Low starting wind speed, high wind energy utilization, small size, elegant appearance, and low running vibration;2. The host adopts the latest design hoop connection in 2020, which is convenient, quick and easy to disassemble and save labor;3. The wind turbine blades are precision injection molded with a new process and designed with the latest aerodynamic principles. The wind speed at startup is lower. At the same time, the blades are made of high-strength PA66 and fiber-reinforced nylon. the amount;4. Use rare earth permanent magnet generator with special stator design to effectively reduce the resistance torque of the generator, and at the same time make the wind wheel and generator have a better matching and improve the stability of the unit;5. Added DC output indicator for generator, which is convenient for observing the operation of the fan and has the function of troubleshooting. The lights are eye-catching and beautiful;6.Using the built-in maximum power tracking intelligent microprocessor controller, which effectively adjusts the current and voltage, DC output, waterproof and dustproof, and is convenient for customers to use and install.
