Why people choose Tesla Powerwall

  • Built-in solar inverter keeps the install tidy, with no separate hybrid inverter needed for a Powerwall-only system.
  • Whole-home backup capability, so your circuits, or the whole house, can stay powered through an outage.
  • The Tesla app gives clear, real-time monitoring and control from your phone.
  • Eligible for the federal battery discount and most state incentives.

Tesla Powerwall cost after rebates

The headline price matters less than the after-rebate price. The federal Cheaper Home Batteries discount takes roughly 30% off an eligible Tesla Powerwall battery, and your state incentive is separate, where one applies.

How much does a Tesla Powerwall cost in Australia?
After the federal rebate, a Tesla Powerwall 3 typically lands around $10,000 to $13,000 installed, depending on your switchboard and whether you add whole-home backup. See our full Powerwall guide for the details, or we confirm your exact after-rebate price by postcode.
What is the difference between the Powerwall 2 and Powerwall 3?
The Powerwall 3 is Tesla’s current model, with a higher-output built-in inverter and a simpler install than the older Powerwall 2. Most installers now quote the Powerwall 3, since the Powerwall 2 is largely out of production in Australia.
Does the Tesla Powerwall battery qualify for the rebate?
Eligible Tesla Powerwall batteries qualify for the federal Cheaper Home Batteries discount, and most states run a separate incentive too. We work out the federal discount and any state incentive as two real numbers, never merged.
Will you only quote me one brand?
We stay brand-neutral. We match you with one vetted installer who recommends the battery that genuinely fits your roof, usage and budget, whether that is this brand or another.
