12V/24V Solar Charge Controller with LCD Display Description A versatile solar charge regulator designed for straightforward control of battery charging and discharging. The unit features an LCD display for clear status and parameter adjustments, automatic 12V/24V system identification, selectable battery chemistry modes (B1, B2, B3), and dual USB ports for charging portable devices. Constructed from durable materials for longterm use and engineered to improve energy conversion from solar panels to batteries. Key benefits Simple monitoring and control: The builtin LCD shows charging status and basic settings, making it easier to manage charge and discharge cycles without specialized tools. Multichemistry compatibility: Supports lead acid battery with automatic 12V/24V identification (B1), lithium ion battery mode (B2), and lithium iron phosphate battery mode (B3), so one controller fits multiple battery types. Efficient energy use: Designed to improve conversion efficiency between solar panels and battery storage, helping maximize usable power from the array. Convenient device charging: Dual USB ports provide ondemand power for phones, lights, and other small USB devices directly from the controller. Durable construction: Made from materials selected for lasting use in typical offgrid and portable solar setups. Primary functions and attributes Function: Regulates solar panel input to charge batteries and manage discharge; provides monitoring via LCD. Compatibility: Automatic identification of 12V or 24V systems; selectable modes for B1 (lead acid 12V/24V), B2 (lithium ion), and B3 (lithium iron phosphate). Controls: LCD display for viewing status and adjusting settings related to charge and discharge. Ports: Dual USB outputs for charging external devices. Performance: Improves conversion efficiency from solar panel to battery through regulated charging. Typical applications Small offgrid power systems: Use with a compact solar array and battery bank to manage charging and maintain battery health for cabin lighting and electronics. Portable solar generators: Integrate into generator setups to regulate battery charging and provide USB charging for phones and small devices. Recreational vehicles and boats: Manage charging from rooftop panels, select the appropriate battery chemistry mode, and power USB accessories while on the move. Operation notes Select the battery mode that matches your battery: B1 for lead acid with 12V/24V automatic detection, B2 for lithium ion, B3 for lithium iron phosphate. Use the LCD to monitor charging status and to adjust basic parameters as needed for your system. Ensure wiring and panel sizing follow your battery and panel specifications to achieve performance. This controller is intended for use in small to medium solar charging installations where clear monitoring, multichemistry support, and convenient USB charging are required.
