LE-300 Wind Turbine

From Leading Edge Turbines, the LE-300 wind turbine is considered to be the lightest, most powerful and quietest wind turbine in its class. All at an affordable price!

The LE-300 is a quiet, powerful yet lightweight 300W wind turbine for battery charging & grid connected applications. Fully optimised for marine conditions, the LE-300 wind turbine is also used extensively in a variety of industrial applications, such as powering communication and remote monitoring stations, and in very extreme environments such as Antarctica.

Manufactured in the UK, the LE-300 wind turbine has a proven track record in applications as diverse as powering an Antarctic research station, charging batteries on sailboats and industrial applications such as road signage.  Its excellent power production stems from an exceptionally low start-up wind speed and superb high wind speed output.  Designed to withstand the most extreme wind conditions and environments, the LE-300 wind turbine is also extremely easy to integrate with solar panels for hybrid systems and can be left running through the strongest winds.

Available in 12V, 24V and 48V for battery charging applications, this wind generator can also be grid connected.

  • Excellent value wind charger  – Lowest cost per watt means more power for your buck (see review in Practical Boat Owner magazine)
  • Powerful – The LE-300 wind turbine can deliver outputs in excess of 300W
  • Lightweight turbine head – Reducing the loading on the support structure and making it easier to install on high masts in difficult locations
  • WhispowerTM blades – Low acoustic emissions from the advanced aerofoil blade design developed specifically for the LE-300 wind generator
  • Fully marinised – Aluminium alloy and stainless steel components are protected from the elements with aerospace grade coatings and anodising
  • Easy installation - Fit the blades & nose cone and make the electrical connections. All explained in an excellent user manual with detailed written explanations and diagrams
  • Durable and reliable – Originally designed for industrial applications, durability and reliability is the corner stone of the LE-300 architecture
  • 5 Year warranty – Backed up with excellent customer service from Leading Edge Turbines in the UK

Efficient design from Years of experience in the Field

The LE-300 wind turbine is designed around a unique low inertia axial flux generator which utilises Neodymium rare earth magnetic materials. This alternator has zero ‘cogging’, which, together with its highly efficient and low ‘TSR’ WhispowerTM blades, allow the turbine to spin in the lightest of breezes and to react quickly to gusts.

Small & lightweight

The LE-300 wind turbine has a uniquely designed aluminium alloy chassis that not only gives an overall turbine weight of just 6kg, but ensures responsive reaction to gusty winds.  This reduces the overall size and weight of the turbine and keeps the space envelope small enabling the turbine to be installed on yachts with ease.  The wind generator is fitted with integrated yaw slip-rings that allow the turbine to swivel 360 degrees continuously in order to follow the changing direction of the wind.

Rugged & reliable

As the LE-300 wind turbine has been designed for industrial applications in harsh environments, it has a heritage that is based around reliability and durability.  The wind turbine is designed and manufactured to be as rugged as possible giving a predicted design life of 20 years – With little maintenance required during that period! The LE-300 survives destructive high winds by means of a simple passive aerodynamic design that limits turbine RPM and power output at a certain threshold.

The LE-300 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. The various fixings are manufactured from A4 stainless steel that can survive the harshest of environments. The bearings are sealed for life and fully lubricated, so no greasing or maintenance is required.
