Wind Turbine Generator Kit 400W 12V, 3-Blade, Controller

Wind turbine generator kit delivers reliable 12V power supplementation to keep batteries charging in off-grid and backup setups. This 400W, 3-blade system pairs a low start-up wind speed with a compact rotor for steadier output in variable conditions. A 3-phase AC permanent-magnet generator and intelligent charge controller help regulate voltage/current, while a sealed build supports outdoor installation for cabins, RVs, boats, and remote equipment sites.

• Delivers 400W rated output for 12V battery charging and power supplementation


• Starts generating at 2.5 m/s start-up wind speed for improved low-wind usability


• Includes 3-blade rotor and charge controller to regulate voltage and current


• Reduces vibration with dual bearings for smoother, quieter rotation


• Installs easily with hoop-style mounting design; pairs well with solar panels

Built for practical renewable energy systems, this wind power turbine generator supports battery banks and helps extend runtime where grid power is limited or unavailable. The rotor’s aerodynamic blade profile and robust materials are designed for stable operation, while the controller manages charging to protect your system. Use it for remote households, mobile homes, marine battery charging, weather stations, communication sites, or utility outposts. Confirm tower dimensions and battery capacity compatibility before installation. Grab yours today and start supplementing your power with wind.
