The amount of wind intercepted is very small and contains much less energy. Good performance requires installation in a high wind speed area. This unit may be noisy. Warranty 3 years. Unique 3 blade rotor uses carbon matrix blades which flex to change pitch in the wind.
Body is aluminum casting.
Internal voltage regulator allows direct connection to battery. Can work with a solar charging system. The charge regulator may be disconnected to use an external diversion type charge control to handle solar and wind together for easier voltage adjustment.
