Designed and manufactured in the UK specifically for use on boats and yachts, the Leading Edge LE-300 Marine has been fully marinised for a long, trouble-free life.

In addition, the LE-300 Marine has been fitted with stainless steel counterweights to offset the effects of pitching and yawing on the water. Without these counterweights, the turbine would constantly swing back and forth like the pendulum of a clock.

Our British built wind turbines only use high-grade components and, unlike many "cheaper" turbines, we prefer to use stainless steel and aluminium alloys to produce a quality product that will withstand all.

that is thrown at it. Voted as the "Best Value Wind Charger" by Practical Boat Owner, however, the LE-300 Marine won't break the bank.

Nowadays, many of us use both solar and wind power to recharge our battery banks. The LE-300 Marine is designed to be used with a 'diversion load' controller, making it very simple to integrate with a solar charging system and is available in 12V, 24V and 48V versions. Each is available as a kit including charge controller and run/stop switch.

For off-grid home and industrial applications, we also offer the Standard LE-300.

The LE-300 Marine 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.

The 1m rotor diameter of the LE-300 Marine wind turbine 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.
