Primus Wind Power Air 40 KWh Wind Turbine Generator 160W / 12 V 24V 48V W/ Control Panel


Product Description

Primus Wind Power's Air wind turbines are the #1 selling small wind turbine generator line in the world! The Primus Air 40 watt wind turbine is the premier wind turbine for off-grid living, boating, RV'ing, outdoor lighting, water pumping, and other low energy demand battery charging applications. Very similar to the Primus Air 30 turbine, the Air 40 offers 10 more KWh and quieter blade rotations. Much like the Air 30, the Air 40 is a great pair for any solar array. 

Using a high-tech micro-processed controller, the Air 40 operates efficiently across a wide range of wind speeds and fluctuations. The blades are aerodynamically designed to operate more silently at most wind speeds. The design is lightweight and a breeze to install or combine with solar panels.

The Primus Air 40 Wind Turbine Generator is manufactured in the U.S.A. and backed by an industry-leading 5-year warranty. High-quality materials help ensure this DIY installation remains durable, even in extreme winds up to 110 mph.
