12V Vertical Axis Wind Turbine Generator Kit Product overview This vertical axis wind turbine kit is designed for small off grid power systems and battery charging. The 12V model is matched to 12V battery banks and delivers efficient, quiet performance with durable construction and weatherproof protection. Key benefits Reliable battery charging: A threephase AC permanent magnet generator provides steady output and low torque for efficient battery charging when paired with the included external wind charge controller. Lowstarting wind speed: Compact twoblade spiral rotor and dual bearings reduce startup resistance so the turbine begins generating at lower wind speeds. Quiet, smooth operation: Injectionmolded aluminum alloy blades and balanced rotor design minimize vibration and operational noise. Allweather durability: Iron and aluminum alloy construction with IP67 protection helps the unit withstand outdoor conditions. Flexible deployment: Compact size and multiple flange options make it simple to mount on poles, masts, or small towers. Function and compatibility Rated battery voltage: 12V for this model. Other available voltages are 24V, 48V, and 220V. Select the generator voltage that matches your battery system. Important for 220V option: The 220V generator does not directly output 220V AC. Generated power must be stored in a battery and then converted to 220V AC through a separate inverter. The generator cannot be connected directly to a household power grid. Use with a suitable battery bank and a compatible inverter or charge controller as required by your system setup. Performance and materials Blades: Two spiral blades, injectionmolded from strength aluminum alloy with a sprayplastic finish for durability and aerodynamic efficiency. Generator: Threephase AC permanent magnet generator with low torque design for improved annual energy yield. External wind charge controller included for regulated charging. Bearings: Dualbearing rotor for smoother motion and reduced vibration. Protection: IP67 rating for ingress protection against dust and temporary water immersion. Maximum power: 4000 W. Rated wind speed: 13 m/s. Wheel diameter: 0.4 m (1.31 ft). Color: Blue. Materials: Iron, aluminum alloy, and allcopper internal wiring.

What is included 2 blades 1 generator 1 main shaft and arms Bolts and nuts 1 wind controller Typical applications Off grid boat power: Charge a 12V battery bank to run lights, navigation electronics, and small appliances. Remote cabin or tiny home: Supplement solar panels or a generator to keep a 12V battery bank charged for lighting and DC loads. Field equipment and monitoring stations: Provide a reliable trickle charge to batteries for sensors, communications gear, and lighting. Installation notes and recommendations Choose the 12V model for a 12V battery system. Verify battery and controller compatibility before installation. For AC loads or household voltage, store generated energy in batteries and use a separate inverter sized to your load. The turbine does not directly supply household mains. Confirm pole diameter and flange requirements match the listed dimensions for secure mounting. Observe local regulations and safe installation practices when mounting at height. This 12V vertical axis wind turbine kit offers a compact, durable option for adding windgenerated charging to small battery systems.
