Description

The DFRobot Solar Power Manager series is specifically designed to cater to IoT projects and renewable energy initiatives. These modules offer reliable and efficient embedded solar power management solutions for makers and application engineers.

The Solar Power Manager is a comprehensive and compact module that excels in small-scale power management with high efficiency. One of its notable features is the MPPT (Maximum Power Point Tracking) function, which optimizes the solar panel's performance to maximize power output. In addition to serving as a solar charger, this module can deliver a charging current of up to 2A to a 3.7V Li battery using an AC adapter (within 30V) or USB charger. It also includes three individual ON/OFF controllable DC-DC converters with outputs of 5V 1.5A, 3.3V 1A, and 9V/12V 0.5A, catering to various solar power projects and low-power applications.

To enhance system stability and safety, the module incorporates several protective functions. These include Li battery protection, protection against battery/solar panel reverse connection, output over-temperature protection, and over-current/short-circuit protection. By implementing these safeguards, the Solar Power Manager ensures a reliable and secure operating environment for the system.
