Mobile App Overview

What can I use Powerwall for?

Powerwall can be used for a variety of applications, including:

Self-Powering your Home

With Powerwall you can use more of your solar by storing the excess energy and using it at night, which roughly doubles the amount of solar energy that directly powers your home.

Backup Power

Powerwall provides seamless backup power in the event of a utility power outage. In a longer outage, Powerwall can recharge from your solar power system. If necessary, you can even run your home from solar and Powerwall indefinitely.

Home Energy Monitoring

You can monitor your solar, Powerwall and home energy use in real time with the Tesla app.

Time-based Control

If your electricity prices vary during the day, you are probably using a time of use (TOU) rate plan. On this plan, Powerwall can help you maximise the value of your solar and energy usage by smartly charging and discharging based on the time and price of energy.

How can I control Powerwall?

The Tesla app allows you to manage all of your Tesla products anytime, anywhere. With the Tesla app, you can choose between different modes, such as Backup-only or Self-powered. In Self-powered mode, you can reserve a percentage of your Powerwall for an outage. As with all Tesla products, we will continue to add new features and modes over time.

How can I monitor Powerwall operation?

As long as your Powerwall is connected to the internet, you will be able to use the Tesla app to monitor your home energy system in real time and view your energy usage history. During a grid outage, internet is often still available and you will be able to view Powerwall status. If the Internet connection is lost, Powerwall will continue to operate with its most recent settings but you will not be able to monitor operation or change settings until connectivity is restored.

Can Powerwall work without Internet? 

Powerwall needs an Internet connection (over wired Ethernet or your home Wi-Fi) or a cellular connection to receive software updates and to communicate with the Tesla app for energy monitoring. A reliable connection is required to provide new product features over time. If its connection is temporarily lost, Powerwall can continue to operate with its most recent settings, but it should not be installed in a location without Internet or cellular service.

How do I download and set up the Tesla mobile app?

The Tesla app is available on the iTunes and Google Play stores. You can download the Tesla mobile app from your regular app store on your device. Log in using your Tesla account information and you will see all your Tesla products in one place.

Do you have a tutorial on how to use the Tesla app?

Yes, you can view the video walkthrough above for a tutorial of the Tesla app.

What is the Power Flow in the app?

Power Flow shows real time power generated from your solar system, stored/discharged by Powerwall, used by your home, and exported/imported from the grid. It can be accessed from the Powerwall home screen. You will have real-time visibility into your home energy system.

How do I see energy usage history?

From the Power Flow screen, select any power source, or the bar chart icon on the top right, to access the graph page. From there you can select 'Today' to change the time period and access more data.

How can I change Powerwall's operating mode?

From the Powerwall home screen, select 'Customise.' From here you can select your mode of operation. Use Backup-only mode if you would like to keep all of Powerwall's capacity for a utility outage, or Self-powered if you would like to store excess solar energy for use at night. When in Self-powered mode, you can scroll down to set your backup reserve to keep a portion of Powerwall capacity for a utility outage. For a balance of backup protection and a Self-powered home, try setting your backup reserve so that your Powerwall reaches full charge just as the sun is setting each day.

Is there a website where I can monitor my Powerwall from my desktop computer?

At this time, you can only monitor your system via the Tesla app.
