Feature: 1. ADVANCED MICROCHIP TECHNOLOGY: The MPPT solar controller features a built in industrial microchip with excellent storage capabilities. The large LCD screen allows for easy adjustment of charge and discharge parameters, providing you with optimal control. 2. COMPREHENSIVE GUARD MECHANISMS: This controller includes internal over current, short circuit, open circuit, and reverse polarity guards, all of which are self recovering and do not damage the controller. The dual MOS reverse current guard ensures minimal heat generation. 3. ENHANCED ENERGY EFFICIENCY: Utilizing a maximum power point tracking algorithm, this solar controller can significantly boost the energy utilization efficiency of photovoltaic systems. It boasts an efficiency improvement of approximately 15% to 20% compared to traditional PWM charging. 4. CURRENT LIMITING CHARGING MODE: The MPPT solar controller features a current limiting charging mode that automatically reduces charging efficiency when the solar panel's output power exceeds rated current, ensuring safe and efficient operating at all times. 5. DUAL OR MULTI PEAK TRACKING TECHNOLOGY: When the solar panel is shaded or partially damaged, multiple peaks will appear, and the solar charger controller still accurately tracks the maximum point power.
