Features 1、The input and output terminals are made of high-side switching power supply for high-frequency low-impedance electrolytic capacitors (LOW ESR) to ensure output ripple and effectively filter out switching power supply faults. 2、MPPT solar maximum power point tracking, automatic intelligent charging management, low power consumption. 3、The maximum conversion efficiency is 93% and the maximum value is 95% depending on the lighting conditions. 4、Automatic intelligent three-stage charging mode. The self-tracking solar charging current is automatically resized. 5、With a no-load current of 3 mA, even a very weak morning sun can be easily and automatically activated without manual switching. 6、With input reverse polarity protection. The ultra-low dropout designed exclusively prevents reverse polarity protection of MOS transistors, and reverse input does not work. 7、With output reflow protection. Effectively prevent the charge meter of the nighttime reverse battery! Specification Item Type:Solar Panel Regulator 6V battery can charge 12 or 8.4V, 12.6V, 16.8V lithium battery 7.2V, 10.8V, 14.4V lithium iron phosphate battery 2-4 series lithium battery, lithium iron phosphate charging management board Output Current: 5A Maximum Charging Indicator: Yes. The fast red and blue lights of the fast red light flash alternately. Automatically stopped. MPPT Function: MPPT maximum power point automatic tracking, maximizing the use of solar charging Operating Temperature: Industrial Grade (-40℃ to + 85℃) Load Adjustment Rate: ±1% Connection: With Terminal Debugging method: Step 3: Repair the depleted battery and monitor the charging current on the output string ammeter. Adjust the potentiometer with MPPT until the charging current is maximum. Transfer method instead of using solar power: Charge management board function: 1. Solar cell maximum power point tracking, output current is greater than solar panel current, true ultra-efficient MPPT, support 8-28V, 100W solar high current charging, it is recommended that each module of solar panel be connected in parallel to expand charging Current Package List 1 x Solar Panel Regulator
