MPPT solar charge controller, Auto 12V/24V Available current ratings: 10A, 20A, 30A Color: MPPT 30A Key benefits Automatic 12V and 24V battery recognition simplifies installation and setup. MPPT tracking improves energy harvest from solar panels compared with fixedvoltage controllers. Flexible parameter settings and a large LCD make it easy to match the controller to different battery types and system needs. Builtin industrial microcontroller provides stable control and reliable operation. Fourstage PWM charge management supports proper battery charging and helps maintain battery life. Model specifications and maximum solar panel input 10A model For 12V battery: maximum solar panel input 25V, up to 120W For 24V battery: maximum solar panel input 50V, up to 240W 20A model For 12V battery: maximum solar panel input 25V, up to 240W For 24V battery: maximum solar panel input 50V, up to 480W 30A model For 12V battery: maximum solar panel input 25V, up to 360W For 24V battery: maximum solar panel input 50V, up to 720W Features MPPT solar charge control with selectable current ratings to match system size. Auto 12V/24V detection for straightforward compatibility with common battery systems. Large fixed LCD display with a userfriendly interface for status, voltage, current, and adjustable parameters. All charge and system parameters are configurable through the display for fine tuning. Builtin industrial microcontroller for precise charge control and system monitoring. Fourstage PWM charge management (bulk, absorption, float, equalize) to manage charging cycles and improve conversion performance. Compatibility and performance Works with leadacid battery types and other 12V and 24V battery systems that accept the listed charge profiles. Select model current rating to match solar array size and battery bank capacity. Ensure solar panel opencircuit voltage stays within the model limits: maximum 25V input for 12V systems and maximum 50V input for 24V systems. Typical applications Small offgrid cabins and tiny homes using a 12V or 24V battery bank for lights and appliances. Recreational vehicles and campervans for charging house batteries from portable or roofmounted panels. Marine and boating systems where reliable charge regulation and clear display are required. Remote signage, monitoring stations, and standalone lighting that need a compact, adjustable charge controller. What to consider when choosing a model Match the controller current rating to the maximum PV array wattage for your battery voltage using the specifications above. For higher PV power and larger battery banks choose the 20A or 30A models. Verify that panel opencircuit voltage does not exceed 25V for 12V battery installations or 50V for 24V battery installations. This MPPT solar charge controller combines automatic voltage selection, configurable charge parameters, a clear LCD interface, and fourstage PWM charge management to provide reliable charging and easy system setup for a variety of small to medium solar installations.
