The CN3791 Charging Module is a compact and efficient lithium battery charging solution designed specifically for solar-powered applications. Utilizing Maximum Power Point Tracking (MPPT) technology, this module ensures optimal energy harvesting from photovoltaic sources such as solar panels. It is ideal for charging single-cell 3.7V lithium-ion or lithium-polymer batteries with precision, safety, and high efficiency.
The module is plug-and-play, with JST-PH2.0 connectors for easy integration. Simply connect a 6V solar panel to the input and a compatible lithium battery to the output. The onboard CN3791 chip intelligently adjusts the charging profile to match the solar panel's maximum power point, automatically optimizing energy transfer even under changing light conditions.
Features:
-
MPPT Functionality: Actively tracks the maximum power point of the solar panel to maximize energy transfer.
-
Input Voltage Compatibility: Optimized for 6V solar panels or DC sources with similar output.
-
Adjustable Charging Current: Constant current charging up to 2A, adjustable via external resistor.
-
