LE-v50 Extreme Vertical Axis Wind Turbine


Our LE-v50 vertical axis wind turbine is a compact, silent and lightweight turbine designed to trickle charge your batteries or for low power electronic devices such as data-loggers, radio and telemetry equipment. 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 was originally designed to provide power for industrial data monitoring equipment in the most extreme & remote places where there is no other power source.  It can be found supplementing Solar PV panels in ‘off-grid’ renewable energy systems and powering LED street lights and other lighting 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

The Leading Edge LE-v150 Extreme is a rugged, silent and highly reliable vertical axis wind turbine designed to provide power outputs of up to 200 watts for a host of different battery charging applications. These ultra-tough wind turbines are found in some of the harshest locations on earth – Antartica, Greenland and Arctic Canada.

For use in applications where a traditional horizontal axis turbine may be inappropriate and simply couldn’t survive prolonged periods of storm force winds, the LE-v150 Extreme draws on our heritage of designing rugged vertical axis wind turbine chargers for powering industrial and research equipment in harsh environments.

Where wind gusts to 35m/s (80mph) or temperatures drop down to -40degC, the LE-v150 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 stainless steel 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.

The LE-v150 Extreme is available as a 12V, 24V and 48V DC wind turbine.

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 extremely good power conversion for a vertical axis wind turbine of this size.

The rotor is then coupled to our specially designed low inertia, zero ‘cogging’ axial flux permanent magnet alternator to ensure an excellent power curve whilst the turbine starts up in the lightest of winds. 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 Turbines!

Absolute safety

Unlike any other small wind turbine you will find, this turbine can even be allowed to run ‘off-load’ with no connection to the batteries. The LE-v50’s rotor design will limit is RPM automatically. You can even try to put your hand into the spinning rotor, but it will be deflected away before any harm is done! These safety features make the wind turbine ideal for installation in places where space might be an issue, and where people are nearby – perfect as marine wind generators!
