Tesla Powerwall is a fully-integrated AC battery system for residential or light commercial use. Its rechargeable 13.5kWh lithium-ion battery pack provides energy storage for solar self-consumption, time-based control, and backup.
Powerwall’s electrical interface provides a simple connection to any home or building.
Its revolutionary compact design achieves market-leading energy density and is easy to install, enabling owners to quickly realize the benefits of reliable, clean power.
How Does Powerwall Work?
Powerwall gives you the ability to store energy for later use and works with or without solar to provide key security and financial benefits. Each Powerwall system includes at least one Powerwall and a Tesla Gateway, which provides energy monitoring, metering and management for the system. The Backup Gateway learns and adapts to your energy use over time, receives over-the-air updates just like the rest of Tesla's products and is capable of managing up to ten Powerwalls.
When the sun rises, solar begins powering the home. When additional power is required within the home, the home can pull from the utility grid.
Powerwall is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage.
The next day when the sun comes out, solar recharges Powerwall so you have a cycle of clean, renewable energy.
If your electricity rates vary throughout the day, Powerwall will charge when electricity costs are low and discharge when electricity costs are high, generating automatic savings. Powerwall will also provide seamless backup power by detecting grid outages and automatically becoming the home's main power source.
