This compact and quiet horizontal axis turbine is considered to be the lightest, most powerful and quietest turbine in its class. All at an affordable price.

Leading Edge LE-300 Wind Turbine


Cut In Windspeed: 3m/s (6.7mph)

Available in 12V, 24V or 24V

Available in 12V, 24V and 48V options to suit various battery charging applications.

A marine version of this turbine is also available by request which is fully optimised for marine conditions. This, the standard, version is ideal for off-grid home and industrial applications on land.

The controller is an integrated solution designed to prevent 12 or 24 Volt batteries from overcharging. It incorporates a 300 Watt resistor / heater and controller board in a stout powder coated steel enclosure.

Leading Edge LE-300 Wind Turbine

The LE-300 wind turbine has a heritage that is based around reliability and durability. The LE-300 is precision engineered in the UK with only two moving parts so little maintenance is required during the turbine’s long operating life.

The LE-300 survives winds of up to 27m/s (60mph) by means of a simple passive aerodynamic design that limits turbine RPM and power output at a certain threshold.

Leading Edge LE-300 Wind Turbine

The LE-300 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’ Whispower blades, allow the turbine to generate power at very low wind speeds and deliver a higher output than the competition in high wind speeds.

The turbine has been designed for harsh environments, surviving destructive high winds by means of a passive aerodynamic design that limits turbine RPM and power output at a certain threshold. It is marine quality finished with bearings sealed for life and fully lubricated, so little maintenance is required.

Durable and reliable

Originally designed for industrial applications, withstands storm force winds up to 27m/s, 60mph


The LE-300 wind turbine delivers 85W at wind speeds of 8m/s (18mph)

Lightweight turbine head

Weighs just 6.5Kg, this reduces the loading on the support structure and making installation easy in difficult locations

Appreciated for quietness

Low acoustic emissions from the advanced aerofoil blade design developed specifically for the LE-300 wind generator


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

5 Year warranty

Backed up with excellent customer service from Leading Edge Power in the UK
