Profile: Senwei Energy Technologies Inc. is a manufacturer of wind turbine generators. We offer 300W to 50KW wind turbine generators, grid tie inverters, small wind turbines/solar hybrid systems, solar power systems, hydraulic towers, and fixed pitch wind systems. Our wind turbine generators feature rotor with diameter of 2.2 m. Exposed parts are made by stainless steel or have passed special long time effective rust-protection treatment, so the outside of those parts dont need maintenance. The generator has adopted high grade SKF bearings and high grade lithium grease. The generator adopt brush less type. The generator could keep working with lower wind velocity-even breeze, just need 2.5-3.0m/s to start-up.
