Powerwall 3 supports up to 20 kW DC from solar inputs and delivers up to v c v11.5 kW AC of continuous output per unit. It is capable of initiating heavy loads with ratings up to 185 LRA, allowing a single unit to meet the power demands of most residences. Designed for quick and effective installations, Powerwall 3 facilitates modular expansion and easy integration with any electrical setup.
Benefits of your Tesla Powerwall
Powerwall 3 is a fully integrated solar and battery system, designed to accelerate the transition to sustainable energy. Customers can receive whole home backup, cost savings, and energy independence by producing and consuming their own energy while participating in grid services and virtual power plants. Once installed, customers can manage their system using the Tesla App to customise system behaviour to meet their energy goals.
Powerwall 3 achieves this by supporting up to 20 kW DC of solar and providing 11.5 kW AC of continuous power per unit. It has the ability to start heavy loads rated up to 185 LRA, meaning a single unit can support the power needs of most homes. Powerwall 3 is designed for fast and efficient installations, modular system expansion, and simple connection to any electrical service.
Powerwall is compact, safe and includes a built-in battery inverter, which provides easier integration and over-the-air updates for new features and functions

Features - Tesla Powerwall 3
Power Everything
Powerwall reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. Use Powerwall alone or combine it with other Tesla products to save money, reduce your carbon footprint and prepare your home for power outages. In addition, Tesla operates Australia's largest Virtual Power Plant, a network of homes to support the grid with clean renewable energy.

Typical System Layouts
Whole Home Backup
A Powerwall 3 system for whole home backup is designed to store energy from the grid or solar, and power the entire home during a grid outage.
Partial Home Backup
A Powerwall 3 system for partial home backup is designed to store energy from the grid or solar, and can power some home loads during a grid outage. These loads are selected during the system design phase, and the installer configures the system at installation to exclude all other loads from backup.

Frequently Asked Questions
-
Tesla mobile app - log in / set up / learn more
Once your Powerwall has been turned on, download the Tesla app and start monitoring your Powerwall and home energy usage.
Step 1: Log In
Log in using the same email address you used to order Powerwall with solar. If you are already a Tesla vehicle owner, log in using the same email address you use to sign into your Tesla Account.Step 2: Set Up Notifications
Receive notifications when Powerwall starts backing up your home during instances such as a power outage.Step 3: You are now logged into the Tesla app
Learn more about the features of the Tesla mobile app. You can also learn more about using and customizing your Powerwall below: -
Why does the Tesla mobile app show power flows or values that appear inaccurate?
Power flow on the monitoring Tesla mobile app shows the instantaneous flow of power of your home energy system. On a typical day a combination of solar, grid, and Powerwall may be powering your home. Solar energy may flow to the grid when your home does not need it and Powerwall is full. When charging your Powerwall to its backup reserve level or in Backup-only mode, solar power will flow directly from solar to Powerwall while grid energy is drawn for the home.
-
Where can I find my Powerwall Gateway information?
The Tesla Gateway part number and serial number for your Powerwall Gateway will appear on a sticker on the inside of the Gateway door. Learn how to locate your Gateway information here.
-
Why isn't my Powerwall charging?
When installed with PV, Powerwall is designed to charge from solar energy. If your solar system is not yet operational, Powerwall will not be able to charge. If your solar system is operational and you are in Self-powered Mode, Powerwall will charge with any excess solar that your home doesn't immediately use. Smaller solar systems sometimes do not produce more than your home is currently using. You can increase the backup reserve or switch to Backup-only, which will prioritize charging Powerwall with any solar production.
-
How much does it cost to go off-grid?
The cost to go off-grid will depend on your expected/anticipated energy demand. With knowledge of your energy demand we can then help you size your battery storage, solar PV, generator, microgrid inverter, etc.
It is worth noting that connecting a new block to the power grid can cost between $15,000 and $50,000 depending on the situation. And a typical energy bill for the average household is around $3000-$4000 per year (or higher in colder areas). Given the cost of grid connection and supply, a well maintained and high quality off-grid system is likely to be cheaper in the long run (20 years +), depending on your particular situation (if grid connection is >$30,000 you can pretty much assume off-grid will be cheaper).
