Introduction

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

equipments, 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 easy 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.
