Tesla Powerwall 3 vs Tesla Powerwall 2

Last week, Tesla released Powerwall 3 to the Australian market for purchase. How does it compare to the tried, tested, and beloved Tesla Powerwall 2? What are the key differences? And, most importantly, which one should you buy?

Powerwall 2 and Powerwall 3 Spec Overview

New Features Seen in Powerwall 3

The biggest difference between the Powerwall 2 and Powerwall 3 is Powerwall 3's in-built solar inverter. The integrated solar inverter means two things: 

• You don't have to pay for or install a third-party solar inverter, and
• It captures a greater yield of solar energy compared to standard setups. 

It also simplifies retrofitting for existing solar energy systems. In the past, installing home batteries required a hybrid solar inverter, such as a Fronius Gen24+ or a SolarEdge Home Hub.

Without a hybrid inverter, adding batteries was costly and complicated, as the old inverter had to be replaced with a hybrid model before battery installation.

Powerwall 3 eliminates this hurdle by featuring an integrated solar inverter. Now, you can easily upgrade to a hybrid solar energy system with battery storage by replacing your old inverter with Powerwall 3. 

Continuous power output has also been improved in Powerwall 3. Powerwall 2 is capable of delivering 5kW continuous power per unit. In comparison, Powerwall 3 can deliver up to 10kW per unit, depending on local conditions. This is a big win, especially if your property has high energy demands. This essentially means that with Powerwall 3, you can power more appliances and devices simultaneously.

Other than these key differences, Powerwall 2 and Powerwall 3 are capable of achieving very similar results and both offer excellent solutions for storing excess solar energy and backing up properties.

Tesla Powerwall 2

The introduction of Powerwall 3 means that Powerwall 2 will eventually cease production. A Tesla spokesperson recently stated, "Powerwall 3 will become Tesla's home storage solution", effectively implying that Powerwall 3 will replace Powerwall 2.

Unfortunately, Powerwall 3 is incompatible with Powerwall 2 systems.

Powerwall 3 will become Tesla's home storage solution.

If you have Powerwall 2 installed at your property, we strongly encourage you to consider your future energy needs.

If you anticipate an increase in energy consumption, this may be your last chance to install additional Powerwall 2 units to future-proof your home and scale with future needs.

Our Thoughts

Powerwall 3 presents an excellent battery offering for the Australian market, and we are eager to see them installed in our customers' homes and businesses. 

If you don't have solar batteries already installed, Powerwall 3 is a great choice.

If you have a Tesla Powerwall 2 already, don't feel like you're missing out on too much - Powerwall 2 remains a premium solar battery and will continue to benefit your property. Our only recommendation is to consider adding more units to future-proof against energy consumption increases; Powerwall 2 is unlikely to be scalable in future if the unit is discontinued and Powerwall 3 remains incompatible.
