Tumo-Int 1000W 3Blades Wind Turbine Generator Kit with Wind Boosting Controller (24V) 1000 Watts rated wind turbine generator kit. Requires low energy to start up and generates great energy. No noise. The product package includes generators, blades, controllers, screws , bolts and nose cone. Permanent magnetic triple phase AC generator. Easy installation and 1 year warranty on maintenance. Model: 1000W 3 Blades Rated Power: 1000W Maximum Power: 1050W Number of blades: 3 Start-up wind speed: 2.5m/s Rated wind speed: 12.5m/s Survival wind speed: 40m/s Low wind speed wind turbine could effectively utilize wind energy from low wind speed region,it&#039;s recommended to use low wind speed model in no hurricane areas with annual wind speed of less than 3.5m/s. Installation on site is simple, mainly including mounting blades on the hub, securing the hub to the turbine body, installing the nosecone on the blade hub and mounting wind turbine on the pole. For details, please refer to the instruction manual. The safety and operation of wind turbine is closely related with matching components, correct pole installation, correct system cable connection, these three factors we could control and we have to do them well. However, wind turbines are installed outdoors, it is also close with natural environment situations, in case of force majeure factors, such as storm, earthquake, or attacked by hailstone, dust, wind turbines may be damaged. Greater energy production yield Low start up wind speed Maintenance free, easy installation Little vibration, noiseless Permanent magnetic triple phase AC generator The MPPT controller detects the solar panel&#039;s generated voltage in real time and tracks the highest voltage and current value (VI), allowing the system to charge the battery with maximum power output. No environmental pollution.
