use the wind

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

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.
