The Leading Edge LE-v50 vertical axis wind turbine is a compact, silent and lightweight turbine designed to trickle charge marine batteries or for low power electronic devices such as data-loggers, radio and telemetry equipment (not for domestic use).

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 wind turbine can be found supplementing solar PV panels in ‘off-grid’ renewable energy systems. 

The LE-v50 wind turbine is also a regular sight at marinas providing a trickle charge to valuable batteries whilst the owners are away. This saves money by not having to connect to ‘shore power’ or repair and replace expensive batteries that have been damaged by becoming discharged. It reduces the effects of mains induced electrolysis and corrosion on the boat as well as meaning that owners can go on extended cruises without need to run the engine.

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

Pure performance

The LE-v50 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!
