Endurance E-3120 50kw

Large Farms and Industrial Premises

This larger industrial turbine offers great investment potential, performing well in moderate to high wind speed areas. A great advantage with the Endurance is its ability to often pay for itself within the first five year warranty period. For easy planning a minimum distance of 165m to the nearest neighbour is advised, with a 200-300m radius preferred. The reliability of this turbine has been proven over a number of years with banks now being prepared to provide investment towards this wind turbine.

The Endurance E-3120 wind turbine is designed to produce renewable energy efficiently, reliably, safely, and quietly. This turbine is ideal for larger farms, schools, hospitals, and commercial/industrial sites, and will produce 100,000 - 250,000kwh per year in appropriate winds.

Endurance E-3120 Benefits

  • Reduces the environmental footprint of your electrical energy supply.
  • Eligible for renewable energy credits.
  • Promotes community sustainability values.
  • Lowers and stabilizes energy costs.
  • Provides energy independence
  •  

    Anemometer & wind vane
    Measures wind speed and direction to control starting, stopping, and orientation of the turbine to maximize power production.

    Lightning rod
    Guide lightning to the ground, protecting the turbine.

    Nacelle control cabinet
    Houses the tower-top electronics in a weather-protected environment for maximum reliability. The main turbine control panel is located at base of the tower for easy access.

    Induction generator
    Delivers grid compatible power and eliminates the need for an inverter or other power electronics. This improves efficiency and reliability, and reduces up-front costs.

    Fail-safe disk brake system
    Safely stops the wind turbine using twin brake calipers in situations such as extreme wind or grid failure.

    Gearbox
    Drives the generator at full speed while the rotor turns slowly. The gearbox uses rugged, conventional design for long life and high reliability.

    Access ladder
    Allows easy and safe access to the nacelle for maintenance. Ssafety is a top design priority.

    Yaw damper
    While the turbinis aerodynamically oriented by the wind, the yaw damper smooths the movement to ease tower and rotor loads.

    Pitch control safety system
    Provides backup protection against rotor over speed. If the rotor turns too fast for any reason, the blades are pitched by a spring mechanism to control the speed.

    Fiberglass blade
    Designed to quietly and efficiently produce energy, particularly in light winds.

    Tower
    Attractive monopole towers are available in sizes from 24 meters (80 ft) to 36.5 meters (120 ft) to comply with height restrictions or to reach the best winds at your site.

     

    Production Efficiency

    Most distributed wind customers did not select their site for wind resources, but look to generate power from the wind available to them. Endurance wind turbines are designed specifically for less-than-perfect wind conditions.

      Swept Area
      The blades capture the energy of the wind. the larger the rotor diameter, the more wind energy the turbine captures. The Endurance E-3120 has a 19m (63ft) rotor diameter - one of the largest rotor diameters per rated KW in its class - to capture the most wind energy.

      Motoring
      Motoring starts the blades spinning so the turbine operates in lighter wind conditions than if it relied solely on the wind to start (3 phase models only).

      Generator Type
      The induction generator produces electricity that can be transferred to the power grid without inverters. This provides lower equipment and maintenance costs and increases overall power production.

    Reliability

    All Endurance turbines have been extensively tested to ensure customers receive dependable energy production. They are built with proven commercial component for durability and easy support in the future.

    Safe Operation

    When the turbine control system detects any fault, such as high wind or a grid power los, the dual caliper disc brake system activates, safely stopping the turbine until the condition is cleared.

      Passive Stall Rotor Design
      The fixed-speed rotor aerodynamically stalls the blades as the first layer of protection for the turbine during high winds.

      Control and Remote Interface Software
      Each Endurance wind turbine is operated safely by an onboard computer system with advance control logic. This system also records data including energy production, average power, wind speed and event history. Turbine controls and data are also remotely available from a web browser.

    Quiet Operation

    Quiet operation is essential for a wind turbine in a community environment. Endurance turbines use slowly turning blades and high-quality manufactured components to make them the quietest turbines in their class.

    Clean Aesthetics

    A wind turbine makes a powerful statement about your commitment to the environment and clean energy. Endurance wind turbines have clean lines and make an attractive addition to any landscape.
