Powering Smarter Homes: The Best Solar Batteries in 2025

Featuring Tesla Powerwall 3, Sungrow, BYD & Enphase

As more Australian households turn to solar energy, the next logical step is battery storage. Solar batteries allow you to store excess energy generated during the day and use it later: at night, during blackouts, or when electricity rates are higher. By doing so, you can significantly reduce your electricity bills, improve energy independence, and get the most out of your solar system. However, not all solar batteries are created equal. That’s why we’ve broken down four of the most trusted and innovative brands on the market: Sungrow, Tesla Powerwall 3, BYD, and Enphase.

Tesla Powerwall 3 – Smarter, Sleeker, Stronger

The third generation of Tesla’s industry-leading battery, the Powerwall 3, delivers major upgrades in both design and performance. It combines a powerful 13.5 kWh usable capacity with a built-in solar inverter, making it perfect for both new and retrofit systems.

Why it stands out:

• Seamless integration with Tesla solar and app

• Strong blackout protection and energy resilience

• Sleek, compact, space-saving design

• Industry-leading software and energy forecasting

• Scalable for larger or growing households

If you’re looking for an all-in-one solution with cutting-edge features, the Tesla Powerwall 3 is hard to beat.

Sungrow Battery – Affordable Reliability with High Efficiency
