2 THE FUTURE OF SUSTAINABLE ENERGY Powerwall is the ultimate battery for your home, which maximises your solar energy consumption and increases your independence from the electricity grid. Made with Tesla s proven battery technology, it enables you to store excess energy generated from solar panels to use at another time, while also offering backup in the event of a power outage. Powerwall enables you to take control of your home s energy needs and helps reduce your monthly electricity costs.

3 USE YOUR SOLAR POWER WHEN YOU NEED IT Photovoltaic solar power is an abundant source of renewable energy that not only costs less than grid power in many parts of South Africa, but adds value to your home as it will continue to generate energy in decades to come. DAILY SOLAR ENERGY CONSUMPTION WITH POWERWALL Typical residential PV systems produce more electricity than the home needs during the day. This excess solar energy gets wasted when you are not able to sell it back to the electricity grid. Powerwall enables you to capture and store your excess solar energy generated during the day and use it even when the sun s not shining meaning you get to consume more of the solar energy you re generating. It also means you ll reduce your dependency on the grid and lower your electricity bills. USING POWERWALL CHARGE DIRECT CONSUMPTION k/w CHARGING POWERWALL EXCESS POWER BACK-UP POWER DURING POWER FAILURES In the event of a power outage, Powerwall powers your home, and allows you to continue to use your solar power. With a capacity of 6.4 kwh, Powerwall can power the essential loads of a typical home, like lights, a security system and key appliances like a TV, Wi-Fi and a refrigerator, for four hours or more.

4 HOW IT WORKS A typical home system includes a Powerwall, solar panels, an inverter, a meter, and in back-up applications, a secondary circuit on your electrical panel. SOLAR PANELS Panels convert sunlight into electricity that charges Powerwall and powers your home during the day. DC POWERWALL Powerwall charges using electricity generated from solar panels, or electricity from the grid. INVERTER The inverter converts direct current electricity from solar panels and Powerwall into the alternating current used by your home s lights, appliances and devices. All Powerwall installations require a compatible inverter. METER A meter is installed to measure the amount of energy fed back into the grid where permitted, and to prevent any feeding back where this is not permitted, or when there is a power outage. ELECTRICAL PANEL Electricity from the inverter is sent to your home s electrical panel. Back-up installations typically require a separate electrical circuit containing the appliances and outlets you wish to back-up. Some back-up installations may require a secondary electrical board. An electrical switch automatically activates the back-up circuit during a power outage. When installed with solar panels, this switch also keeps your solar producing during an outage. AC

5 BEAUTIFULLY FUNCTIONAL Powerwall not only looks sleek but is also waterproof, easy to install and requires no maintenance. It s designed for daily charging and discharging, and the 6.4 kwh energy storage capacity means it will easily power most homes during the evening. Length 1302 mm Width 862 mm Depth 183 mm SAFEST HOME BATTERY ON THE MARKET Thanks to the unique design; Powerwall is a touch-safe system that withstands overcharge and short-circuiting. It also survives mechanical, environmental and electrical stress.

6 ENGINEERED FOR PERFORMANCE With over 100,000+ vehicles sold and more than two billion kilometres driven using Tesla s battery technology, no other company in the world can compare to Tesla s number of successfully deployed battery systems. Powerwall s lithium ion battery inherits Tesla s proven automotive battery technology to power your home safely and economically. THERMAL CONTROL Powerwall is the only home battery with a liquid thermal control, which actively heats and cools the battery to prolong its life, improving safety and allowing indoor and outdoor installation with ambient temperatures from -20 C to 50 C. THE BATTERY WITH A BRAIN Powerwall has intelligent software, which quickly learns and predicts your home s energy pattern, and updates automatically when improvements have been made. 100% USABLE CAPACITY Powerwall s smart charge and discharge system guarantees that you can use the full 6.4kWh capacity, every day and every night. OUR GUARANTEE Unparalleled technology should come with unparalleled warranty. That s why Powerwall comes with a 10-year unlimited cycle warranty.
