CN3767 12V 4A lead acid battery solar charger

Product detailed description

CN3767 is specially designed for 12V lead-acid battery charging with maintenance charging, constant current charging, overcharging and maintenance charging.
In overcharging and float charging mode, the regulation voltage is set internally. The constant charging current is programmable using a single sensing resistor. CN3767 can be powered by solar panel with MPPT function.
Deeply discharged batteries are automatically charged to 17.5% of the programmed constant charging current until the cell voltage exceeds 75% of the regulation voltage in overcharge mode. Charging is terminated when the charging current drops to 38% of the value
constant charging current, then the CN3767 will enter float charging mode. A new charge cycle will automatically restart if the battery voltage drops below 83.95% of the overcharge voltage in float charge mode. The CN3767 will automatically enter sleep mode when the input voltage is lower than the battery voltage.
Other features include undervoltage lockout and status indication etc

The module includes two LEDs. Red color indicates charging. The green colour indicates a complete charge.

Maximum Power Point Tracking (MPPT) of the solar cell ensures that the PV cell always puts out maximum power to fully utilize the sun's energy when the light intensity changes. In general, the MPPT function must be implemented with the switch mode of the DC-DC converter to maximize the output power of the output voltage and charging current.
