These wind turbines efficiently harness wind energy 24/7. 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 45 mph wind speed.
Maximum Power Point Tracking (MPPT) Smart Controller 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.

Comments about Nature Power Marine-Grade 400 Watt Wind Turbine:
I tested 2 separate units, wind steady at 20 knots, zero watts in return from the unit. Hooked it up to a drill, full speed on the drill produced 60 watts. Sorry too say, but this unit is a waste of time. Over a 2 week trial, I tried different batteries, different loads and the results where all negative. Called the company and try said to try more units, no thanks. Start up speed was 13 knots, was very quiet.
