Product overview This 4000W wind generator is designed to begin producing electricity at low wind speeds. Its compact spiral blade design and optimized aerodynamics increase the wind energy utilization coefficient, supporting higher annual power output in areas with light winds. Key benefits Low cut in wind speed: Generates electricity from 1.5 to 2 m/s wind, so it can produce power in lowwind locations where conventional turbines remain idle. Improved energy yield: Spiral blades and refined aerodynamics boost conversion efficiency, increasing yearly generation without changing installation footprint. Ready for 12V systems: Designed for compatibility with 12V battery banks and 12V power systems, simplifying integration with common off grid setups and DC appliances. Compact and practical: Blade and rotor geometry focus on efficient performance while keeping size and visual impact modest for residential and mobile applications. Important attributes Rated power: 4000W. Electrical compatibility: 12V output suitable for standard 12V batteries, charge controllers, and inverters designed for 12V input. Aerodynamic design: Compact spiral blade profile with optimized flow characteristics to raise utilization coefficient and conversion efficiency. Performance focus: Low wind start threshold and design tuned to maximize real world annual output in low to moderate wind conditions. How this product solves problems Keeps systems producing in light wind: Lower start speed lets you harvest energy when other turbines do not generate, reducing reliance on supplemental power sources. Increases usable power over time: Higher conversion efficiency translates to more kilowatt hours per year from the same site and wind regime. Simplifies integration with existing DC setups: Native 12V compatibility avoids complex voltage conversion for many common off grid systems. Practical applications and scenarios Off grid home or cabin: Charge a 12V battery bank to power lighting, communications equipment, and DC loads during variable wind conditions. Recreational vehicle or caravan: Provide supplemental battery charging on the road or at campsites without shore power. Outdoor lighting and remote installations: Power lighting, sensors, or small electronics at farms, parks, and remote work sites where wind speeds are often low. What to consider for installation Match to battery and controller: Use an appropriate 12V charge controller and battery bank sized for the expected output and load profile. Site assessment: Even with low cut in speed, placing the unit in a location with unobstructed wind will improve output and reliability. System components: Combine with suitable inverters, fuses, and mounting hardware rated for the 4000W capability and local conditions. Technical summary Output rating: 4000W. System voltage: 12V. Blade design: Compact spiral blades with optimized aerodynamics for utilization coefficient. Operational wind speed: Starts generating from 1.5 to 2 m/s for improved performance in lowwind environments. This unit is intended for users seeking a dependable 12V compatible wind generator with a low cut in wind speed and a design emphasis on improved conversion efficiency in low to moderate wind conditions.
