Key Features Build To Last: Premium aluminum, nylon fiber, and stainless steel are treated with baking paint, which is corrosion-resistant, heat-resistant, not easily deformed or broken, and has a long service life. High Efficiency: The design of 5 blades can achieve relatively high efficiency in wind energy capture, and the 100W high-power motor can achieve fast reading and efficient power generation. Smooth Operation: Its starting wind speed is low (8.2 ft/s) and has an automatic windward adjustment function, which can work smoothly in different wind directions. Safe Use: When the maximum wind speed reaches 114.83ft/s, this product will automatically stop, effectively preventing overload. Vertical design can reduce wind pressure caused by rotation, the IP67 protection level, and the white appearance that can reflect most of the heat energy can provide good protection, allowing the equipment to resist extreme weather environments. Eco-friendly: This product can convert wind energy into electrical energy . 2 Voltages Available: You can choose between 12V and 24V specifications according to your needs. Details 4-Hole Flange Fixation: The four-hole standard DN25 flange is easy to install and can firmly fix the product in the desired position. The humanized flange mounting design makes the installation, maintenance, and overhaul of the equipment more convenient. Controller: It is equipped with wires in three colors: green, black, and red, and has a wiring diagram for easy wiring. Application This product is suitable for energy supply in wind-solar complementary households, ships, pavilions, cabins, RVs, streetlights, etc. Specification  Material: Aluminum, Nylon Fiber, Stainless Steel Process: Baking Paint Color: White Style: Modern Assembly Required: Yes Generator Type: Permanent Magnet Levitation Generator Braking Method: Electromagnetic Wind Direction Adjustment: Automatic Number of Fan Blades: 5 Rated Power: 100W Rated Battery Voltage: 12V/24V Protection Level: IP67 Number of Installation Holes: 4 Max.
