About these items:500W High-Efficiency Output: The 500W wind turbine generator ensures excellent wind energy utilization for applications ranging from homes to farms and boats, offering versatility in energy solutions. (NOTE: Tower pole not included!)Optimized Wind Utilization: With a start-up wind speed of 2.5m/s and an operating range of 3-25m/s, this generator performs efficiently in wind-rich areas, particularly where average wind speeds exceed 3 Beaufort scale, enhancing power output in high-wind conditions.Durable and Reliable Performance: The system operates quietly at 55dB with a 12V or 24V three-phase AC permanent magnet synchronous generator, providing an extended lifespan. The MPPT controller optimizes power generation by adjusting current and voltage as needed for diverse electrical circuits.Premium Blade Design: The reinforced fiberglass nylon blades are designed for durability, withstanding temperatures from -40°C to 80°C, and are either 3-bladed or 5-bladed, optimizing power generation efficiency. Blade sizes include a 47-inch rotor for 500W and 59-inch rotor for 800W variants.High-Quality Construction: The turbine body is built with die-cast aluminum, making it waterproof and corrosion-resistant. The tail is adjustable to align with wind direction, enhancing performance, and the dual-bearing design ensures quiet, efficient operation.Key Differences:Rated Power: Available in both 500W and 800W versions for varying energy needs.Number of Blades: 500W units have 3 blades, while the 800W unit features 3 blades for more substantial output.Rated Voltage: 500W units are 12V or 24V, while the 800W model is 12V for optimized output.Rotor Diameter: The 500W units feature a 47-inch rotor, and the 800W model has a 59-inch rotor for increased energy production.Noise Level: The 500W models operate at 55dB, whereas the 800W model operates at a slightly higher 58dB due to increased power output.Dimensions and Weight: 500W models are compact with dimensions of 47 x 47 x 26.7 in and a net weight of 14.3 lbs, while the 800W model is larger at 59 x 59 x 40.6 in and weighs 26.9 lbs.Blades Design: The 500W turbine has 3 blades (either 12V or 24V), while the 800W version uses 3 blades to increase efficiency.Specifications:Rated Power: 500W or 800WRated Voltage: 12V or 24V (500W model) / 12V (800W model)Number of Blades: 3 or 5Wheel Diameter: 47 in / 1.2 m (500W) or 59 in / 1.5 m (800W)Startup Wind Speed: 2.5 m/sRated Wind Speed: 12 m/sNoise Level: 55dB (500W) / 58dB (800W)Controller: IncludedProduct Dimensions: 47 x 47 x 26.7 in / 1200 x 1200 x 680 mm (500W) or 59 x 59 x 40.6 in / 1500 x 1500 x 1030 mm (800W)Net Weight: 14.3 lbs / 6.5 kg (500W) or 26.9 lbs / 12.2 kg (800W)Package Content:500W Model:1 x Wind Turbine Generator3 x Blades1 x Wind Cap1 x Controller1 x Sleeve1 x Pack of Screws800W Model:1 x Wind Turbine Generator3 x Blades1 x Wind Cap1 x Controller1 x Sleeve1 x Pack of Screws500W,12V,3-blade Wind Turbine
