Electronic Modules Cn3791 MPPT Solar Panel Solar Charger Lithium Battery Charging Panel Modules

This Is a Solar Charger for Single Lithium Battery High Power Point Tracking (MPPT). This MPPT Solar Charger Enables You to Get as Much Power as Possible from Solar Panels Or Other Photovoltaic Equipment and Put It into Rechargeable Lithium Batteries. 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 Photovoltaic Cells Output High Power to Make Full Use of Solar Energy. Generally, the MPPT Function Needs to Be Realized by Using a DC-DC Converter in Switching Mode to Maintain the Product of Output Voltage and Charging Current (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 Four 2-Pin JST/Ph2.0 Connectors Are Pre-Installed.

By Default, We Set the Hold Voltage for MPPT. The Input Voltage Is 6V 12V Respectively (Corresponding to the Working Voltage of the Solar Panel 6V 12V), Which Is Very Suitable for Applications with Large Input Voltage and Battery Voltage Differential Pressure.

When the Current Output Capability of the Input Power Supply Decreases, Cn3791 Internal Circuit Can Automatically Track the High Power Point of the Solar Panel. Users Do Not Need to Consider the Bad Situation, and Can Make Use of the Output Power of the Solar Panel to a Large Extent, it Is Very Suitable for the Application of Using Solar Panels to Supply Power.
