CN3791 Solar Charge Controller Board MPPT 12V Solar...

Description:

CN3791 solar charge controller board has the functions of automatic charging, battery overvoltage protection, charging state and end of charging state indication, maximum power point tracking of solar panel and complete single lithium battery charging management. In general, switching mode DC-DC converter is needed to realize MPPT function, which keeps the maximum product of output voltage and charging current (output).

Package Including
1 * CN3791 solar charge controller board

Solar Charge Controller Module is designed to charge a single polymer Li ion battery and the load should be in parallel with the battery
12V Solar Panel Charge Regulator can be used for trickle charging of discharge battery, with automatic charging and battery overvoltage protection
Li Battery Charging Module is equipped with a cn3791 power tracking battery charging circuit and pre installed with four 2-pin JST / ph2.0 connectors, which default to the MPPT holding voltage
The size of the CN3791 Solar Charge Controller Board is 4.5x2x0.95 cm / 1.77×0.79×0.37 inch. It is small in size and light in weight. It is easy to store and use and does not occupy too much space
MPPT Solar Battery has three versions of input voltage 6V / 9V / 12V (solar panel working voltage 6V / 9V / 12V), which is very suitable for applications with large difference between input voltage and battery voltage
