CN3791 MPPT Solar Charger Module 12V Input Lithium-ion (3.7V/4.2V) Battery Charging Controller with JST IBAT22589

The MPPT Solar Charger Module CN3791 with JST PH 2.0 is a high-performance PWM switch-mode battery charger controller specifically designed for single-cell Lithium-ion (Li-ion) and Lithium Polymer (LiPo) batteries. Built around the CN3791 IC, this module features advanced Maximum Power Point Tracking (MPPT) logic that allows it to extract the maximum available energy from solar panels, even in fluctuating light conditions. This specific version is optimized for 12V nominal solar panels (with an input range of 5V-18V), converting the solar energy into a precision-regulated 4.2V charge.
