The LE-450 is the most powerful small wind turbine with a 1m rotor, able to provide meaningful power levels at everyday wind speeds of 5-8m/s (11-18mph), yet is tough enough to withstand winds of up to 40mph.

The LE-450 is a quiet, powerful and lightweight 450W wind turbine for battery charging applications. Fully optimised for marine conditions, the LE-450 is ideal for supplementing the power supply on-board a sailboat or yacht and provide energy when solar PV panels are unable to operate effectively – during Winter or overnight.

Manufactured in the UK, the LE-450 wind turbine is extremely easy to integrate with solar panels to create small scale off-grid renewable energy systems for powering security, radio communications, lighting, signage and telemetry applications.

The turbine is available in a kit including charge controller, dump load and run/stop switch.Choose between 12V, 24V or 48V for battery charging applications. Please note the LE-450 is not suitable for locations where the winds regularly gust to over 18m/s (40mph).

Powerful in every day winds

The LE-450 generates the same power output as other small wind turbines with blades up to 1.2m long, making it the most powerful wind turbine for its size. The turbine is designed around a unique low inertia axial flux generator which uses Neodymium rare earth magnetic materials. This alternator has zero ‘cogging’ allowing the turbine to spin in the lightest of breezes and to react quickly to gusts.

Its excellent power production stems from an exceptionally low start-up wind speed and superior transfer of power from the wind in everyday winds of 5-8m/s (11-18mph). This is achieved using 5 blades and by fine tuning the alternator to extract the right amount of torque, at the right RPM.
