CN3791 MPPT solar panel solar charger 3.7V 4.2V lithium battery charging board module

CN3791

Model:CN3791

Manufacturer:ANSC/OEM

Package:module

Detail

Product Description


This module has three input voltages of 6V/9V/12V, corresponding to the operating voltage (nominal voltage) of the solar panel, which is 6V/9V/12V.


\This MPPT solar charger allows you to extract as much electricity as possible from solar panels or other photovoltaic devices and pack it into a rechargeable lithium battery.


Product Features


Input voltage: Select the corresponding module based on the nominal voltage of the solar panel (6/9V/12V)


Output voltage: nominal 3.7V full charge termination voltage 4.2V lithium battery


Working environment temperature:- 40°C+85°C


When the current output capability of the input power supply decreases, the internal circuit of CN3791 can automatically track the maximum power point of the solar panel


Charging current can reach 2A


PWM switching frequency: 300KHz


Constant voltage charging voltage: 4.2V+1%


The constant current charging current is set by an external resistor


Perform trickle charging on batteries with deep discharge


The product has automatic recharging function and soft start function


When charging, the CH light (red light) will remain on and the 0K light will turn off (blue light); When fully charged, the CH light will flash and the OK light will remain on
