Versatile power management: Supports 12V and 24V systems with automatic recognition for easy integration. Convenient device charging: Builtin USB port powers small electronics directly from the controller. Reliable regulation: PWM charging helps improve battery utilization and reduce overcharge risk. Main features Function: Solar charge controller with PWM regulation, battery protection, and system status display. Compatibility: Works with 12V or 24V solar systems; suitable for leadacid battery types commonly used in offgrid setups. 20A rated current supports small to medium solar arrays and loads within controller limits. Performance: Up to 20A charge/discharge; MOS anti backup circuit mitigates reverse current; LCD provides realtime operating information; USB output for lowpower devices. Controls and interface: Buttonoperated LCD for mode checks and settings; terminal blocks for solar panel, battery, and load connections; dedicated USB port. Build: Circuit boardbased controller designed for practical, stable installation in DIY and prototyping scenarios. Suggested applications RV or camper power system: Regulate a 12V battery bank from rooftop solar panels while charging a phone or GPS via the USB port. Small offgrid cabin: Manage a 24V solar setup to keep lighting and basic electronics powered with easy status checks on the LCD. Portable field kit: Use with a compact solar panel to maintain a battery for trail cameras, sensors, or small tools during outdoor projects. What makes it stand out MOS antibackflow circuit designed to reduce reverse current and help protect batteries. LCD interface for quick diagnostics and setup without additional tools. Dualsystem compatibility (12V/24V) at 20A for flexible deployment across multiple projects. Specifications System voltage: 12V or 24V (auto recognition) Rated current: 20A Control method: PWM Display: LCD screen with status indicators Ports: Solar input, battery, load terminals; 1 x USB output Circuit type: MOS antibackup design to inhibit reverse current Usage notes Ensure solar panel and load ratings do not exceed 20A through the controller. Match battery type and system voltage before connection. Follow correct wiring : battery to controller first, then solar panel, then load. Disconnect in reverse .
