Heli 4KW On-Grid Wind Turbine Wind Generator

• Universal application for low, middle and high wind
• 3-phase permanent magnets (High efficiency due to strong permanent magnets (NdFeB magnets, 150 ° temperature resistant)
• Aerodynamic design
• Powder coated aluminum housing
• Low noise
• UV-resistant Plastic + 30% glass fibers blades, successfully tested
• Power transmission through slip ring, thereby no twisting of the cable possible
• Durable and low maintenance

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.
