Description

12V MPPT Solar Charge Controller for 3S Lithium ion Battery ensures that the photovoltaic cell always outputs the maximum power in order to fully utilize the solar energy when the light intensity changes. In the general case, the MPPT function needs to be implemented with a switch mode DC-DC converter to maximize the product (output power) of the output voltage and the charging current.

This 12V MPPT Solar Charge Controller for 3S Lithium ion Battery uses CN3722 chip, which adopts the switching step-down 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 with large difference between input voltage and battery voltage.
