This downward trajectory culminated in the current price of $8,900, making it more accessible to Australian consumers seeking sustainable energy solutions.

High demand for Tesla’s Powerwall 2 in Australia, driven by increasing awareness of renewable energy benefits and government incentives, has significantly shaped its price dynamics. Additionally, improvements in production processes and supply chain optimisation have contributed to cost reductions, allowing Tesla to pass these savings on to consumers.

As Tesla continues to innovate and expand its presence in the Australian renewable energy market, the pricing of its energy storage solutions, such as the Powerwall 2, is expected to remain dynamic. Factors such as technological advancements, market demand, and production efficiencies will influence this.

How Tesla Powerwall 2 Works

The Tesla Powerwall 2 employs advanced Lithium-ion battery technology to store and efficiently distribute electricity for residential use. This technology, derived from the same principles used in electric vehicles and portable electronics, offers several advantages in terms of efficiency, capacity, and longevity.


  • Efficiency: Lithium-ion batteries, including those used in the Powerwall 2, are known for their high energy density. This allows them to store large amounts of energy within a relatively small footprint, resulting in greater efficiency in storing and discharging electricity. Thus, the Powerwall 2 is a compact yet powerful solution for residential energy storage needs.
  • Composition: The Powerwall 2’s Lithium-ion battery is composed of lithium compounds, typically lithium cobalt oxide, lithium iron phosphate, or a combination of various lithium-based compounds. These compounds are chosen for their stability, high energy density, and long-term reliability, ensuring that the Powerwall 2 delivers consistent performance over its lifespan.
  • Suitability for Large Residential Homes: The Powerwall 2 is well-suited for large residential homes due to its scalability and robust energy storage capabilities. With a storage capacity of up to 13.5 kWh, it can comfortably meet the energy demands of sizable households, including powering essential appliances during grid outages or periods of high electricity consumption.


Moreover, the Powerwall 2’s modular design allows homeowners to install multiple units in parallel, further increasing storage capacity to accommodate larger homes or higher energy usage patterns. This scalability ensures that the Powerwall 2 can adapt to varying household energy needs, providing reliable backup power and enabling greater self-sufficiency in energy consumption.

Backup Gateway for the Tesla Powerwall 2

The Backup Gateway serves as the central control unit for the Tesla Powerwall 2, ensuring seamless operation and reliability, particularly during power outages. Functioning as a bridge between the Powerwall 2 and the home’s electrical system, the Backup Gateway constantly monitors energy flow and grid conditions, enabling swift transitions between grid-connected and standalone modes. 

During regular operation, the Backup Gateway optimises energy usage by intelligently managing the electricity flow and prioritising renewable energy sources and stored power from the Powerwall 2.

In a grid outage, the Backup Gateway automatically detects the disruption. It swiftly switches the Powerwall 2 to backup mode, ensuring an uninterrupted power supply to critical appliances and systems in the home. This seamless transition allows homeowners to maintain essential services, such as lighting, refrigeration, and heating, even in adverse conditions. 

While the Backup Gateway enhances the resilience and reliability of the Powerwall 2 system, it typically incurs an additional cost beyond the base price of the Powerwall 2 unit. However, its peace of mind and increased energy independence make it a valuable investment for homeowners seeking to mitigate the impact of power outages and embrace sustainable energy solutions.
