• 11.04 kW continuous backup power

• Supports up to 20 kW DC solar input

• 3 independent Maximum Power Point Trackers (MPPTs)

• Fast automatic backup transition during grid outages

• Integrated solar inverter with 97.5% solar-to-grid efficiency

• Optimises solar self-consumption and battery usage

• Compatible with time-of-use electricity tariffs

• Storm Watch feature automatically prepares the battery before severe weather events

• Supports EV charging using excess solar energy

• Modular design allows multiple Powerwall units for increased storage and power

• NRS-097-2-1 Certified and City of Cape Town Approved

All-in-One Energy Storage Solution

Powerwall 3 combines a high-performance battery and hybrid inverter into a single system, simplifying installation while reducing the number of external components required. Its integrated design improves efficiency, lowers installation costs, and provides a streamlined solution for both backup power and solar energy storage.

Reliable Backup Power

With 11.04 kW continuous output, Powerwall 3 can power most household appliances during load shedding or grid outages. It also supports heavy motor starting loads of up to 185 A Locked Rotor Amps (LRA), allowing demanding appliances such as pumps and air conditioners to start reliably.

Maximise Solar Energy

The integrated hybrid inverter captures and stores excess solar energy generated during the day, allowing it to be used during the evening, overnight, or during power outages. With three independent MPPTs, the system can optimise energy production across multiple roof orientations.

Intelligent Energy Management

Powerwall 3 automatically manages energy usage to maximise savings by:

• Storing excess solar energy for later use

• Reducing grid consumption during peak tariff periods

• Automatically preparing for severe weather using Storm Watch

• Optimising battery charging and discharge based on household demand

• Supporting EV charging using excess solar generation

Built for South African Conditions

Engineered for reliable operation in demanding environments, the Powerwall 3 is designed to withstand high humidity, extreme temperatures, and temporary water exposure, making it well suited for South African residential installations.

Applications

Ideal for:

• Residential backup power

• Whole-home energy storage

• Solar self-consumption

• Load shedding protection

• Time-of-use electricity savings
