• Durable and low maintenance

Important Notice for Our Valued Customers

While many small wind turbines are widely offered on the market, some are advertised with unrealistic power ratings of 3000–4000 Watts—often at extremely low prices. Please be aware that such claims do not reflect actual performance under real-world wind conditions.

To avoid disappointment, we strongly advise you to carefully review the product specifications and ensure that the system you are considering truly meets your energy needs. Making an informed and responsible choice is essential for investing in a reliable, efficient, and long-lasting wind power solution.

The Heli wind turbine is a wind generator that is ideal for inland locations. Depending on the selection, it is specifically designed for battery charging of 48 volts or on-grid power supply.

The azimuth mount is installed only on our helicopter model; The bearing is designed as a double-race plain bearing and is equipped with grease fittings for re-oil.

The repeller blades and nacelle cover are hand-laminated and painted.
