1  Introduction
GSC-F2448 solar charge controller is a highly intelligent charge controller with Maximum Power Point Tracking(MPPT), which can charge 24V/48V batteries with battery voltage level automatic identification. Advanced professional MPPT control algorithm is applied to achieve the optimal and intelligent “MPPT + SOC” charge control. It is especially designed to be low own power consumption by applying advanced low-power, high-performance microcontroller, PWM charging mode and other dedicated hardware circuits. The controller is robust, maintenance-free and user-friendly with the reverse polarity protection, lightning protection, electronic fuse and automatic detection of faulty battery.
