Tesla Powerwall 3 Price Australia

As the Tesla Powerwall 3 gears up for its Australian release in the latter half of 2024, excitement is building among renewable energy enthusiasts. This next-generation solar battery and inverter combo promises to reshape home energy storage, but it also raises important questions about its suitability for the Australian market.

Tesla Powerwall 3: Key Features and Specifications

The Tesla Powerwall 3 integrates a robust 11.5 kW built-in inverter, significantly enhancing its appeal for new installations. It boasts a 13.5 kWh energy storage capacity and an impressive continuous power output of 11.5 kW, making it ideal for supporting high-demand appliances. Its six Maximum Power Point Trackers (MPPTs) allow it to manage up to 20 kW of solar panels, catering to households with significant energy needs.

Key Specifications

  • Continuous Power: 11.5 kW
  • Peak Power: 15 kW
  • Energy Capacity: 13.5 kWh
  • Dimensions: 1098 mm x 609 mm x 193 mm
  • Weight: 130 kg
  • Battery Chemistry: Lithium Ferro Phosphate (LFP)

Pricing and Cost Considerations

While Tesla hasn’t officially announced the Australian price, the Tesla Powerwall 3 is expected to cost around $10,400 (excluding installation and the $1,700 Backup Gateway). This price point mirrors the Powerwall 2, maintaining a competitive stance in the market. The inclusion of the hybrid inverter, valued between $2,000 and $3,500, offers substantial savings for new solar installations.

Pros and Cons of the Tesla Powerwall 3


  • Integrated Inverter: Simplifies installation, reducing the need for additional equipment.
  • High Solar Compatibility: Connects with up to 20 kW of solar panels.
  • Scalable Storage: Expandable up to four units for a total of 54 kWh.
  • Enhanced Power Output: Supports larger households and critical appliances during outages.
  • Bidirectional Charging: Future-ready with vehicle-to-home (V2H) integration.


  • Limited Charging Capacity: Charging is restricted to 5 kW, potentially underutilizing connected solar capacity.
  • Retrofitting Challenges: Designed more for new installations, posing difficulties for existing setups.
  • Separate Backup Gateway: Adds to the overall cost.
  • Compatibility Limitations: No direct compatibility with older Powerwall models.

Performance and Usability

The Powerwall 3’s 11.5 kW continuous power output marks a significant improvement over the Powerwall 2, which only offered 5 kW. This advancement enables the support of high-demand appliances, making it a robust solution for whole-home backup during outages. However, its 5 kW charging limit might not fully harness the potential of large solar arrays, leading to some inefficiencies.

Battery Chemistry and Longevity

Tesla’s switch to Lithium Ferro Phosphate (LFP) chemistry in the Powerwall 3 enhances safety and longevity, with the company promoting a capacity retention of 70% after 10 years. This change not only boosts durability but also aligns with environmental sustainability goals by eliminating cobalt from the production process.

Installation and Integration

While the Tesla Powerwall 3 shines in new installations, its integrated inverter could pose challenges for homeowners looking to retrofit existing systems. However, its DC-coupled battery expansion units offer a scalable energy storage solution, allowing homeowners to adapt their systems over time.

Incentives and Rebates

Australian homeowners can take advantage of various government incentives to offset the cost of the Powerwall 3. Programs like the Queensland battery booster rebate are designed to encourage renewable energy adoption, providing financial support for solar and battery installations.


As the Tesla Powerwall 3 prepares to enter the Australian market, it presents a compelling option for new solar adopters. Its robust features and integrated design position it as a leader in home energy storage. However, for those looking to retrofit existing systems, the Powerwall 2 might remain a more practical choice.

With its potential to reshape energy consumption and enhance home energy independence, the Powerwall 3 is set to make a significant impact. Homeowners, installers, and policymakers alike will be watching closely as Tesla’s latest innovation arrives on Australian shores, heralding a new era in renewable energy solutions.
