Product Overview

Low startup speed, maximum output of 400 Watts in a 28mph wind, with marinized protection.

These wind turbines efficiently harness wind energy 24 hours per day, seven days a week. AC output at the wind turbine body ensures that you keep the most power possible over the distance from generator to batteries. High-quality marine-grade coating and construction provide versatility on both land and marine environments.

Maintenance-free design features an industrial strength die-cast aluminum body with carbon fiber composite blades that are engineered for low-noise operation. Maximum power is reached at 28 mph wind speed.

Maximum Power Point Tracking (MPPT) Smart Controller (included) varies voltage to current ratio for the most efficient charging. Automatic regenerative electromagnetic braking system keeps the unit operating within the proper mechanical and electrical limits without manual intervention. Overspeed/Overcrank shutdown prevents damage in high wind conditions.
