Tesla Powerwall 3: Redefining Solar Energy Storage and Industry Insights
Markus Lambert opens the conversation by noting record-breaking solar installation numbers but expresses concerns about a potential market slowdown. Derek McKercher from Perth Solar Warehouse explains that Perth’s highly competitive market is seeing price drops, largely due to manufacturers clearing overstock after a surge in European demand two years ago.
Derek also highlights the challenges facing local businesses, such as reduced subcontractor rates and an increase in smaller, independent competitors. These changes, he explains, have put downward pressure on pricing, making it harder for larger companies to compete.
Key Features of the Tesla Powerwall 3
The much-anticipated Tesla Powerwall 3 launch is a major focus of the podcast. Both Markus and Derek agree it’s a game-changer for energy storage, and they discuss its standout features:
- 20 kW Solar Input: A significant upgrade, the Tesla Powerwall 3 supports larger solar installations, accommodating systems up to 20 kW.
- 10 kW Output Power: This higher output ensures seamless support for household appliances during blackouts.
- Flood-Resistant Design: The aluminium casing provides enhanced protection against extreme weather, including floods.
- Simplified Installation: New tools, such as Tesla’s lifting trolley, make installation easier, even for single-person teams.

Advances in Battery Chemistry and Safety
A key topic of discussion is Tesla’s move to lithium iron phosphate (LFP) battery chemistry in the Tesla Powerwall 3. Derek McKercher from PSW Energy explains how LFP batteries are safer due to their resistance to thermal runaway and their lack of cobalt, addressing both safety and ethical concerns.
“LFP chemistry not only improves safety but also avoids the ethical dilemmas associated with cobalt mining,” Derek notes. Markus Lambert adds that this move aligns with Tesla’s commitment to sustainability, making the Tesla Powerwall 3 an appealing choice for environmentally conscious consumers.
Installation Innovations
The podcast highlights Tesla’s focus on installer-friendly features. The introduction of a motorised lifting trolley for the 130 kg Tesla Powerwall 3 is a standout innovation. Derek explains that this tool significantly reduces strain on installers, enabling faster and safer installations.
“This simplifies installations to the point where even smaller teams can handle larger jobs efficiently,” Markus observes. These advancements, combined with Tesla’s commitment to high-quality materials and user-friendly software, are likely to enhance the product’s appeal among installers and homeowners alike.
Tesla’s Packaging and Environmental Impact
Markus praises Tesla’s new reusable plastic packaging, which not only reduces waste but also rewards installers with a $150 credit for returning the materials. Derek McKercher applauds Tesla’s approach to sustainability, stating,
“They’ve really considered the entire supply chain, from design to packaging, to minimise their environmental impact.”
Challenges in the Solar Industry
While optimistic about Tesla’s innovations, Markus raises concerns about low-cost solar providers exploiting premium brands like Tesla to boost their credibility. These companies often deliver subpar installations, undermining trust in the industry.
Derek responds by highlighting Tesla’s strict certification process and internal auditing system, which ensures that only qualified and trustworthy installers can work with their products. This, he argues, will help safeguard Tesla’s brand reputation and maintain high installation standards.
The Future of Renewable Energy and Electrification
Derek shares insights from his recent visit to China, where he observed cutting-edge solar manufacturing and the rapid adoption of electric vehicles (EVs). He describes Shanghai as a glimpse into the future, with 40–50% EV penetration and advanced solar manufacturing facilities.
Markus predicts that Australia will soon introduce a federal rebate for home batteries, similar to the initial solar rebates. “With growing EV adoption and rising energy costs, home batteries will become essential for balancing the grid,” he argues.
Both agree that integrating solar panels, home batteries, and EVs into a single ecosystem will be the next major step in energy efficiency.
Conclusion: Tesla Powerwall 3 Sets a New Standard
The podcast concludes with Markus and Derek reflecting on the significance of the Tesla Powerwall 3 launch. Its combination of advanced features, simplified installation, and sustainability initiatives make it a standout product in the energy storage market.
For homeowners and installers alike, the Tesla Powerwall 3 represents the future of renewable energy. As Derek aptly puts it, “It’s more than just a battery—it’s a complete solution for modern energy needs.”
