  • Page 3: Read This First

    Read this first Don’t connect the wind turbine in the wrong polarity Make sure you connect the +ve of the turbine to the +ve of the battery (red to red) and the -ve of the turbine to the -ve of the battery (black to black). Failing to do so will damage the equipment and invalidate your warranty.

  • Page 4: Introduction

    Leading Edge Turbines has spent many years developing the ideas and technology behind your turbine. The LE-450 features an array of innovations and construction techniques as well as heavy- duty engineering to ensure optimum efficiency and a long operating life. All of these features have evolved from the long and successful history of the LE-300 turbine.

  • Page 5: Safety Precautions

     Working with tools of any kind can be dangerous. Your LE-450 turbine requires some basic mechanical assembly with rudimentary hand tools. If you are in any doubt about how to use these tools correctly, please seek advice from a suitably experienced person.

    Package Contents Your LE-450 turbine will arrive containing the components shown below. If any of the items are missing or damaged, please contact your dealer immediately. LE-450 Chassis: Qty 1 Rotor Blade: Qty 5 Hub Plate: Qty 1 17 x M6 Nylock Nuts...

  • Page 8: Mechanical Assembly Procedure

    If the magnet rotor rubs, or no voltage is detected whilst turning the magnet rotor, please contact your dealer immediately. Warning: The magnet rotor within your LE-450 turbine is constructed using neodymium iron boron rare earth magnets. These are extremely powerful magnets and can cause injury if not handled with respect.
  • Page 9 3) Rotor Blade Assembly - Take the five rotor blades and rotor hub plate. Be careful when handling the blades, they may have sharp edges. Use a 10 mm socket & hexagon key and three M6 x 16 mm Cap Heads to attach each blade to the hub plate - see Fig-5. Ensure that the cap head end of the screw is on the inside of the blades (thus allowing the washers and nuts to locate on rotor hub plate side).
  • Page 10 5) Fit the Rotor Blade Assembly - The assembled rotor blades can now be fitted to the LE-450 chassis. This is done by offering the rotor hub plate against the drive shaft protruding from the front of the chassis. M5 x 20 mm Hex Head screws should then be used to fix the rotor hub in position using the six tapped holes in the drive shaft.
  • Page 11 M5 Washers Fig-9: Attach the nose cone 8) Prepare the Turbine Mount - If you have purchased a LE-450 mount bracket or tower from a Leading Edge Turbines’ dealer, then please refer to the separate installation instructions supplied with the product. If you have sourced your own tower / mount bracket, 6.5 mm diameter holes will need to be drilled in order to secure the turbine.
  • Page 12 2.5 mm² 4 mm² 10) Mount the LE-450 Turbine onto the Support Structure - Ensure that the previously installed power transmission cables are not yet connected to any batteries and are ‘shorted’ together. This will prevent the turbine from operating during the installation process.

  • Page 13: Electrical Installation

    This type of system will often expand ‘organically’, but the following guidelines should be followed:  Follow the appropriate electrical code - The electrical wiring of your LE-450 turbine and associated electrical systems must be done in accordance with national and local electrical codes and regulations.
  • Page 14 Tristar diversion controller.  ‘Hybrid’ Systems - The LE-450 turbine can be used in parallel with PV panels. We recommend that the PV panels are wired independently with a separate charge controller specifically designed for use with them and connected in parallel with the battery bank - see Fig-13.

    LE-450 (see Fig 16).  Operation of the LE-450 in High Winds - Every effort has been taken to ensure that the LE- 450 will withstand the forces exerted by strong winds. However the raw power in high winds is immense and the stresses placed upon the turbine are magnified by gusty and turbulent conditions.
  • Page 18 Fig-16: Tethering the rotor blades using the hole on the tail-fin (shown on an LE-300 Turbine) Note: Never allow the turbine to run off-load with no connection to a battery bank or grid-tie inverter. Doing so will allow open circuit voltages to be generated by the turbine. These voltages may be dangerous and may damage the stator coils within the turbine.

  • Page 19: Maintenance

    Carefully remove the yaw mount bracket by unscrewing the four connection screws from the sides of the LE-450 chassis. Inspect the slip rings and wipers for obvious signs of wear. Replace the wipers if required (part numbers available in the Spares section). Reassemble the yaw pivot carefully (do not to pinch any cables).

  • Page 20: Spares

    Spares The following components may need to be replaced during the service life of your LE-450 turbine. Please contact your nearest Leading Edge Turbines’ Dealer, and quote the part numbers listed below. Rotor Blade (set of 5) DP-LETU-145 (X5) Magnet Rotor...

  • Page 21: Warranty

    Warranty Your LE-450 turbine from Leading Edge Turbines (LET) carries a two-year warranty, as supported by a retailer’s receipt. The warranty starts from the date of installation or ninety (90) days after shipment from the LET factory, whichever comes first.

  • Page 22: Disclaimer

    The user of this information and product assumes full responsibility and risk.  The LE-450 turbine is a source of electrical power. It must be installed in accordance with local building and electrical regulations. Consult your local planning (zoning) office for details.

  • Page 24 Introduction Please read this manual and the specific manual for the Tristar Charge Controller before attempting to assemble, install or operate your Tristar Charge Controller. This will assure optimum performance and safety. The Tristar Charge Controller and Dump Load is a 3 party solution designed to prevent 12, 24 or 48V batteries from overcharging.
  • Page 25 Always keep lead-acid batteries the correct way up. Do not allow the acidic electrolyte to spill or come into contact with your skin. Always follow the manufacturer’s safety instructions when handling lead-acid batteries. Please use common sense when installing and operating your turbine and Charge Controller. Electrical Installation Please refer to the overall electrical schematic in the turbine installation for appropriate generic wiring diagrams.

  • Page 40 Universal Run / Stop Switch. This will assure optimum performance and safety. The Universal Run / Stop Switch is designed to allow the user to dynamically brake an LE-450 turbine at will. This is achieved by disconnecting the power output of the turbine from the relevant load and diverting it to a short circuit which then applies the dynamic braking effect on the permanent magnet alternator of the turbine.
  • Page 41 If the unit is to be integrated into an existing panel, a suitable cut-out, as detailed on the wiring diagram will need to be made.

  • Page 43 In this situation, the turbine is free spinning but no voltage will be measureable at the turbine output cables. If an internal fault is present, please contact your dealer or Leading Edge Turbines for further advice. Issue: The rotor hub plate fixings do not correctly grip the rotor hub plate which means that the rotor hub plate can rattle slightly.
  • Page 44 The LE-450 is designed to be slightly tail heavy so that when it is fitted to a yacht that is healing in the wind, the turbine will favour the windward side.
  • Page 45 Common Problems pertaining to low turbine output Issue:  The turbine seems to be operating correctly, but the electrical output appears to be low. There are many reasons why the turbine may be demonstrating outputs that are lower than anticipated. These reasons can stem from turbulence, erroneous measurements through to battery type and condition.

  • Page 46: Appendix 4: Turbine Site Selection

    For areas that are generally flat, the turbine can be installed in any position. Remember that the LE-450 has a low voltage output, so it is important to keep the cable run to the batteries / inverter as short as possible.
