The Tesla Powerwall 3: Redefining Home Energy Storage

The Tesla Powerwall 3 is a fully integrated energy system designed to work smoothly with your solar panels, home appliances and lifestyle.

Below we break down the key features that make the Powerwall 3 a fantastic option for Australian homeowners:

High Power Output

With a continuous power output of 11.04 kW, the Powerwall 3 can power high-energy appliances such as air conditioners, electric vehicle (EV) chargers, pool pumps and home entertainment systems all at the same time. Its high load start capability can support the initial surge required to start heavy appliances making it a great choice for whole-home backup during power outages. This freedom gives you control over your own power.

Optimised Solar Integration

Unlike the Powerwall 2 and traditional battery systems, the Powerwall 3 now features a built-in hybrid inverter with three Maximum Power Point Trackers (MPPTs) and can manage up to 20 kW of solar. Its design achieves an impressive 97.5% solar-to-home efficiency meaning homeowners are accessing almost all the energy they produce.

Also, the multiple MPPTs gives more flexibility when designing solar array configurations which is ideal for homes with complex roof designs or partial shading. You will be able to capture more solar energy even in less-than-ideal conditions boosting the return on your investment.

Reliable Backup Power

Power outages caused by storms, bushfires or grid failures disrupt your daily life massively. The Powerwall 3’s seamless backup powers your home during unexpected events. You’ll have peace of mind knowing you’re protected during a power outage. The Storm Watch feature adds an extra layer of preparedness by pre-charging the battery before severe weather.

Significant Savings

The Powerwall 3 gives you real-time control over your energy via the Tesla app. From your phone, you can monitor the solar production, battery status and energy consumption. The Storm Watch feature uses weather forecasts to automatically charge the battery to full capacity before severe weather events preparing you for outages which are becoming more common in Australia.

The time-based control feature allows you to charge your PW3 during low-cost periods and discharge during peak rate times. This means more savings in regions with time-of-use tariff plans. Also, the introduction of the 30% federal solar battery rebate can lower the total cost of a Powerwall 3 by about $8500 after incentives, making it a smart financial investment with long-term returns.

Engineered for Australia’s Climate

Australia’s diverse climate needs resilient technology. The Powerwall 3 is flood-resistant up to 70cm and operates in temperatures from -20°C to 58°C. Its Lithium Iron Phosphate (LFP) battery chemistry is safer, more stable, and less prone to degradation than traditional batteries and backed by a 10-year warranty guaranteeing 70% capacity retention. The Powerwall 3 is proven to be built to endure Australia’s toughest conditions.

Environmental Responsibility

The Powerwall 3 reduces your environmental impact which aligns with Australia’s growing commitment to renewable energy. Reducing your reliance on fossil fuels helps to build a more sustainable Australia.

Increased Property Value

A home with a Tesla Powerwall 3 is more attractive to buyers in today’s property market. Its advanced technology, reliability, and ability to reduce costs can increase your property’s value by potentially tens of thousands making it smart investment for homeowners.

Tesla Powerwall 3 Expansion Pack

The Tesla Powerwall 3 Expansion Pack is designed without the built-in inverter which provides homeowners with a cost-effective way to expand your energy storage. It seamlessly integrates with the Powerwall 3 supporting up to three expansions for a total of 54 kWh (13.5kWh per unit). This is perfect for extended backup during outages and maximising solar savings. Now available for pre-order it is under review by the Clean Energy Council and is planned to be approved sometime in Q2 2025.

Limitations – Three-Phase Installations

Although the Tesla Powerwall 3 is a robust and adaptable solution for most Australian homes, it has certain constraints in three-phase properties:

• Single-Phase Backup Only: The Powerwall 3 is designed mainly for single-phase homes and can only support backup power for just one phase in a three-phase home. In the event of a power outage, only the appliances and circuits connected to the supported phase will remain powered. For example, if your air conditioner, EV charger, or other high-energy appliances are on a different phase, they will not work in a power outage unless they are rewired to the backed-up phase.

• Restricted Power Distribution: In three-phase homes, the Powerwall 3’s 11.04 kW output is limited to the single phase it’s connected to. Homes with evenly distributed loads across all three-phase loads such as machinery, HVAC systems or electric vehicles may require extra Powerwall units or alternative systems to achieve whole-home backup. This will significantly increase costs.

Our aim is to be transparent and work closely with you to assess your home’s electrical setup during our free consultation. Our team can recommend customised solutions to address these challenges so you get the most out of your Powerwall.

Is the Tesla Powerwall 3 Right for You?

Deciding on a Tesla Powerwall 3 comes down to your home’s energy needs, budget, and long-term goals. This cutting-edge system offers unmatched performance smoothly pairing with your solar panels and allowing room to grow with expandable storage options. That said, it’s worth taking a close look at your electrical setup to ensure it’s the perfect fit, especially for homes with unique configurations like three-phase systems.
