This battery charging controller delivers safer, more efficient charging for 12 volt and 24 volt battery systems. It combines a 3level PWM charging algorithm, automatic system detection, temperature compensation, and multiple protections to keep batteries healthy, reduce maintenance, and provide clear status at a glance. Key benefits Extends battery life: The 3level PWM charging algorithm balances charging and discharging to reduce stress on batteries and help maintain capacity over time. Automatic and adaptive: Automatically recognizes 12V and 24V systems, adjusts charging parameters accordingly, and applies temperature compensation to optimize charge under varying conditions. Secure operation: Builtin protection against overcharge, overdischarge, overload, and short circuits helps prevent damage to batteries and connected equipment. Clear monitoring and easy control: A graphic LCD screen and a simple, easytooperate panel make system status, charging stage, and fault conditions easy to see and manage. Features and performance 3level PWM charging algorithm for staged charging and balanced battery care. Automatic 12V and 24V detection with automatic parameter adjustment for compatibility with common battery systems. Temperature compensation to adjust charging behavior with ambient temperature changes and maintain reliable performance. Protection functions include overcharge protection, overdischarge protection, overload protection, and shortcircuit protection. Graphic LCD display for clear readout of charging status and easytouse control panel for straightforward setup and operation. Compatibility and typical applications Compatible with 12V and 24V battery banks commonly used in automotive, marine, and offgrid systems. Well suited for solar offgrid installations to regulate charging from solar arrays and protect battery banks. Ideal for maintaining batteries in RVs, trucks, and boats where automatic voltage recognition and temperature compensation improve reliability. Practical usage examples Offgrid cabin: Manage a 12V or 24V battery bank charged by a solar array, with automatic detection and temperature compensation to maintain battery health through seasonal temperature changes. Recreational vehicle: Keep RV batteries properly charged and balanced while parked or during use, with clear LCD feedback and builtin protections to avoid overcharge or deep discharge. Marine application: Protect marine batteries from overload and short circuits while providing a clear display and easy operation for routine checks and monitoring. Why choose this controller Designed to make battery charging safer and more reliable through intelligent charging stages, automatic system matching, and multiple safety protections. Provides practical visibility and simple controls so users can monitor performance and respond quickly if intervention is needed. Supports common 12V and 24V setups used in vehicles, boats, and offgrid systems without manual configuration, reducing setup time and potential errors.
