When it comes to batteries, Tesla is the front runner, but do you wait for the powerwall 3, or get the 2?


  • Powerwall 2 and Power 3 share same total capacity.
  • Continuous output for the Powerwall 2 is 5kW, but the Powerwall 3 is 11.5kWh.
  • The choice boils down to how much you will be electricity you’re going to be using at once.
  • Tesla Powerwall 3 is anticipated to come to the Australian market, but probably not anytime soon (like the Cybertruck & Roadster 👀).

In the ever-evolving landscape of residential energy storage, Tesla continues to be a leading force with its groundbreaking Powerwall series. In this exploration, we’ll conduct a detailed comparison between the Tesla Powerwall 2 and the highly anticipated Powerwall 3, shedding light on their specifications, features, and potential advantages for homeowners.

Tesla Powerwall 2: Tried, Tested & Trusted

The Powerwall 2 is a reliable home energy storage solution trusted by thousands of Australians.

Boasting a robust 13.5kWh capacity, it delivers a continuous output of 5kW (peaking at 7kW) and features a seamless backup transition for uninterrupted power supply during outages. 

Scalable up to 10 units, the Powerwall 2 provides a customizable solution to meet various energy needs.

Tesla Powerwall 3: What's New?

While the Powerwall 3 has yet to be released in Australia, its anticipated improvements are noteworthy.

With a significant increase in continuous output to 11.5kW and an enhanced LRA motor start of 185A, the Powerwall 3 promises the same limit pushing performance that Tesla is known for. 

Maintaining the seamless backup transition feature, it offers scalability up to 4 units, making it a versatile and powerful energy storage solution.

But What Does That Mean For You?

When determining the most suitable Tesla Powerwall for your needs, the decision often hinges on whether you require the higher continuous kW output offered by the Powerwall 3.

The average daily energy consumption for a typical Australian household stands at around 18 kW, and it’s crucial to consider that this usage is spread throughout the entire day. 

Most of this demand is effectively managed by your solar system during daylight hours, making the battery essential primarily for periods when your solar system isn’t generating power and to safeguard your home during blackouts.

Understanding your specific energy consumption patterns will guide you in making an informed choice between the Powerwall 2 and the upcoming Powerwall 3.

If your energy needs align with the capabilities of the Powerwall 3, it could be the ideal solution to meet the higher continuous output requirements.

However, for many homeowners, the reliable and more scalable Powerwall 2 may continue to be a cost-effective and efficient choice, given most households won’t need more than 5Kw of continuous output, especially when coupled with a well-designed solar system.
