5Pcs 1S MPPT Solar Panel Controller CN3791 6V 3A Solar Power Manager Module 18650 Lithium Battery Charging 3.7V

Feature Maximum power points tracking MPPT of solar cells is to ensure that photovoltaic cells always output maximum power when the light intensity changes so as to make full use of solar energy In general the MPPT function needs to be realized by using a switch mode DC DC converter to maximize the product output power of the output voltage and the charging current The maximum power points tracking function of photovoltaic cells is realized by switching step down mode dc DC conversion Its input voltage careach up to 28V which is very suitable for applications with large difference between input voltage and battery voltage Description 1 High end mPpt solar maximum power tracking charging management chip with trickle flow constant current and constant voltage charging management 2 Adopt imported high frequency and low on off internal resistance double mos tube large current diode high efficiency flat high power inductor alloy current detection resistor 3 Super large aluminum heat sink at the bottom to ensure the long time stable operation of large current 4 High speed and efficient charging method5 Dual status indicator the red light flashes and the green light is always on when the battery is not connected and the red light is on when the battery is charging and the green light is on at the same time when the battery full stop Functions Input voltage Select corresponding module according to the nominal voltage of solar panelOutput voltage Nominal 3 7V f
