A wind turbine is a device that converts wind energy into electrical power. The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs.Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid.

TINVOSOLAR took the lead in the mechanical centrifugal variable pitch wind turbine in the field of R&D and manufacture in China, now has production of 2kW, 5kW, 10kW, 20kW, 30kW variable pitch wind turbine, All products stand on our own research and development, have complete independent intellectual property rights, has obtained Chinese Invention patents 8pcs, Utility model patents 16pcs, International PCT patents 3pcs, and has applied patents in The United States and European .
