MPPT Solar Charge Controller 15A Adjustable Output 24V 36V 48V Step Up Renewed Overview This MPPT solar charge controller delivers a maximum charging current of 15A and an adjustable output to suit 24V, 36V, or 48V battery systems. The step up MPPT function optimizes power conversion from PV panels and allows flexible system configurations where panel voltage and battery voltage differ. Renewed condition. Key benefits Improved energy harvest: MPPT tracking increases usable power from solar panels compared to simple controllers, especially under variable light conditions. Flexible battery support: Adjustable output lets you set the controller for 24V, 36V, or 48V battery banks, reducing the need for multiple controllers. Step up capability: Step up function enables charging highervoltage battery systems from lowervoltage PV sources, simplifying panel and battery matching. Compact and practical: Designed for small offgrid and mobile applications where space and adaptability matter. Renewed and functional: Refurbished to operational condition to extend service life while maintaining functionality. Main features and functions Maximum charging current: 15A Output voltage: Adjustable to 24V, 36V, or 48V MPPT tracking algorithm: Maximizes power extraction from panels across changing irradiance and temperature Step up operation: Allows boosting input voltage to meet battery charging voltage requirements User setup: Simple output selection for target battery voltage Compatibility Intended for battery banks with nominal voltages of 24V, 36V, or 48V Suitable for small solar PV arrays where a 15A controller meets the system current requirements Works in systems where panel voltage may be lower than battery nominal voltage and step up functionality is required Practical applications Offgrid cabin or workshop: Charge a 24V, 36V, or 48V battery bank from a small PV array to power lighting, pumps, and electronics. Recreational vehicles and boats: Provide controlled charging for onboard battery systems where space and weight are limited. Remote equipment and backup power: Maintain battery banks for remote sensors, communications gear, or backup lighting using a compact solar setup. What to consider before installation Ensure total PV array current does not exceed 15A continuous charging current. Select the correct output voltage setting for your battery bank before connecting. Confirm panel voltage and the need for step up operation when planning the array and controller placement. Condition note Renewed product. Functionality restored and inspected for reliable operation. No additional or certification statements are included here. This MPPT 15A adjustable output step up controller is a practical choice when you need efficient solar charging, output flexibility across 24V, 36V, and 48V systems, and the ability to adapt panel and battery voltages in compact installations.
