The Leading Edge LE-v150 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).
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 draws on our heritage of designing rugged vertical axis wind turbine chargers for powering industrial and research equipment in harsh environments.
The LE-v150 is available as a 12V, 24V and 48V DC wind turbine. Included 4 x 70mm U-bolts (BZP) for side mounting to 50mm or 60mm OD pole.
It can be found all over the world powering small electronic systems in remote places where there is no other power source, and is a great companion to solar PV in ‘off-grid’ renewable energy systems powering communications equipment, meteorology or telemetry instrumentation.
However, the LE-v150 also lends itself perfectly for leisure activities in the Marine sector. The LE-v150 wind turbine provides a strong marine battery charger and is perfect for providing charge into valuable batteries whilst owners are away.
Absolutely no noise as the turbine operates
This vertical axis wind turbine is easy to install in places where space is a premium
At only 13Kg the LE-v150 wind turbine can be installed with ease
The rotating blades cannot cause injury
With only one moving set of parts and no brushes to wear out
LE-v150 is designed to survive winds up to 27m/s (60mph)
Extruded aluminium spine and ruggedised brackets for mounting on 50mm OD pole
The LE-v150 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!
The LE-v150 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 wind turbine will withstand harsh environments that it was originally designed for. The LE-v150 is precision engineered in the UK. 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 which are able to withstand the most corrosive of environments.
Unlike any other small wind turbine you will find, the LE-v150 can even be allowed to run ‘off-load’ with no connection to the batteries – The LE-v150′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 – providing the perfect marine battery charger on the deck of a sailing boat!
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.
