2500W Max maximum wind/solar hybrid output, 2000W rated with wind only
Designed with both reliability and performance in mind, WindMax Wind Turbines feature maintenance free design, high reliability and consistent performance.
A wind turbine is a long term investment. Before you purchase a wind turbine, the first factor to consider is if the energy produced by a wind turbine can pay for itself in 10 years or less. In order to achieve this, the wind turbine must be a high quality, reliable, maintenance free wind turbine with excellent performance.
The second factor to consider is installation and ownership cost. Poor reliability, low quality and high maintenance will greatly increase ownership cost and make the wind turbine impossible to pay for itself.
The third factor is environment and safety. A wind turbine should be safe for high winds, quiet and have no vibrations to make it residential/home friendly.
WindMax wind turbines can meet the above requirements and do much more:
- Designed and built by an experienced wind turbine technology R&D team that are committed to innovation and quality.

- The blades are made of high-strength Nylon-fiberglass materials. They are not the hollow fiberglass blades which are dangerous in high wind and need to be replaced in a couple of years.
Patented, ISO and CE certified WindMax H series is the next generation system built with advanced technology, it is light weight and easy to install. It performs much better and much more reliable than older style wind turbines using furling which is the outdated technology.
The most reliable, most efficient wind turbine with the lowest noise level and Incredible 134 mph (60 m/s) survival speed
With a maximum 2500 watt wind/solar hybrid power output, the H20 performs more consistently and is much more efficient than the side furling wind turbines and has additional solar/wind hybrid output capability.
WINDMAX-H20 system includes generator, hub, 3 blades, Tail, Solar/Wind Hybrid Charge Controller, with Grid-tie/Off-grid Xantrex XW4548 4500w, 48Vdc, 120V/240V AC, 60Hz, split phase Inverter/charger for grid tie or off-grid applications.
Grid-tie wind system with battery backup is the best solution for home and business. You have the unlimited capacity of the grid at your disposal, and you can send your surplus wind energy to the grid. You can still use your system during a utility failure.
A grid-tied wind turbine with battery backup and hybrid wind/solar output is designed to do provide uninterruptible power at lower cost than batteryless grid-tied wind turbine. Grid-tied wind turbine with battery backup is more reliable than grid-tied, batteryless wind turbine system.
Advantages of grid-tied wind turbine with battery backup and hybrid wind/solar output:
1) If both grid-tied solar and wind generator systems deployed, two separate grid-tied inverters are needed for wind and solar. Only one grid tie interactive inverter is needed for grid-tied wind turbine with battery backup and hybrid wind/solar output simultaneously, the reason is that the grid-tied wind turbine with battery backup and hybrid wind/solar output has a hybrid controller and it can control both wind and solar input.
2) Provide Energy Independence for remote off grid sites.
3) Provide Backup power for during outages.
4) Higher reliability than batteryless grid-tied wind turbine, grid-tied wind turbine is relatively new on the market and there are lots of interoperability issues with the grid-tied inverters.
5) There are only a few grid tied inverter choices, grid-tied inverters must be fully tested to function properly in order to achieve higher efficiency and avoid problems.
In summary, if batteryless wind turbine system is configured right, it should be 7% to 10% more efficient than grid-tied wind turbine with battery backup and hybrid wind/solar output, and easier to to install, but during a utility failure, these systems will not provide any electrical backup. Batteryless grid-tied wind turbine is more expensive due to the higher expense of grid-tied inverters if you have both solar/wind systems grid tied. Grid-tied inverter for batteryless wind turbineare is also less reliable due to the limted time on the market.

Hidden cost of old style wind turbines with traditional mechanical furling
Low Efficiency Blades: Even with larger swept area, due to the low production quality and poor aerodynamic design, these old style blades can't capture the power in the wind efficiently. see below table for details.
Poor performance: The furling mechanism is not responsive to the constant changes of wind speed and wind direction. The furling system kicks in either too early or too late to go back to normal operation. This results in poor performance.
High Maintenance cost: The furling components are easy to wear out and break. They need lots of maintenance...therefore they are not a good long term investment.
Heavy Weight: wind turbines with traditional mechanical furling are heavy...therefore they have higher shipping cost, hard to install and maintain.
High Noise Level: Old style wind turbines with traditional mechanical furling is developed without noise control in mind, NOT neighborhood friendly.
Low survival wind speed: 78 mph (35 m/s) survival wind speed can't withstand high winds without damage and turbine needs to be taken down when wind speed exceeds 78 mph, output will diminish during high wind speed events.

Design Features
Advanced over-speed control mechanism vs. old style furling
Problems with old style furling:
Old style furling works well in an ideal, wind tunnel test environment. Realistically, wind speed and wind direction changes frequently and mechanical furling doesn’t have instantaneous response to actual changes of wind status. Especially in bad weather conditions, small wind turbine furling components wear out quickly, therefore, increases maintenance costs and shorten wind turbine service life or causes system failure.
Most of old style furling based wind turbines have three moving parts. It is the moving parts for mechanical over-speed protection that wear out and require a lot of maintenance. Operation of furling based wind turbines would lead to mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other devastating results in the long run.
The rule of thumb for a reliable wind turbine is that the fewer the moving parts, the more reliable the wind turbine is.
Windmax Solution:
Windmax H series adopted Innovative over-speed control so it improves the reliability by abandoning the moving parts for mechanical over-speed protection and minimizing the moving parts to only two.
Innovative over-speed control design of the Windmax H series:
Windmax H series speed limitation abandoned the traditional failure-prone mechanical furling system and solved safety and reliability problems facing most small wind turbines. Advanced speed limitation of Windmax H series is achieved through advanced electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Electromagnetic braking is used in combination with Aerodynamic braking to reduce the rotational speed of the generator.
Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending Windmax H series turbine’s operating speed range into higher speed winds and lower speed winds which are missed by the old style wind turbines.
1. Electromagnetic speed limitation:
Controller will monitor the wind generator rotation through the wind generator output voltage and frequency, and will timely control wind generator rotation by generating reverse reluctance torque if necessary, according to different wind conditions and battery status. Electromagnetic control features quick response, high reliability and therefore ensures the entire control system to be highly reliable.
2. Blade aerodynamic braking:
In high wind speed conditions, patented blades will generate a reverse reluctance torque, so that the blade efficiency falls and the blade rotation speed starts to decline. With the continuing reluctance torque, blade rotation speed is limited to a certain range to prevent damage to the wind turbine blades.
Higher performance at low wind speed
Problem with small wind turbine system on the market today
The most challenging problem facing small wind turbine systems is that power output is very low or close to nothing under low wind condition. The wind speed in most locations don’t stay at rated wind speed all the time, wind turbine actually operates at wind speed lower than rated wind speed at most of the time. In order to have good overall energy output, it is critical for small wind turbine to output as much as power at low wind speed.
WindMax Solution: Strong Neodymium magnet PMA, unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. WindMax system components such as wind generator and blades are designed to output more electricity at low wind speed than other small wind turbines on the market today. WindMax system’s excellent power output under low wind speed results in greater energy production yield and lowest ownership cost.
Wind-solar hybrid power generation wind turbine system
Problem with single source renewable energy system:
1st Generation single source renewable energy systems such as solar systems or wind turbines don’t use renewable energy efficiently. Wind turbines creates less output during the summer, whereas during the winter the solar panels will produce less output.
Windmax Solution:
Our Windmax hybrid solar-wind turbine integrated wind and solar power sources capture the most energy in all conditions. Since solar and wind energy availability differs by locations, seasons and climates, solar and wind energy can be mutually complementary in that solar and wind hybrid systems make full use of wind and solar energy together to generate as much power as possible compared to a single energy source for power generation. A solar & wind hybrid system is more cost-efficient than wind or solar alone.
Easy-to-install, light weight, compact, reliable and maintenance-free wind turbines, designed for both land-based and marine applications.
Problem with old style wind turbine systems:
Most old style wind turbines are heavy weight with unpredictable reliability, hard to install and require lots of maintenance. Due to the fact that most installations are in very remote and inaccessible locations, the old style systems make regular maintenance costly and sometimes impractical.
Windmax Solution:
Windmax H series maintenance free design has a minimum of moving parts with inherent reliability. Our light weight, compact die-casting aluminum alloy generator design makes installation very easy. Rotor blades built with latest advanced thermoplastic engineering and precision injection molding technology is durable and efficient.
