MOS Reference: Horizontal-axis small wind turbine generator for residential and off-grid power supplementation. Three aerodynamic fiberglass blades with optimized airfoil profile capture wind energy across a wide speed range. Permanent magnet three-phase alternator with built-in rectifier outputs DC for battery charging. Automatic tail vane yaw tracking keeps rotor facing into the wind. Overspeed protection via electromagnetic braking and furling. Complements solar panels for 24-hour renewable energy generation.
