The LE-v50 is a compact, silent and lightweight vertical axis turbine designed to trickle charge your batteries or provide power for low power electronic devices such as data-logging or telemetry equipment.

The LE-v50 was originally designed to provide power for industrial data monitoring equipment in the most extreme & remote places on the planet. Since then, the LEv-50 has become a regular sight at marinas and caravan parks providing a trickle charge to valuable batteries whilst the vehicle owners are away. This saves owners money by not having to connect to ‘shore power’ or repair and replace expensive batteries that have been damaged by becoming discharged. In the yachting world, the LEv-50 also 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 can also be found all over the world powering small electronic systems in remote places where there is no other power source – Such as supplementing Solar PV panels in ‘off-grid’ renewable energy systems and powering LED street lights and other lighting systems.

The LE-v50 is available in 12V, 24V and 48V versions.

• 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 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
• Indestructable – Designed & Proven to survive 120mph Antarctic winds
• LE-v50 Extreme – Designed & Proven to operate in temperatures -40 degrees C and 60 MPH wind speeds.

Indestructible build quality & durability

The LE-v50 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 LEv-50 has a design lift of 20 years +, but due to its modular design and ease of maintenance, the turbine could easily run indefinitely!

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 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, the LE-v50 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 turbine ideal for installation in places where space might be an issue, and where people are nearby – perfect for the deck of a sailing boat!
