    The e300i (1 kW) Wind Turbine

    Available in 12, 24, 48, 110 and 200 Vdc

    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.

    Kit Package includes:

    • e300i (1000 Watt) Turbine
    • e300i Charge Controller (for 12, 24, 48 Vdc)
    • e300i Divert Resistor for Controller (for 12, 24, 48 Vdc)
    • e300i Voltage Limiters
