The Tesla Backup Battery gives you the ability to store energy for later use and works with or without solar to provide key security and financial benefits. This guide is to help you understand how your backup battery works with your solar system and how to properly use the Tesla app to monitor your power wall.

It provides backup power protection

Battery storage makes sure your solar system will be able to operate and continue to provide clean power when the power goes out.

Your solar energy system is used efficiently

A battery helps store excess solar power so you can use it in the evening once the sun goes down. You can also use a battery to help offset using power from the grid when energy rates are higher.

Cleaner energy usage

When you have solar and battery together, it means less demand for grid power when grid energy sources are associated with the most greenhouse gas (GHG) emissions.

Each Powerwall can hold up to 13.5 kWh of energy. To put that into context, a central 3-ton AC unit running for constantly 3 hours will use 9 kWh. Of course, a well designed cooling system will not run for three hours straight — it turns off and on intermittently to maintain the desired temperature.

Depending on your home’s typical energy usage, multiple Powerwalls may provide beneficial coverage during outages.

This quick guide is to begin the activation and use of your new Powerwall. Prior to installation, you will need to download the Tesla App from your app store onto your smartphone. Setting up your Tesla Phone App will allow you to monitor your home battery and solar production, giving you complete control of the way your energy is used.

The Tesla app allows you to manage your Powerwall and allows A.M. Sun Solar to modify or change the settings for you with the use of your phone. The app will set up how you want to charge and discharge the battery.

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