1. MPPT Technology: Features a 100A MPPT solar controller with an advanced MPPT maximum power point tracking algorithm, automatically identifying 12V, 24V, 36V, and 48V systems. Equipped with dual USB 5V charging ports, it rapidly tracks the maximum power point of the PV system in any environment, achieving a tracking efficiency of at least 99.5%. Significantly enhances the energy utilization efficiency of solar systems. 2. Multifunctional Design: Includes an LCD with backlight and clock display, offering 7 working modes: charging mode, lightsensitive mode, lightdelay control mode, universal control mode, manual control mode, and time control mode. 3. Safety Voltage Protection: Provides comprehensive protection features such as battery overvoltage protection, overcurrent protection, power failure protection, overcharge protection, deep discharge protection, reverse connection protection, and overheating temperature protection. 4. UserFriendly Design: The LCD dynamically displays operational data and device status, including working mode, battery voltage, PV charging current, battery discharge current, operating temperature, and delay time.
