Looking for a long-lasting and reliable home battery storage solution? Meet Tesla Powerwall 3 – smarter, stronger, and better than its predecessors. With Powerwall 3 joining the lineup, a fresh new champion in Tesla’s chart-topping lineup of energy storage devices, come outstanding advantages that aim to maximize solar savings, provide dependable backup power, and pre-prepare homes or business locations for anticipated electricity price increases.
At Aussie Solar Tech, we’re proud to supply and install the Tesla Powerwall 3 across Australia, helping homes and businesses achieve true energy independence.
Powerwall allows energy storage for later usage and works with solar energy for some critical energy security and financial benefits. Each Powerwall system is enabled with energy monitoring and metering and smart controls for owner customization through the Tesla app. The system learns and adapts to your energy use over time and receives over-the-air updates to introduce new features and improve existing ones.
In late 2023, one could see numerous articles and pictures of the Tesla Powerwall 3 circulating on the internet. Soon after, Tesla officially unveiled the new Powerwall 3, and finally, the official datasheet was uploaded to the documents section of Tesla’s website in February 2024. Unlike Powerwall 2, which is an AC-coupled battery system, the new generation Powerwall 3 is an all-in-one solar and battery energy storage solution, seemingly similar to the Powerwall+ (Plus) launched in 2021 in the US but smaller and much more powerful. However, despite integrating a solar inverter and battery storage into one elegant box, the new Powerwall 3 still needs other components to unlock its full power.
The Powerwall 3 has an increased capacity, integrated features, and a sleeker design, building on the legacy of its predecessor. For Australian solar owners, here below is why the Powerwall 3 truly will be a game-changer:
| Feature | Specification |
| Energy Capacity | 13.5 kWh1 Additional energy capacity with Powerwall 3 Expansion |
| On-Grid Power | 11.5 kW continuous |
| Backup Power | 11.5 kW continuous 185 LRA motor start Seamless backup transition |
| Scalable | System expansion available anytime 40.5 kWh max addition per unit |
| Size and Weight | 43.5″ x 24″ x 7.6″ 287 lbs |
| Integrated Inverter | Yes |
| Installation | Integrated inverter and system controller -4°F to 122°F Flood and dust resistance2 |
| Warranty | 10 years |
| Dimensions | Compact, modern design |
| App Control | Tesla Energy app |
Tesla’s smartphone app allows real-time monitoring and control for the Powerwall 3, where you can see energy production, storage, and consumption in real time. Through the app, you can modify energy usage by selecting different operating modes, such as setting a priority for backup power or setting a maximum self-consumption.
The app functionality on Powerwall 3 is largely identical to what it was before, with features like remote adjustments and updates from Tesla itself included. None of the salient new features in the app have anything to do with Powerwall 3 itself, so those experienced on Powerwall 2 won’t have a problem familiarizing themselves with similar functionality here. The app continues to be an effective tool for managing your home energy system.
Here’s a table comparing the three Powerwall models:
| Powerwall Models | Powerwall 2 | Powerwall + | Powerwall 3 |
| Energy Capacity | 13.5 kWh | 13.5 kWh | 13.5 kWh |
| On-Grid Power | 5 kW continuous | 5 kW / 7.6 kW continuous | 11.5 kW continuous |
| Backup Power | 7 kW peak 106A LRA motor start Seamless backup transition | 9.6 kW / 7 kW continuous 22kW / 10kW peak 118A LRA motor start Seamless backup transition | 11.5 kW continuous 185 LRA motor start Seamless backup transition |
