More about the new Tesla Powerwall 3. . .

Solar Inverter is Built Into Powerwall 3
& Barra Solar are the Trusted Installers.

It connects directly to your solar panels, delivering power now and storing energy for later—whether for night use or in a blackout. Tesla Powerwall 3 transforms your home, saving you money while keeping you powered up. It’s the future of home energy and you can PRE-ORDER NOW!

Barra Solar Power are the local leaders in Tesla Powerwall installation, one of the first in the country installing them in fact.  We have been Tesla through and through from day dot, and now we are poised to give you the best results from your Solar and Tesla Products. 

Unmatched American Craftsmanship

The Tesla Powerwall 3 embodies the best of American engineering, known for its precision, durability, and attention to detail. Built in Tesla’s state-of-the-art Megafactories, it is designed to deliver long-lasting performance and reliability.

Built to Last

Manufactured to the highest standards, the Powerwall 3 is a robust energy storage solution you can trust for your home, providing consistent, dependable energy when you need it most.

Proven Quality

By choosing the Tesla Powerwall 3, you’re investing in American-made excellence. With a reputation for reliability and superior craftsmanship, it ensures your energy needs are met without compromise.

The Tesla Powerwall 3 brings several new features and improvements over its predecessors, making it one of the most advanced home energy storage solutions. Here are the key features:
 

1. Integrated Solar Inverter

  • One of the biggest changes in Powerwall 3 is the built-in solar inverter. This integration means that a separate hybrid inverter is no longer needed for string inverter solar systems. The Powerwall 3 can convert the energy produced by solar panels directly into electricity that can be used by the home.

 

2. Capacity and Scalability

  • The Powerwall 3 has a storage capacity of 13.5 kWh per unit.
  • It is expandable, allowing up to four units to be connected for a combined capacity of 54 kWh. Scalability is expected to increase to support up to 216 kWh by early 2025, making it suitable for larger homes or commercial applications.

 

3. Power Output

  • Offers a continuous power output of 11.04 kW. However, in regions like New South Wales, Australia, it is typically programmed to a maximum output of 10 kW to comply with local grid restrictions.

 

4. Advanced Safety with Lithium Iron Phosphate (LFP) Cells

  • The Powerwall 3 uses lithium iron phosphate (LFP) cells, which offer enhanced safety, stability, and durability compared to the nickel manganese cobalt (NMC) cells used in Powerwall 2. LFP cells are less prone to thermal runaway, reducing the risk of overheating and fires.

 

5. Flood-Resistant Design

  • Designed to withstand flooding, the Powerwall 3 can be submerged in water up to 600 millimeters (about 24 inches). This feature makes it highly suitable for regions prone to extreme weather conditions, including mild flooding.

 

6. High Charging and Solar Input Capacity

  • It supports 5 kW of charging power, making it quick to recharge from solar or the grid.
  • It can handle up to 20 kW of solar input, allowing for a larger solar panel array to be integrated with the Powerwall 3 for maximum energy production.

 

7. Three Maximum Power Point Trackers (MPPTs)

  • Equipped with three MPPTs that optimize solar energy production even in cases of shading or when panels are installed at different angles or orientations. This ensures better energy generation efficiency across varied conditions.

 

8. Indoor and Outdoor Installation

  • The Powerwall 3 is designed to operate efficiently across a wide range of temperatures (from -20°C to 50°C), making it suitable for both indoor and outdoor use in various climates.

 

9. Compact and Lightweight

  • Despite its robust capacity and features, the Powerwall 3 has a compact design with dimensions of 1099 mm x 609 mm x 193 mm and weighs 130 kg, making it easy to install in a variety of settings.

 

10. Backup Power Capabilities

  • Like its predecessors, the Powerwall 3 provides backup power during outages, allowing essential home appliances to continue running without interruption.
