Lithium battery 3.7V 4.2V lithium battery charging MPPT solar controller panel CN3791

Product Introduction

This module utilizes maximum power point tracking (MPPT) of solar cells to ensure that the photovoltaic cells continuously output maximum power when the light intensity changes, in order to fully utilize solar energy and achieve high conversion rates. In general, a switch mode DC-DC converter is required to achieve MPPT function and maximize the product of output voltage and charging current (output power). It is applied in solar photovoltaic systems to coordinate the operation of solar panels, batteries, and loads,
