S-343 5kW Wind Turbine

Green Energy that works

Cornerstones of Endurance Design

• 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 S-343 has a 6.4m (20.9 ft) 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.
    • 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 components for durability and easy support in the future.
    • Five Year Warranty
      Endurance offers one of the best warranties in the wind industry, covering all defective components and labor for five years.

• Safe Operation

  • When the turbine control system detects any fault, such as high wind or a grid power loss, 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 wind speed and event history. Turbine controls and data are remotely available using the Endurance Remote Interface software.

• 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.
