Building on the success of its earlier versions, the new Powerwall 3 introduces several key improvements that shows Tesla’s commitment to enhancing energy independence and sustainability for homeowners. The updated design of the Powerwall 3 simplifies installation, making it faster and more straightforward for homeowners and installers. It also comes with an integrated inverter designed to increase efficiency when using and storing power.
The biggest upgrade in the new Powerwall involves its 11.5 kW of continuous power output. Compared to the 5 kW of the current Powerwall 2 and the 5.7 kW of the Powerwall+, this new iteration of the most popular solar battery on the market takes home energy storage to the next level. The Powerwall 3 protects you from outages at any time of day, as well as time-of-use rate changes and net metering changes.
If you already have a rooftop solar installation, the new AC-coupled Powerwall 3 should pair well with your existing inverter setup by including a Tesla Gateway. Alternatively, the Good Energy Solutions team can install a DC-coupled Powerwall 3 to seamlessly pair the Tesla inverter to your panels.
