Overview Solar Energy Manager is a solar power management module, which can charge the 3.7V 18650 lithium battery through solar panel or USB port. The module features MPPT (Maximum Power Point Tracking) and protection functions of battery charging and discharging. MPPT power point tracking can automatically adjust the charging power according to the input voltage, taking advantage of solar energy more efficiently. The protection circuit of charging and discharging can monitor the battery voltage in real time, preventing the battery from overcharging and over-discharging. It can protect the battery and prolong the battery life. Due to its excellent stability and efficient management of charging and discharging, it can be used in solar power generation, low-power IoT and other environmental protection projects.
