The Tesla battery revolution continues in 2025, with the launch of the much-anticipated Tesla Powerwall 3 in Australia. As energy prices fluctuate and demand for clean, reliable backup power rises, the Powerwall series—particularly the new model—promises smarter energy storage for modern Aussie homes.

In this in-depth review, we explore how the Tesla battery lineup has evolved from the Powerwall 2 to the upgraded Powerwall 3, and what that means for your energy bills, ROI, and energy independence.

• Seamless backup power during outages

• Time-based control to optimise electricity costs

• Sleek wall-mounted design

• Integration with Tesla's mobile app for real-time monitoring

Tesla introduced the Powerwall 2 in 2016, and it quickly became one of the most popular home batteries in the world. Now, with the Powerwall 3, Tesla is raising the bar for power output, scalability, and whole-home backup functionality.
