Kestrel, a Proudly South African product, had developed a reputation across the globe for providing leading edge small wind turbine alternative energy solutions. Kestrel is a subsidiary of Eveready (Pty) Ltd, South Africa’s icon battery manufacturer brand with a proud 70 year old history of providing portable power solutions in South Africa.
The combination of the Kestrel wind turbine technology and Eveready’s ISO certified manufacturing and technical expertise has achieved recognition as Proudly South African Innovator of the Year and Best Exporter. Eveready Kestrel provides small wind turbine solutions in the 600w, 800w, 1kW and 3kW range. Its robust construction and unique engineering makes it the product of choice for telecommunications, off grid, grid connect and water pumping solutions.
The e300i is the next generation of small wind turbine. It is a low starting machine allowing it to generate electricity at relatively low wind speeds. The high performance three blade rotor with pitch control powers a twin axial flux permanent magnet brushless alternator, with good heat management. The e300i maintains its rated output in excess wind speeds, optimising the potential power output and energy yield. More usable power generated, stored and used. The e300i powers telecoms sites around the world.
