Powerwall 3 is Tesla’s newest home battery, following the releases of Powerwall 1 (2015) and Powerwall 2 (2017). With over 850,000 units already installed worldwide, it is rapidly becoming a leading choice for energy storage. Available locally through Rubicon from 4 March.
In South Africa, a single Powerwall 3 unit can power most homes, reducing electricity costs by storing excess solar energy produced during the day for use at night when energy prices are higher. Using self-consumption mode, South African customers can reduce their reliance on the grid by up to 67%*, according to Rubicon.
Additional savings are possible with Time-Based Control, which allows homeowners on time-of-use rate plans to charge their Powerwall during low-price periods and use stored energy when prices are high. “On average, homeowners can save up to R29,351 annually by combining Powerwall 3 with solar energy,” said Rubicon.
Powerwall 3 also offers reliable backup protection. In the event of a power outage, it automatically takes over as your home’s energy source. “With Powerwall 3, you get more power, greater efficiency, and enhanced backup protection.”
Boasting over twice the power of Powerwall 2, Powerwall 3 offers flexibility to power homes of all sizes. In South Africa, the inverter delivers up to 11.04 kW of power, allowing homeowners to save more by powering a wider range of appliances.
The integrated solar inverter makes Powerwall 3 more energy-efficient, reduces the complexity of installations by eliminating the need for extra wall boxes, and negates the need for a third-party inverter.
Designed with an advanced thermal management system based on insights from Tesla’s Model 3, Powerwall 3 operates efficiently in a wide range of temperatures (-20 °C to 50 °C) and is built for both indoor and outdoor installations. It can withstand high humidity and even operate in up to 60 cm of floodwater, providing reliable power in challenging conditions.
Seamlessly integrated into the Tesla ecosystem, Powerwall 3 can be controlled through the Tesla App, making it adaptable to various home energy needs.
*Savings estimates are based on an average South African customer with 6 kW of solar and a Powerwall 3, using typical regional consumption and PV production values (approximately 9,965 kWh and 7,575 kWh, respectively). Actual savings vary depending on location, household energy use, and utility rates, which may change over time.
