Product: 4000W, 48V Small Wind Turbine Generator Color: Green Key specifications: Rated power: 4000W (also available in 4500W) Rated voltage options: 12V, 24V, 48V, 220V Wheel diameter: 73 cm Number of blades: 5 Startup wind speed: 2 m/s Rated wind speed: 11 m/s Safe wind speed: 45 m/s Blade material: reinforced nylon fiber with aerodynamic profile Generator: three phase permanent magnet AC synchronous generator with specially designed stator to reduce torque resistance Generator case: casting aluminum alloy Control system: electromagnet with wind wheel yaw Speed regulation: automatic windward direction adjustment Operating temperature range: 40C to 80C Why this turbine is useful: Starts generating at low wind speeds: begins producing power from about 2 m/s, increasing useful energy capture in lightwind locations. Efficient and stable generation: five blades with an aerodynamic, reinforced design improve the wind power coefficient; the permanent magnet three phase generator and optimized stator reduce torque resistance for smoother output. Durable, lowmaintenance construction: aluminum alloy generator housing and reinforced blades provide long service life while keeping weight and vibration low. Easy installation and operation: userfriendly design, automatic yaw and speed regulation, and straightforward mounting hardware make setup and upkeep simple. Performance and compatibility: Suited to small offgrid systems, battery charging arrays, and hybrid energy setups where 12V, 24V, 48V, or 220V systems are used. Compact 73 cm rotor diameter fits rooftop mounts, small towers, or poles while delivering up to 4000W continuous output at rated wind conditions. Wide operating temperature range supports use in varied climates. Included in the package: 1 Wind Turbine Generator 1 Controller 1 Mounting Accessories Bag Practical use scenarios: Offgrid cabin or remote cottage: integrate with a battery bank to provide supplemental power for lighting, refrigeration, and small appliances where grid access is limited. RV, boat, or caravan charging: pair with a 48V battery system to recharge batteries while stationary or during extended stays. Small agricultural or telemetry installations: provide reliable power for pumps, sensors, and monitoring equipment in remote fields or outdoor sites. What sets it apart: Low startup wind speed and optimized blade geometry increase usable energy capture in light to moderate winds. A three phase permanent magnet generator combined with a purposebuilt stator reduces mechanical resistance for more consistent output. Simple automatic yaw control and builtin speed regulation lower the need for manual adjustment and maintenance. Installation notes: Ensure the selected voltage matches your battery or inverter system (12V, 24V, 48V, or 220V). Mount on a suitably rated pole or tower with appropriate grounding and clearance from obstacles to allow yawing. Follow local electrical and structural codes when integrating into existing systems. This turbine is designed to deliver compact, reliable wind power for small to medium offgrid and hybrid applications where lowwind performance and ease of installation matter.
