Product Information

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.

  • Silent operation – absolutely no noise as the turbine operates
  • Small compact size – easy to install in places where space is a premium
  • Lightweight – at only 9kg, the LE-v50 wind turbine can be installed with ease
  • Safe – the rotating blades cannot cause injury
  • Reliable – with only one moving set of parts and no brushes to wear out
  • Rugged – LE-v50 Extreme is designed & proven to survive 80mph winds
  • Easy mounting - Extruded aluminium spine and ruggedised brackets for mounting on 50mm OD pole

For locations where wind gusts can reach 27m/s (60mph) or temperatures drop down to -40degC, the LE-v50 Extreme turbine is the wind turbine of choice (see photo in gallery). It features enhancements that reduce the stress and fatigue on the blades during prolonged periods of storm force winds. Features include polycarbonate cowlings, blade load spreader plates, an upper baffle plate to prevent damage to the upper cowling and the turbine is painted black to reduce the build-up of rime ice.

Indestructible build quality & durability

The LE-v50 wind turbine is manufactured from high quality aluminium alloys and stainless steel which has been laser processed, CNC machined, hard anodized and powder coated to ensure that the turbine will withstand the harsh effects of the extreme environments that it was originally designed for. With only 1 moving part, there is little to go wrong and no brushes or slip-rings to wear out and need replacing. The bearings are sealed for life and fully lubricated, so no greasing or maintenance is required. All of the fixings are manufactured from A4 stainless steel which are able to withstand the most corrosive of environments.

The LE-v50 is precision engineered in the UK with only one moving part so little maintenance is required during the turbine’s long operating life.

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!
