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 (not for domestic use).
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. Included 7 x 70mm U-bolts (BZP) for side mounting to 50mm or 60mm OD pole
Stainless steel blades, proven Savonius rotor design and build quality enables it to survive winds up to 35m/s (80mph)
With only one moving set of parts and no brushes to wear out
Small Compact size
Easy to install in places where space is a premium
At only 13.5Kg the LE-v150 Extreme wind turbine can be installed with ease
Designed for sub-zero temperatures
Low temperature bearings and polycarbonate materials ideal for temperatures at -40degC
Designed for corrosive marine environment
The LE-v150 Extreme wind turbine 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 24W at 8m/s (17.8mph) with a peak output of 200W 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!
Build quality & durability
The LE-v150 Extreme wind turbine is manufactured from high quality stainless steel which has been laser processed, CNC machined, hard anodized and powder coated to ensure that the wind turbine will withstand harsh environments.
With only 1 moving part, there is little to go wrong and no brushes or slip-rings to wear out and need replacing. The sealed bearings are fully lubricated, so no greasing or maintenance is required. All of the fixings are manufactured from A4 stainless steel.
Unlike any other small wind turbine you will find, the LE-v150 Extreme′s rotor design will limit its RPM automatically. If anything comes into
contact with the rotating blades, it will be pushed away from the rotor rather than being caught by the spinning and causing damage. These safety features make the wind turbine ideal for installation in places where space might be an issue, and where people are nearby!
Protecting your batteries from over-charging
To protect the batteries from over-charging, a charge controller configured to 'diversion' mode is connected to your battery bank. It operates as an 'overflow' for the battery bank – bleeding excess energy to a dump load when the batteries are full. This means that the turbine is always running – and not being switched on and off as is the case with other charge control methods. Ask us for advice on whether the DL-300 or Tristar 45A charge controller is best for your application.
To protect the batteries from over-charging we recommend you purchase this item as a kit:
