INTRODUCTION

The DFRobot Solar Power Manager series are designed for IoT projects and renewable energy projects, providing safe and high-efficiency embedded solar power management modules for makers and application engineers. This medium-power high-efficiency solar power management module allows you to charge a 12V lead-acid battery with a maximum of 4A using a standard 18V solar panel.

Check the brief specification for all Solar Power Manager Series Products.

Solar Power Manager For 12V Lead-Acid Battery is a medium-power high-efficiency solar power management module, which is able to charge a 12V lead-acid battery with a maximum of 4A using a standard 18V solar panel. It is suitable for applications within 100W, such as 12V lighting equipment, security monitoring, small robots, pumps or environmental monitoring stations. It features as MPPT(Maximum Power Point Tracking) function, maximizing the output power of solar panels under various sunlight. Compared with common PWM solar controllers, it can improve charging performance by 10%-30%. Benefited from its small size and light weight, it is easier to embed it in your projects. The module provides dual high-power outputs 5V 5A (OUT1) and 12V 8A (OUT2) and dual USB outputs 5V 2.5A (USB1/USB2). Except USB1, all outputs can be turned ON/OFF by I/O pins of most controllers (3.3V/5V compatible). This feature helps to dynamically power loads and reduce power consumption. Various protection functions are also employed to ensure the safety and stability of the solar systems.

Note 1: OUT1/USB1/USB2 shared 5A current driving capacity (peak current 8A), that is, the total output power of the three outputs should not exceed 5V*5A=25W (peak 40W).

Note 2: To ensure whether the communication devices you use are compatible with the protocols listed, please consult your communication device manufacturer or retailers for details. If your device does not support the USB charging protocol mentioned above, usually it will limit the charging power to 5V*1A=5W for security sake. This is not caused by the failure of the USB output or insufficient output capability.
