Χαρακτηριστικά

Solar Power Manager is a complete small power and high-efficiency solar power management module. 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 2A charging current to 3.7V Li battery with AC adapter (within 30V) or USB charger, three individual ON/OFF controllable DC-DC converters with 5V 1.5A, 3.3V 1A and 9V/12V 0.5A outputs. These features satisfy the needs of various solar power projects and low-power applications. The module also employs various protect functions, such as Li battery protection, 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.

Applications

Smart solar environment monitor system
Solar powered robot
Small solar street lamp
Solar power bank
