerwall uses stored low-cost energy to power your home. Regional regulations may apply to the operation of Powerwall, which may vary some aspects of this mode.
Powerwall learns how you use energy
Powerwall has an array of electrical current sensors that monitor energy usage and solar energy production. Tesla’s intelligent forecasting software predicts future usage and production. Based on the varying cost of electricity from the grid, Powerwall optimises the times it charges and discharges. As Powerwall learns, you get the most value from your solar production without having to change how or when you use energy.
You can set up a schedule to let Powerwall know the times electricity is expensive (peak) and inexpensive (off-peak).
Existing Powerwall 2 owners will see this new feature rolled out via a firmware update over the coming weeks.
