Vertical axis wind turbine 300 to 400w feature


  • Horizontal axis wind turbines are perfect to use wind electricity for home.
  • HAWT wind turbines use reinforced fiberglass blades for greater wind resistance and higher wind energy utilization.
  • Horizontal axis wind turbine brakes are electromagnetic and automatically adjust to the wind.


  1. The wheel and blades are designed with positioning holes, which can intelligently adjust the direction of the blades according to the wind speed, greatly improving the utilization rate of wind energy.
  2. The blades are made of high-quality reinforced glass fiber reinforced plastic (FRP), with stronger wind resistance and high wind energy utilization coefficient.
  3. Electromagnetic/wind turbine bias side, with maximum power tracking intelligent microprocessor control, effective regulation of current and voltage.
  4. Adopting high temperature resistant Teflon wires, it is not easy to burn the wires when the generator overloads and heats up.

Q1. What is a vertical axis wind turbine and how is it different from a horizontal axis wind turbine?

A VAWT is a wind turbine in which the main rotor axis is arranged vertically.The blades of a HAWT rotate around a horizontal axis, while the blades of a vertical axis wind turbine rotate around a vertical axis. This design has the advantages of simple structure, low manufacturing cost and easy maintenance.

Q2. What is the power output of the 300w/400w VAWT?

A 300w/400w horizontal axis wind turbine typically refers to the power output of a wind turbine, ranging from 300 watts to 400 watts. These turbines are suitable for a variety of applications such as powering remote areas, charging batteries in off-grid systems, or supporting small-scale power needs in residential environments. Their small size and high efficiency make them ideal for decentralized energy generation.

Q3. How to optimize the performance of a 300w/400w vertical axis wind turbine?

To optimize the performance of a 300w/400w VAWT, consider installing it in an area with steady, unobstructed wind flow. Regular maintenance, including inspection and cleaning of the blades, will ensure efficient operation. Additionally, knowing the wind direction in your area and orienting the turbine can significantly increase its power production. Be sure to refer to the manufacturer's guidelines for proper installation and maintenance procedures to maximize the life and efficiency of your vertical axis wind turbine.
