1. High-end technology MPPT solar maximum power tracking charge management chip with turbulence, constant current, constant voltage charge management2. Adopt imported high frequency low conduction internal resistance double MOS tube, high current diode, high efficiency flat high power inductor, alloy current detecting resistor3. The bottom of the large aluminum heat sink ensures long-term stable operation at high currents4. High speed and efficient charging method5. Dual status indicator, the red light is always on when the battery is not connected, the red light is on when charging, the self-stop is full and the green light is on.Nominal 12V (10.8V 11.1V) full of junction voltage 12.6V lithium battery3 string lithium battery charging management board3A high current intelligent turbulence, constant current, constant voltage charging management boardSolar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell always outputs maximum power when the light intensity changes to make full use of solar energy. In general, it is necessary to implement the MPPT function with a switch mode DC-DC converter to maximize the product of the output voltage and the charging current (output power).CN3722 adopts switching buck mode DC-DC conversion to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 28V, which is very suitable for applications where the input voltage and battery voltage are relatively different.Input voltage: nominal 18V solar panel (no load 21V solar panel)Output voltage: nominal 12V (10.8 11.1V) full of junction voltage 12.6V lithium battery 3 string lithium battery charge managementOutput current: maximum constant current 3A (charge current is greater than 2A, please add heat)Wiring method: padIN+input positive, IN- input negative (SOLAR)BAT+ battery positive, BA- battery negativeColour:redMaterial:PCBSize:45 x 31mm Package Contents:1 x MPPT Solar ControllerOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
