When confirming equipment failure, please contact support promptly with the equipment model and complete problem description.
VAWTs are omnidirectional, meaning they harvest wind from any direction without needing a yaw mechanism. They are quieter, operate efficiently in turbulent urban wind environments, and have a more pleasant aesthetic, making them ideal for rooftops.
The turbine starts generating power at a low startup wind speed of 2.5m/s, and reaches its rated performance at a wind speed of 11m/s.
The system features electromagnet and dump load control, along with automated electric brakes to protect the generator from overcharging and overspeed during storm conditions.
This vertical axis wind turbine is built from high-strength aluminum alloy and premium treated components, designed for a reliable operational lifespan of up to 20 years.
The generator is designed and tested to work smoothly in harsh environments, withstanding temperatures ranging from -40°C up to 80°C.
