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.

These dump loads are designed to be connected to Morningstar Tristar TS-45 or TS-60 diversion controllers to 'bleed-off' surplus power when batteries are fully charged.

500W loads for LE-300 and LE-450 (For 12V, 24V or 48V systems).

1000W loads for LE-600 (For 24V or 48V systems).

The Leading Edge LE-3000 is a 3kW wind turbine bridging the gap between micro and small wind turbines.

The Leading Edge Flight Control Computer performs all wind turbine control functions including control in storm conditions.

The Leading Edge Flight Control Computer (FCC) is used to maximise function and protection of the LE-3000 wind turbine.

Includes:

• Central logic controller
• Turbine sensors
• Braking resistors
• Auxiliary inputs and outputs to enable the unit to operate the wind turbine at its optimum no matter the conditions

The FCC can also be used for secondary functions such as charge control in off-grid applications.

The FCC may be placed near the battery bank meaning the longer section of cabling will be higher voltage 3-phase AC reducing cost by utilising smaller lower cost cables.

This allows the turbine to be electrically isolated from the battery systems whilst also bringing the turbine to a near stop by placing a short circuit across the turbine output by putting the alternator into ‘dynamic braking’ mode. Supplied in a pre-assembled, compact IP65 enclosure making it easy to wire-in and mount.
