The Leading Edge LE-v50 Extreme vertical axis wind turbine is a compact, silent and lightweight turbine designed for battery-charging of low power electronic devices (not for domestic use).

These include data-loggers, radio and telemetry equipment in some of the world's harshest locations - Antartica, Greenland and Arctic Canada. The vertical axis design is able to work effectively in challenging conditions compared with a horizontal axis turbine, read this article in Energy Engineering magazine. 

The LE-v50 Extreme is available as a 12V, 24V and 48V wind turbine. Included 4 x 70mm U-bolts (BZP) for side mounting to 50mm or 60mm OD pole.

Where wind gusts to 35m/s (80mph) or temperatures drop down to -40degC, the LE-v50 Extreme turbine is the wind turbine of choice. It features enhancements that reduce the stress and fatigue on the blades during prolonged periods of storm force winds.

Features include aluminium blades, polycarbonate cowlings, blade load spreader plates, an upper baffle plate to prevent damage to the upper cowling and the black body to reduce the build-up of rime ice.

Pure performance

The LE-v50 Extreme uses a proven ‘Savonious’ rotor design which gives silent and effective performance. Using the latest solid modelling and Computational Fluid Dynamic simulations, we  have come up with an elegant ‘cross-ventilated’ rotor which provides good power conversion for a vertical axis wind turbine of this size.

This wind turbine will output 10 watts @ 12m/s (26mph) with a peak output of 70 watts according to the power curve if sited correctly - read our siting advisory document.

The rotor is then coupled to our specially designed low inertia, zero ‘cogging’ axial flux permanent magnet alternator. Using Neodymium rare earth magnets, this alternator design has become one of the most field proven and effective alternators that is deployed across the entire range of Leading Edge wind turbines!
