Ensures safety with comprehensive protections
The DFRobot Solar Power Manager for 12V Lead-Acid Battery is a medium-power, high-efficiency solar power management module designed for IoT and renewable energy projects. It facilitates the charging of a 12V lead-acid battery with a maximum current of 4A using a standard 18V solar panel. This module is suitable for applications up to 100W, including 12V lighting equipment, security monitoring, small robots, pumps, and environmental monitoring stations.
It features Maximum Power Point Tracking (MPPT) to optimize solar panel output under varying sunlight conditions, enhancing charging performance by 10%-30% compared to common PWM solar controllers. The compact and lightweight design allows for easy integration into various projects. The module offers dual high-power outputs of 5V 5A and 12V 8A, along with dual USB outputs of 5V 2.5A each. Except for one USB output, all outputs can be controlled via I/O pins of most controllers, aiding in dynamic power management and reduced power consumption. Comprehensive protection functions ensure the safety and stability of the solar systems.
