E-3120 50kW Wind Turbine
Green Energy that works
The Endurance E-3120 50kW 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 – 250,000 kWh per year in appropriate winds.
- Reduces the environmental footprint of your electrical energy supply
- Eligible for renewable energy credits
- Promotes community sustainability values
- Provides an additional revenue stream with the Feed-In-Tariff Program
Cornerstones of Endurance Design
-
Production Efficiency
Endurance’s E-Series 50kW product highlights include:
- Large 290m2 swept area (19.2m DIA) – captures more energy
- Induction generator, no invertors - we have zero electrical conversion loss
- High kWh production and lowest cost per kWh in its class
- Peak capacity output in wind speeds between 5.5 and 7.5 m/s
- Endurance’s X-Series 225kW product highlights include:
- Delivers optimal size for distributed wind generation power and performance
- Induction generator, no invertors - we have zero electrical conversion loss
- 29.1m diameter rotor
- 30m, 40m tower heights
- Grid connection capability: 50Hz 400V; 60Hz-480V
-
Reliability
- Engineering excellence and exhaustive testing are the cornerstones of our wind turbine design, production and deployment process. Throughout initial design and subsequent revisions, all of our models are manufactured to ensure our customers can count on their turbines over a 20-year lifespan. We also offer a standard 5-year warranty on parts and labor for all Endurance products.
-
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 energy production, average power, wind speed and event history. Turbine controls and data are also remotely available from a web browser.
- Passive Stall Rotor Design
- 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.
-
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.
