What is the Tesla Powerwall?
The Tesla Powerwall is a high-tech battery storage solution that stores your solar energy for backup. It can automatically detect outages and then will recharge automatically to keep your appliances running. The Powerwall is made to last with its 10-year warranty and weather rating of -4° to 122° Fahrenheit.
Monitor and Customize Your Energy Consumption for Savings
Automatically detects power outages and uses stored solar energy
Kid and pet-friendly with no exposed wires or heating vents
The Powerwall is a lithium-ion battery storage solution that has a 13.5 kWh storage capacity with continuous on-grid power of 5.8 kVA. This allows one Powerwall the means to back up your essential loads. Tesla recommends one Powerwall for your essential loads and at least two Powerwalls to back up your whole home. They can be mounted either inside or outside on the wall or floor.

With the Tesla mobile app, you can get an overview of your home's energy consumption that details how much power you are using, and how much of that is created by your solar system.
1. The Backup Reserve feature allows your Powerwall to provide stored energy production during a grid outage by adjusting the slider shown in the settings picture. A reserve percentage of 20% is recommended and in the event of a grid outage, your Powerwall will always provide backup protection to your home with all of the energy that it has available - not just the reserve percentage.
See when you produce the most power to optimize your energy control settings. There are four different control modes you can utilize to change how the Powerwall charges and discharges.
Minimize your carbon footprint and become energy independent.
Time Based Control
Lower your utility bill by using your stored energy at specific times if your energy prices varies throughout the day.
Set up your powerwall to react to weather events that could cause a grid outage and start charging your battery in advance.
Vehicle Charging During Grid Outage
Use your Powerwall and Tesla vehicle(s) to balance your charging and energy needs when the grid goes down.
2. You can view what time your system starts producing daily, view your monthly usage, and get detailed system data for further analysis via the 'Energy' screen. The 'Impact' screen allows you to view how self-powered your home is, how much solar offsets your usage, and when your last grid outage was.
3. The home screen of the Tesla app allows you to view the flow of energy in your house between the Powerwall, your solar system, your home, and the grid.
