Product overview A PWM solar charge controller that automatically detects system voltage and adapts charging behavior to protect batteries and improve system efficiency. Designed for offgrid solar installations that require reliable charging control, temperature compensation, and easy onsite configuration. Key benefits Automatic voltage identification: Automatically detects 12V, 24V, or 48V systems and selects the appropriate PWM charging profile, eliminating manual setup errors and simplifying installation. Extended battery life: Temperature compensation charging automatically adjusts charging and discharging parameters based on ambient temperature, helping to reduce battery stress and extend service life. Easy onsite control: Builtin LCD display and user interface allow quick parameter setting, modification, and status monitoring. Intelligent memory retains settings after power interruption for consistent operation. Safer, more reliable operation: Integrated selftest routines and electronic protection functions identify installation mistakes and system faults early, reducing downtime and improving energy conversion efficiency. Features Automatic 12V, 24V, 48V identification for efficient PWM charging Temperature compensation charging algorithm for adaptive charge and discharge control LCD display for local control, parameter configuration, and status feedback Intelligent memory function to preserve settings during power loss Comprehensive selftest and protection functions to detect installation errors and system failures Compatibility and performance Compatible with typical offgrid solar battery systems using 12V, 24V, or 48V configurations Suited to systems that use PWM charging methods and benefit from temperaturecompensated charge control Designed to improve charger reliability and maintain efficient energy transfer between solar panels and battery storage Practical applications Remote offgrid cabin or cottage power systems where automatic voltage detection and temperature compensation reduce maintenance needs Recreational vehicles or boats that use 12V or 24V battery banks and require robust, userfriendly charge control Small commercial or lighting systems with 24V or 48V battery setups that need reliable protection and easy onsite configuration What you get A useroriented PWM charge controller that simplifies setup, adapts charging to realworld conditions, protects battery health, and supports reliable offgrid operation through clear local controls and builtin protection features.
