How Much is the Tesla PW3 in Australia?

The Tesla Powerwall 3 has not yet been released in the Australian market, so we don't have a confirmed Australian price. However, the Powerwall 3 has been released in the U.S and can be ordered for installation right now.

According to pricing estimates through Tesla's order page, Powerwall 3 costs around $10,000 (AUD) for the unit itself, which doesn't include the Gateway which will be needed in Australia, and the installation costs of the entire system.

Tesla Powerwall 3's Built-in Solar Inverter

With Tesla's inclusion of a built-in inverter, it saves you the need to spend money on a separate inverter for your solar system, and it also reduces the time to install your system with one less part to mount and connect.

If the Powerwall 3 release price is similar to the Powerwall 2, it will be great value for customers as an all-in-one-solution.

Each Powerwall 3 inverter has the capability to support 6 solar panel strings in order to allow for different shaped roofs and shading situations and has a maximum capacity of 20kW of solar.

Why is Elite Power Group looking forward to the Tesla Powerwall 3?

Elite Power Group are looking forward to the Tesla Powerwall 3's release in Australia for a few reasons:

Simpler Installation

The Powerwall 3 has a simple installation process compared to its predecessor, the Powerwall 2. Because of the built-in inverter, it allows installers (like us) to have a simpler process when installing a Powerwall 3 to a home or business, which saves us time and you money.
One Powerwall 3 can allow for up to 20kW which is more than enough for the standard home which sits around 7kW of solar.

Higher Power Output

Because of its impressive power output, it is more flexible for homes with high power requirements. 
The Powerwall 3 will be able to start up high-consumption appliances, and power the entire home with backup energy.
In comparison to the Tesla Powerwall 2, the Powerwall 3 offers for greater whole-home support and reliability in high demand periods.

Quality & Reliability

We genuinely love Tesla and their products.
Our installers recommend Tesla products as they are well-refined and reliable in what they're designed for.
The Elite Power Group team have been installing Powerwall 2's since their release and continue to push them out as they are high quality and long-lasting. We expect the same for Powerwall 3 and can't wait to get our hands on one.

Certified Tesla Powerwall Installers Newcastle & Hunter

Should you wait for a Powerwall 3 vs. Powerwall 2?
Whilst both batteries are very useful, the Powerwall 3 is more designed for newer homes with no solar, whereas the Powerwall 2 is designed for retrofitting storage into existing systems.

Our team have invested in becoming trusted Tesla installers to allow business and homeowners to take advantage of Tesla's newest technology, benefiting your homes' solar, energy independence, and your wallet. We want to see homes excel in their energy production and consume sustainable energy with smart energy management.
