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 Eco Energy Solutions team can install a DC-coupled Powerwall 3 to seamlessly pair the Tesla inverter to your panels.

How many Powerwalls will I need for my solar installation?
If a customer has an existing solar installation and wants to add a battery, the max AC system size per Powerwall 3 unit is 7.68 kW. If they have over 7.68 kW of solar installed, the property owner will need multiple Powerwall units. The max DC Coupled Input for the PW3 is 20kW DC. It is possible to have 7.68 kW AC Coupled with up to 20kW DC at the same time per PW3 unit.
Can I pair my Powerwall 2 with the new Powerwall 3?
No. Since previous Powerwalls harnessed separate inverters, the AC-coupled Powerwall 3 will work in sync with your current system, however, there are two additional conversions. The energy moves from DC in your panels, to AC in your existing inverter, then is converted back to DC by the integrated Tesla inverter and stored as DC in the battery, then converted back to AC to power your home.
