Why we recommend Tesla Batteries

Tesla is well known for innovation, and their battery packs use the latest lithium-ion battery technology to offer reliable performance and excellent round-trip efficiency. 

The company regularly invests in research and development to improve its batteries. Therefore even though we had the Powerwall 2 for several years in Australia, it is a constantly evolving and improving product. 

We recommend Tesla batteries due to their cutting-edge technology, high energy density, durability, scalability, smart energy management features, integration capabilities, and excellent local commitment to sustainability. These factors position Tesla as a leader in the energy storage industry, offering reliable and advanced solutions for a greener and more resilient energy future.


We all must thank Elon Musk and Tesla for turbocharging the battery storage market in Australia. Tesla batteries are now in their 2nd generation with the Powerwall, and nothing comes close when it comes to brand reputation and visual appeal.

Yes, Tesla batteries are a little more than some upcoming brands, but not much comes close to an AC solution that we know works as well as Tesla.


In 2015 the original Powerwall 1 was launched, with its visually stunning design and a 6.4kWh capacity. At the time, like so many Elon Musk announcements, it attracted comprehensive media coverage following the entrepreneur’s successful EV development.

The home storage battery was primarily marketed as a solution for energy backup during power outages. Then in October 2016, the 2nd generation Powerwall 2.0 was born, which has seen several improvements but is still going strong.

This battery saw a more than doubled energy storage capacity to 13.5 kWh. It consisted of a separate gateway box, an integrated inverter, a simple installation, a great monitor app and a great look.

In 2020, Tesla introduced the Powerwall 2+ and the Powerwall 2 Gateway, which provided enhanced energy monitoring, higher battery control, and more grid connectivity features.


Lithium-ion battery technology

Tesla’s Powerwall is powered by lithium-ion battery technology. This technology offers a high energy density, long cycle life, and fast charge/discharge capabilities. Although the specific type of lithium-ion chemistry employed in Tesla’s batteries is not publicly disclosed. They previously had different suppliers, from Panasonic to LG Chem; the battery chemistry is likely a combination of lithium, nickel, cobalt, and aluminium.

Evolving technology

Tesla’s storage batteries’ capacity and power ratings have evolved over time. Right now, in Australia and NZ, the Powerwall 2 boasts a storage capacity of 13.5 kWh and a power output of 5 kW continuous and 7 kW peak. Larger units are in the pipeline.

Llarge-scale battery solutions

Tesla also offers large-scale battery solutions for commercial applications and has installed some of these in Australia, namely the Hornsdale Power Reserve. This 150 MW storage system is grid connected to assist in the grid stability of South Australia and has been working well since 2017.

Backup power during blackouts

Tesla’s Powerwall 2 supports backup power during blackouts making sure one’s home continues to have basic power for the fridge, lights and other essentials. The technology offers load shifting, which can reduce electricity bills further. By charging the battery during off-peak hours from the grid when electricity rates are lower and discharging it during peak demand periods, users can effectively shift their energy usage and avoid higher tariffs.


Tesla runs several Gigafactories worldwide, which are major production facilities for their storage batteries, among other products. The US production facility in Nevada was Tesla’s original manufacturing hub. It makes battery cells in an automated production line and then converts them into full battery packs in one factory. The facility uses renewable energy in the production process.

Other manufacturing plants in Shanghai, China, produce batteries and the Tesla Model 3 car. A new factory is being built in Berlin, Germany, to supply the European market. Tesla’s Gigafactories offer vertically integrated facilities that combine research, development, and production under one roof. Their large economy of scale allows cost reductions in production processes.


Tesla, Inc., the electric vehicle and energy storage company founded by Elon Musk, owns and operates its Gigafactories, including those dedicated to producing Tesla storage batteries. The ownership of Tesla’s Gigafactories, including the storage battery production facilities, lies with Tesla, Inc. The ownership structure of Tesla, Inc. consists of various shareholders who hold ownership stakes in the company, with Elon Musk, the CEO being the largest, holding approx. 20% of the company.

Global Distribution

Tesla has established a global distribution network to facilitate the distribution and sale of its storage batteries, including the Powerwall  2. It developed the Tesla Stores concept, where customers can relax, explore the products, get questions answered, and buy Tesla products.

Tesla also offers overseas an online option for customers to purchase storage batteries directly through its official website. The online sales platform allows customers to browse product information, configure their storage system, and place orders.

In Australia, Tesla batteries can be purchased by end customers from many installers, who then purchase the battery from Tesla’s distribution network from companies such as Solar Juice.

Has had supply issues in the past and cost fluctuations due to its popularity

The Tesla Powerwall has carried the torch for early adopters to embrace renewable energy and gain greater energy independence. Tesla’s commitment to positive marketing, innovation and continuous product improvement has positioned the Powerwall as one of the leading residential energy storage solutions.

Recommending Tesla batteries is justified due to their cutting-edge technology, high energy density, durability, scalability, smart energy management features, integration capabilities, and commitment to sustainability. These factors position Tesla as a leader in the energy storage industry, offering reliable storage solutions via the Powerwall 2 and a desirable addition to most solar systems.

As the Powerwall 2 has been in the Australian market for ½ a decade without issues, one can trust the Tesla product to deliver energy storage without a hitch.
