The e300i is the next generation of small wind turbine. It is a low torque machine allowing it to generate electricity at relatively low wind speeds. The high performance three blade rotor drives a dual twin axial flux permanent magnet brushless alternator, for better heat management. The e300i maintains 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.
