Description Solar Controller SCDplus 40 A / 48 V suitable for lead (flooded, GEL, AGM) and LiFePO4 batteries. PWM charging control with deep discharge protection. High-quality solar charge controller with built-in USB interface. Precise and gentle charging of common solar battery types is possible thanks to the four different charging programs. Extensive protection measures against reverse polarity, overvoltage, and overload ensure safe operation of the solar charge controller. The intended overcharge protection and deep discharge protection support the longevity of the connected solar battery. Additionally, you can establish a connection between the solar controller and a PC using the USB interface, allowing you to program user-specific charging processes. The two built-in LEDs indicate the current charging level, warn of deep discharge, and display the status of the load output. The charging process, depending on the defined battery type and its charging termination voltage, takes place in a maximum of three stages.
