CN3791 MPPT Solar Power Panel Lithium Battery Charging Module 6V 9V 12V Solar Panel

Note: This module has input voltages of 6V and 12V, corresponding to the operating voltage (nominal voltage) of the solar panels at 6V and 12V respectively. The shipped version is the 12V one.

This is used for high-power tracking of single-cell lithium batteriesMPPT) solar charger.This oneMPPTA solar charger enables you to get as much electricity as possible from solar panels or other photovoltaic devices and pack it into rechargeable lithium batteries.Very easy to use, just insert the solar panel into one side of the solar charger and then insert the battery into the other side, and you can start charging!

Solar High Power Tracking (MPPT) is to ensure that when the light intensity changes, the photovoltaic cell outputs high power to fully utilize solar energy.Usually, it requires using a switch modeDC-DCConverter to achieveMPPTFunction, maintains the output voltage and charging current product maximized (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 comes equipped withCN3791..Power Tracking Battery Charging Circuit, and Pre-Installed Four2NeedleJST / PH2.0Connector.

By default, we set it toMPPTThe voltage has been set to maintain.The input voltage is 6V each 12V(Corresponds to the operating voltage of the solar panel 6V 12V), making it ideal for applications with large input voltage and battery voltage differences.

When the input power's current output capability decreases,CN3791The internal circuit can automatically track the high-power point of the solar panel, eliminating the need for users to consider bad conditions. It maximizes the output power of the solar panel and is very suitable for applications powered by solar panels.
