Official Specifications, Features, and Projected Price & Release date in Australia.
Tesla's new fully integrated solar and battery, designed to be a whole home backup system, accelerating return-on-investment on solar
systems, cost savings, and energy independence. With its built-in inverter, it's the all-in-one package for new homes and businesses.
Tesla has announced their new battery, Tesla Powerwall 3.
This battery has unique functionality, including a game-changing - built-in inverter, higher capacity, and more.
They have been relatively secretive about their release of the PW3, but have officially released the battery for installation in the
U.S.
There is still yet to be any information about Tesla Powerwall 3's release 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.
Powerwall 3 is more than just a backup battery. It can optimise your stored solar or cheap grid energy to charge your electric vehicle, run appliances, and just simply make a coffee with sustainable energy through the day, night, or grid outage.

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.
Below are the in-depth specifications and features of the Tesla Powerwall 3.
These are according to the official Tesla
Datasheet.

Like Powerwall 2, Powerwall 3 allows homes to be completely energy independent and unaffected in grid outages. When storms hit and grid energy fails, you can be assured your lights will stay on with Tesla's smart energy management.
Self-reliant, sustainable energy for your home.
Elite Power Group are looking forward to the Tesla Powerwall 3's release in Australia for a few reasons:
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.
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.
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.
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.
Elite Power Group are certified Tesla installers, specialising in Tesla product installation such as the Powerwall 2, Gateway, and Gen 3 Wall Connector charger.
