Size: Wind400W+Solar500W Overview This wind and solar hybrid charge controller is built for reliable offgrid charging where both wind and solar resources are available. It combines boost MPPT technology for the wind generator with PWM charging for the solar array, automatic battery recognition, and a color LCD with a simple 4key user interface. The result is steady, efficient charging and flexible compatibility with common battery systems. Key benefits Better energy capture at low wind speeds: The wind charging circuit uses boost MPPT technology to continue harvesting power when wind is weak, increasing usable energy from small or variable turbines. Reliable solar charging: Solar input uses PWM charging for straightforward, stable regulation when sunlight is available. Simplified setup and stable control: After selecting the battery type the controller applies optimized parameters automatically. Users can also settings to match specific system requirements while charging voltage control remains stable. Broad battery compatibility: Automatic recognition of 12V, 24V, and 48V systems and selectable charging modes for leadacid battery, ternary lithium battery, lithium iron phosphate, and a custom fourth battery type improve conversion efficiency and protect battery health. Clear status and easy operation: Color LCD provides comprehensive information with a clear interface. The 4key manmachine interface makes navigation and parameter adjustment fast and intuitive. Independent boost circuit: Dedicated boost stage improves conversion rates for the wind input and enables consistent performance across battery types and voltages. Technical highlights Size configuration: Wind400W plus Solar500W Wind input: boost MPPT technology for continuous efficient charging at low wind speeds Solar input: PWM charging regulation Battery system support: automatic 12V 24V 48V recognition Selectable battery modes: leadacid battery, ternary lithium battery, lithium iron phosphate, custom battery mode User interface: color LCD display with 4key operation : adjustable parameters for users who require fine tuning Practical applications Offgrid cabin or rural home: Combine a small wind turbine and rooftop solar to charge a 12V 24V or 48V battery bank for lighting, appliances, and storage where grid power is unavailable. Recreational vehicle and marine systems: Use in RVs or boats that rely on mixed wind and solar conditions to maintain battery state of charge and reduce engine or generator runtime. Remote telecom, pump, or sensor sites: Provide stable, autonomous power for remote installations that experience variable wind and solar input and need consistent battery charging. What it solves Reduces energy loss when wind or sun is intermittent by optimizing each input type Simplifies system commissioning with automatic voltage detection and preset battery profiles Gives operators direct control through a readable color display and easy buttons while protecting batteries through controlled charging modes This controller is suitable for hybrid systems specified as Wind400W plus Solar500W and for battery configurations up to 48V using the supported battery chemistries and custom mode options.
