Bookmark and Share

Wind turbines and accessories that provide the basis for a large number of different battery charging applications, such as: boats; industrial applications; road signage, remote telemetry and decentralised power systems.

Leading Edge LE-300 (Standard) Wind Turbine

The Leading Edge LE-300 wind turbine, efficient, compact, quiet and considered to be the most rugged and reliable horizontal axis wind turbine in its class.

Available in 12V, 24V and 48V options to suit various battery charging applications. (48V option available on request)

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-600 Wind Turbine

Rating: 160 watts @ 8m/s (17.8mph) wind
Peak output: 750 watts @ 18m/s (40mph)
Voltage: 12, 24 or 48 volts DC.
Rotor Diameter: 1.54m
Cut In Windspeed: 3m/s (6.7mph)

Downwind wind turbine capable of producing output of up to 750W.

The LE-600 wind turbine is often used as a wind power addition to an existing off grid power system to compliment Solar PV in order to provide more power in the winter months and cut down on diesel usage. Other applications include remote industrial systems, water pumping systems and lighting and power in remote farm buildings – any application with a moderate power requirement.

Designed for industrial applications in harsh environments. Unique low inertia axial flux generator which utilises Neodymium rare earth magnetic materials to allow the turbine to spin in the lightest of breezes and to react quickly to gusts.

Manufactured from hard anodized and powder coated high quality aluminium alloys and stainless steel with sealed for life bearings, so no greasing or maintenance is required.
