Product Description
Note: The input voltage of this module is 12V, which corresponds to the working voltage of the solar panel (nominal voltage) 12V
This is a solar charger for single-cell lithium battery High Power Point Tracking (MPPT). This MPPT solar charger allows you to get as much electricity as possible from solar panels or other photovoltaic devices and load it into a rechargeable lithium battery. It is very easy to use, just insert the solar panel into one side of the solar charger, then insert the battery into the other side, and you can start charging!
Solar Power Point Tracking (MPPT) is to ensure that the light intensity changes and the photovoltaic cells output high power to make full use of solar energy. Usually, a switch-mode DC-DC converter is needed to realize the MPPT function, keeping the product of output voltage and charging current large (output).
The output of the solar charger is designed to charge a single polymer lithium-ion battery. The load should be connected in parallel with the battery. Each solar charger is equipped with CN3791 power tracking battery charging circuit and pre-installed with four 2-pin JST/PH2.0 connectors.
By default, we set the hold voltage for MPPT. The input voltages are 6V 12V (corresponding to the working voltage of the solar panel 6V 12V), which is very suitable for applications where the input voltage and the battery voltage difference are large.
When the current output capability of the input power supply decreases, the internal circuit of CN3791 can automatically track the high power point of the solar panel. The user does not need to consider the bad situation, and the output power of the solar panel can be utilized to the greatest extent, which is very suitable for the application of power supply by the solar panel.
