The Leading Edge LE-300 wind turbine, a quiet and compact horizontal axis turbine with a rotor diameter of 1m, is considered to be the most rugged  & reliable small wind turbine in its class.

Available in 12V, 24V and 48V for battery charging applications - all at an affordable price!

There are two versions to choose from: the LE-300 for off-grid home and industrial applications on land; and the LE-300 Marine wind turbine, fully optimised for marine conditions, each is available as a kit including charge controller and run/stop switch. 

Manufactured in the UK, the LE-300 wind turbine’s excellent power production stems from an exceptionally low start-up wind speed and superb high wind speed output.  The LE-300 wind turbine is easy to integrate with solar panels to create off-grid power systems that require modest amounts of energy.

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.
