Australians have been waiting to find out when they can get their hands on their own Powerwall 3. Since news of the new edition of Telsa’s Powerwall series was confirmed in September 2023, we’ve been keeping our ears to the ground. Tesla has added snippets of information to their website and the Powerwall 3 is now available for installation in the continental United States.
Let’s look at when we can expect them in Australian homes and how much we can expect to pay.

What will be the cost of the Tesla Powerwall 3?
While not set in concrete, it is expected that the Powerwall 3 will cost the same as the Powerwall 2. This will bring the pre-installation cost of the Powerwall 3 to AU$10,400. This price will also not include the Tesla Gateway.
The Tesla Gateway (an additional AU$1,700) will be required as it controls the connection to the grid, safely disconnects your home, and starts backup operation during an outage.
What is the Tesla Powerwall 3?
The Tesla Powerwall 2 is one of the most popular home battery storage units installed across the world. Its predecessor, the Powerwall 1, was quickly replaced by the Powerwall 2. The OG Powerwall entered the market at a whopping 10kWh but was only good for 500 cycles. The Powerwall 2 stepped in at a reduced 7kWh of storage but was manufactured to last 10 years and serve as a daily backup source of energy. The Powerwall 2 now boasts 13.5kWh of usable energy with 10 years of ‘unlimited cycles’.
As with any new technology, the general public now expects upgrades. The Powerwall 3 is the next evolution in the Powerwall series.
Tesla battery comparison
Let’s compare the Powerwall 2 to the 3.
| Specification | Tesla Powerwall 2 | Tesla Powerwall 3 |
|---|---|---|
| Storage capacity | 13.5 kWh | 13.5 kWh |
| Maximum continuous discharge power | 5kW | 11.5kW |
| Maximum continuous charge power | 5kW | 5kW |
| PV Inverter | No | 11.5kW inverter with 6 MPPTs |
| Operating temperature | -20°C to 50°C | -20°C to 50°C |
| Weight | 114kg | 130kg |
| Dimensions | 1150 x 753 x 147 mm | 1099 x 609 x 193 mm |
| Grid voltage range | 211 V – 264 V | 211 V – 264 V |
| Ingress rating | IP 67 (Battery & Power Electronics)IP56 (Wiring Compartment) | NEMA 3R (IP unknown) |
| Warranty | 10 years | 10 years |
While the storage capacity remains the same, the Powerwall 3 comes with two features that pip the Powerwall 3. 11.5kW of continuous output power allows your home to draw more from the battery at any one time. This will be invaluable during a blackout event as you will be able to run more appliances at once.
But the real icing on this electrical cake is the inclusion of an 11.5kW inverter with 6 MPPTs. This means that a home can opt to install a Powerwall 3 and up to 20kW of solar panels with no additional inverter required. The included 6 MPPTs will also allow for up to 6 strings, which is an incredible feature. The inverter will be capped at 5kW of continuous charge from the solar panels.
Can I add the Powerwall 3 to my existing Powerwall 2?
The Tesla website explicitly states that the Powerwall 3 cannot be retrofitted to an existing Powerwall 2 set-up. The Powerwall 3 is intended to be installed as a new solar installation. However, it is expected that a retrofit will be possible in the future with software upgrades. Until such a time, only Powerwall 2s can be added to existing Powerwall 2 installations.
The Tesla Powerwall 3 can be added to an existing solar system without battery storage.
Will I be able to install more than one?
Powerwall 3 installations will be expandable. While not confirmed, it is expected that expansion packs without the integrated inverters will be available. This should mean that the additional storage components will be cheaper than the base Powerwall 3.
Can I order the Tesla Powerwall 3 in Australia?
You can now order the Tesla Powerwall 3 for installation in Australian homes. As this is a new product on Australian shores, wait times may be associated with the order and installation. We recommend getting in quick to order as history has shown that wait times can be blown out to months.
