DFRobot is launching a brand new series - Sunflower, focusing on high-efficiency, small power solar energy management for IoT projects and renewable energy applications.

Note: We are now stocking the v1.1 Revision Battery (BAT IN) overcurrent and over-discharge protection is added to improve battery safety. It can be used for any 3.7V LiPo battery, whether it has integrated protection circuits or not. v1.0 Requires the battery used to have these integrated.

Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel. It features as MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel. Apart from serving as a solar charger, the module can provide up to 900mA charging current to 3.7V Li battery with USB charger. The ON/OFF controllable DC-DC converters with 5V 1A output satisfies the needs of various solar power projects and low-power applications. The module also employs various protection functions, such as battery/solar panel reverse connection protection, output over temperature and over current/short circuit protection, which greatly improves the stability and safety of the system.
