Product overview This 3000W, 12V hybrid charge controller combines wind turbine MPPT boost control and solar PWM charging with MOS tube series switching. It is designed to manage energy from wind and solar inputs, provide continuous efficient charging under low wind conditions, and handle excess power with a stepless discharge function and support for an external dumpload resistor. Key benefits Efficient charging from wind: The wind turbine charging section uses booster MPPT technology to capture energy continuously and efficiently, including at low wind speeds. This increases usable output compared to fixedvoltage control. Reliable solar charging: Solar input is managed with PWM technology implemented through a MOS tube in series to improve conversion rates and reduce losses during charging cycles. Intelligent load management: Stepless discharge control plus compatibility with an external dumpload resistor allows smooth handling of surplus energy and prevents abrupt cycling or wasted power. Sized for substantial systems: 3000W capacity with 12V system compatibility supports moderate offgrid installations and larger battery banks at 12V nominal voltage. Practical and durable design: Built to integrate with common 12V setups and to operate as a combined wind and solar charge solution for hybrid systems. Key functions and specifications Size: 3000W nominal capacity System voltage: 12V Wind turbine charging: booster MPPT technology for continuous and efficient energy capture, effective at low wind speeds Solar panel charging: PWM control implemented through MOS tube in series to enhance conversion efficiency Discharge control: stepless discharge function with support for an external dumpload resistor to manage excess generation Intended use: hybrid charge control for combined wind and solar inputs in 12V systems Compatibility and performance notes Designed for 12V battery systems and battery banks Suitable for integration with a variety of wind turbine and solar panel configurations that match the stated electrical parameters Performance emphasis on continuous charging under variable wind conditions and improved solar conversion through MOS tube PWM switching Use scenarios Offgrid cabin: Manage a small offgrid power system that combines a mediumsize wind turbine and solar array to keep a 12V battery bank charged for lighting, refrigeration, and essential loads. Remote telecom or monitoring station: Provide stable 12V charging from both wind and solar sources where grid power is unavailable and consistent charging under low wind is important. Recreational vehicle or marine application: Combine wind and solar inputs to maintain a 12V house battery bank aboard a boat or in an RV, with automatic discharge handling to protect the system during periods of generation. What makes it stand out Hybrid control tailored for combined wind and solar sources with dedicated MPPT for wind and MOS tube PWM for solar Continuous, efficient wind charging even at low wind speeds Smooth, stepless discharge control with external dumpload resistor support to handle excess energy without abrupt transitions This controller is a technical solution for 12V hybrid renewable systems that require efficient wind capture, improved solar conversion, and reliable energy management for midsize offgrid and mobile applications.
