What’s New with the Tesla Powerwall 3?

The Tesla Powerwall 3 in Australia is an all-in-one solar and battery energy storage system, designed to integrate seamlessly with solar panels. Unlike the Powerwall 2, which is AC-coupled, the Powerwall 3 combines a solar inverter and battery storage into a single, compact unit. With its official datasheet now available, the Australian version showcases unique configurations tailored to local regulations, such as three high-powered 6.6kW solar Maximum Power Point Trackers (MPPTs).

Key Features

The Powerwall 3 specs reveal a system built for performance and scalability. Here are the standout features:

  • Type: All-in-one solar and battery system (DC-coupled solar).
  • Capacity: 13.5kWh, the same as the Powerwall 2.
  • Scalability: Expandable to 40.5kWh with two additional 13.5kWh DC battery units.
  • Power Rating: 11.04kW continuous output in Australia.
  • Solar Input: Up to 20kW of solar via three MPPTs.
  • Weight: 130kg.
  • Warranty: 10 years.
  • Price: Starting at AUD $13,600, including the Backup Gateway 2, but excluding installation.

This new model is a step forward in terms of functionality and performance, though it requires additional components to reach its full potential.

Tesla Powerwall 3 vs. Powerwall 2

The comparison of Tesla Powerwall 2 vs 3 highlights several key differences:

  • Solar Integration: The Powerwall 3 integrates a solar inverter, whereas the Powerwall 2 requires an external one.
  • Power Output: The Powerwall 3 offers slightly higher continuous power output (11.04kW vs. 5kW for the Powerwall 2).
  • Scalability: While both models support the same battery capacity per unit, the Powerwall 3’s advanced design makes expansions more seamless.
Australian Adaptations

The Tesla Powerwall 3 in Australia is specifically modified for local standards, with a slightly reduced power rating compared to the US version. Additionally, the three MPPTs in the Australian model handle higher currents, providing compatibility with local solar setups.

Tesla Powerwall 3 Storage Capacity and Price

The Tesla Powerwall 3 storage capacity remains at 13.5kWh per unit, matching the Powerwall 2. However, its expanded scalability makes it ideal for households with larger energy demands. While the price in Australia is approximately AUD $1,500 higher than the Powerwall 2, the enhanced features and potential energy savings make it a worthwhile investment for many homeowners.

Final Thoughts

The Tesla Powerwall 3 in Australia solidifies its reputation as a market leader in energy storage solutions. Featuring an innovative design, enhanced capacity, and seamless integration capabilities, the Powerwall 3 emerges as a top choice for individuals seeking to adopt renewable energy and minimise reliance on the traditional power grid.

Powerwall 3: When It Makes Sense and When It Doesn’t

Powerwall 3: When It Makes Sense and When It Doesn’t

Powerwall 3: When It Makes Sense and When It Doesn’t

The Tesla Powerwall 3 is the latest iteration of Tesla’s innovative home battery system, designed to store energy generated by solar panels or the grid. It is a game-changer in renewable energy technology, but like any product, it has its advantages and limitations. 

For homeowners considering the Tesla Powerwall 3 in Australia, this guide will help you understand when it makes sense and when it might not.

When the Tesla Powerwall 3 Makes Sense

  • Maximising Solar Energy Usage: The Tesla Powerwall 3 in Australia is an excellent way to store excess solar energy generated during the day. This stored energy can power your home during the evening, reducing reliance on the grid and lowering electricity bills. 

  • Backup Power During Outages: Frequent power outages in some Australian regions make the Tesla Powerwall 3 a valuable asset. Its ability to store energy ensures your home remains powered even during grid failures, providing peace of mind in emergencies.

  • Improved Capacity and Performance: The Tesla Powerwall 3 capacity is larger than its predecessor, making it suitable for homes with higher energy demands. Its advanced lithium-ion technology ensures efficient energy storage and reliable performance, even for large households.

When the Tesla Powerwall 3 May Not Make Sense

  • High Upfront Costs: The Tesla Powerwall 3 in Australia comes with a significant upfront investment. While it can lead to savings over time, the initial costs may not be justifiable for households with low energy consumption or those without solar panels.

  • Suitability for Grid-Connected Homes: If you live in an area with stable electricity supply and relatively low energy rates, the economic benefits of installing a Tesla Powerwall 3 may be less compelling.

  • Size of Storage Needs: Understanding the Tesla Powerwall 3 storage capacity is crucial. While the new model offers improved storage compared to the Powerwall 2, smaller households may find the capacity underutilised.
