LE-v50 Extreme Vertical Axis wind turbine
ultra-tough for extreme environments
Precision engineered in the UK
Warranted to 35m/s (80mph) winds
Designed for sub-zero temperatures
2 year warranty
The LE-v50 Extreme is available as a 12V, 24V and 48V wind turbine. Included are 4 x 70mm U-bolts (stainless steel) for side mounting to 50mm or 60mm OD pole.
KEY FEATURES
TThe Leading Edge LE-v50 Extreme vertical axis wind turbine is a compact, silent and lightweight turbine designed for battery-charging of low power electronic devices (not for domestic use).
These include data-loggers, radio and telemetry equipment in some of the world's harshest locations - Antarctica, Greenland and Arctic Canada. 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.
Where wind gusts to 35m/s (80mph) or temperatures drop down to -40degC, the LE-v50 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 aluminium 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.

harnessing wind with British innovation
For locations where winds regularly gust to 27m/s (60mph) or temperatures reach -40, the LE-v50 Extreme wind turbine features enhancements that reduce the stress and fatigue on the blades during prolonged periods of storm force winds. It is available in black, has polycarbonate cowlings and low temperature bearings for sub-zero temperatures. Like the standard variant, the LE-v50 Extreme doesn’t require an external charge controller thanks to its unique self-regulating design, making installation straightforward and maintenance minimal. Durable and dependable, the LE-v50 Extreme is perfect for low-power applications; its innovative vertical axis design means it can capture wind from any direction, delivering reliable off-grid power even in turbulent wind conditions.
Pure Performance
The LE-v50 Extreme uses a proven ‘Savonious’ rotor design which gives silent and effective performance. Using the latest solid modelling and Computational Fluid Dynamic simulations, we have designed an elegant ‘cross-ventilated’ rotor which provides good power conversion for a vertical axis wind turbine of this size.
This wind turbine will output 10W @ 12m/s (26mph) with a peak output of 70W 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!
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 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 – perfect as marine wind generators!
minimal maintenance
The LE-v50 Extreme 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.
