Last Chance To Get Tesla Powerwall 2: Australia's Most Popular Battery Storage

Save Up to $2,400 With The NSW Battery Rebate

Do You Have An Existing Powerwall 2? Final Units Left: Last Chance to Expand Your System

The Tesla Powerwall 2 is being discontinued soon. If you’re looking to expand your energy storage, here’s what you need to know: the Powerwall 2 and Powerwall 3 are not compatible. To increase your storage capacity with an existing Powerwall 2, you’ll need to add another Powerwall 2.

With energy usage rising in Australian homes, now is the time to act. Secure your Powerwall 2 before stock runs out and future-proof your system.

Support and warranties for the Powerwall 2 will still be available after it's discontinued.

Final Powewall 2 Units Available

We're down to our final Powerwall 2 units, and once they're gone, they're gone for good! Whether you’re looking for system expansion or just a powerful and reliable solar battery to elevate your energy independence, now is the time to install your Powerwall 2.

Enjoy Bigger Savings Sooner

Don’t pay extra for features you don’t need. If you already have solar panels, Tesla Powerwall 2 is the best value battery for you. More sun means greater power generation, more energy stored and putting all of that together - more savings.

Already Have an Existing Solar System?

The Powerwall 2 is the solar battery for you.

Why pay for components you don't need? The new Tesla Powerwall 3 features a built-in inverter. While this is great, if you already have a solar system installed then you don't need the added built in solar inverter, you already have one! For solar homes looking for battery storage, the Powerwall 2 is the BEST value battery on the market.
