1. MPPT Technology: The 100A MPPT solar controller features 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, with a tracking efficiency of at least 99.5%. This significantly enhances the energy utilization efficiency of solar systems. 2. Multifunctional Design: Includes a backlit LCD indicator with a clock display and 7 working modes: charging mode, light control mode, light delay control mode, universal control mode, manual control mode, and timing control mode. 3. Safety Voltage Protection: The MPPT solar controller provides comprehensive voltage protection, including battery overvoltage and 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, such as working mode, battery voltage, PV charging current, battery discharge current, product operating temperature, and delay time.
