Tesla Powerwall 3

Not yet, but Tesla has announced that a software update is coming soon that will make the Powerwall 3 compatible with the Powerwall 2. Once that's live, we'll be able to add a Powerwall 3 to your existing Powerwall 2 set-up.

Yep, fully eligible for the federal Cheaper Home Batteries Program. The rebate's applied upfront as a discount on your quote, so you only pay the net amount. We handle every bit of the paperwork. Tesla's own limited-time cashback rebate (up to $1,500) stacks on top as well, which Tesla pays out after install.

At Tesla's Gigafactory in Nevada, USA, the same facility Tesla uses to build its other battery products. Over a million Powerwalls have now come out of it globally.

Yes, but if you're home during the day, your smartest play is to charge during the day so you can save your evening battery capacity for the house. If you're mostly charging overnight, you might need more battery capacity than a single Powerwall holds, so you could potentially look at adding additional module(s). This is something we can work through with you when we do your quote. Tesla also makes its own home EV charger: pair it with a Powerwall 3 and your solar, battery, home and car can all live seamlessly integrated in the same app.

Yes. You can pair a Powerwall 3 with up to three Powerwall 3 Expansion units, giving you a total of 54 kWh of usable storage. The Expansion units are battery-only (they piggyback off the inverter in the main unit), which keeps the cost down. Worth doing if you've got a big home, high evening usage, or you're thinking ahead about EV charging.

Ten years, parts and labour, direct from Tesla. The battery's guaranteed to retain at least 70% of its original usable capacity at the 10-year mark under standard residential use (solar self-consumption, time-of-use, and backup).

A typical residential install is one day, with a team of two. More complex jobs (long cable runs, multiple Powerwalls, three-phase switchboards) can take a bit longer. We'll give you a clear timeline when we book the job.

Yes. The Powerwall 3 has a solar inverter built in, so most installs either replace your existing inverter (worth doing if it's getting old) or run alongside it as a battery-only solution. Which option makes more sense depends on the age and condition of your current setup. We'll work it out in your free quote.

Yep, and well. The Powerwall 3 is designed to support full-home backup, and it can deliver up to 11.04 kW continuously. Really big homes with heavy draw might need an additional Powerwall unit or two to keep everything running, but for most Aussie houses one is plenty. Switchover when the grid drops is fast enough that most appliances won't even blink.

A lot. The Powerwall 3 has a solar inverter built in (the Powerwall 2 didn't), more than double the continuous power output (11.04 kW vs 5 kW), three solar inputs for flexible roof layouts (the Powerwall 2 was AC-coupled only), and a switch from NMC to safer, longer-lasting LFP battery chemistry. The Powerwall 2 is no longer sold in Australia. If you're getting a new Powerwall in 2026, it's a Powerwall 3.

It depends. Every home's different: your existing solar setup, where the battery's going to live, your switchboard, your state, they all move the number around. The best move is to get a free quote and we'll give you a real one customised for your home. The federal rebate is baked into your quote upfront as well.
