How Powerwall Works
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.
Tesla Powerwall 3 Review
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:
- Massive 13.5kWh Usable Energy Storage
- Seamless Solar Integration with Built-in Inverter
- Smart App Control & Monitoring from Anywhere
- Reliable Backup Power During Blackouts
- Lower Electricity Bills and Grid Dependence
- Durable, Weather-Resistant Design for Australian Conditions
- Faster, Cleaner Installation Process

Stay in Control with the Tesla 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.
How much does a Tesla Powerwall 3 cost?
In 2026, the Tesla Powerwall 3 costs around AUD $11,900, and the Backup Gateway 2 is about AUD $1,950. This means the total price for the equipment (Battery + Backup Gateway 2) is around AUD $13,850. Installation costs can be between AUD $1,000 to $3,000 (include Backup Gateway 2), depending on location, site conditions and the type of home. So, the full price to buy and install a Tesla Powerwall 3 is usually between AUD $14,850 to $16,000 (include installation). This battery gives you 13.5 kWh of usable energy storage capacity for your home.
A 40.5kWh Tesla setup typically means a Powerwall 3 (13.5kWh) with two Expansion Packs (27kWh). The battery-only price for the 40.5kWh setup is approximately AUD $35,700, while the total installed price usually ranges between AUD $42,000 to $46,000, depending on installation complexity and site requirements.
👉 After the Australian Federal Government home battery rebate from 1 May 2026, the Tesla Powerwall 3 (13.5kWh) battery price is approx.

In a direct comparison, the Tesla Powerwall 3 outperforms the Tesla Powerwall 2 in most areas, except for scalability. Powerwall 2 can be expanded up to 10 units (around 135 kWh total), while Powerwall 3 supports up to 3 units (40.5 kWh). However, since most Australian homes use roughly 15 kWh per day, such a large capacity isn’t necessary for most people.
For most buyers, the choice comes down to one thing: inverter setup. Powerwall 3 includes a built-in inverter for a simpler, all-in-one system, whereas Powerwall 2 relies on an external inverter—making it a better fit if you already have solar installed.
