The DFRobot Solar Power Manager series is specifically designed for IoT projects and renewable energy applications. These modules offer secure and highly efficient embedded solar power management solutions, catering to the needs of makers and application engineers. One notable module in this series is the Solar Power Manager for 12V Lead-Acid Battery. It operates at a medium power level and boasts high efficiency.
This solar power management module enables the charging of a 12V lead-acid battery using a standard 18V solar panel, with a maximum charging current of 4A. It is well-suited for applications up to 100W, including 12V lighting equipment, security monitoring systems, small robots, pumps, and environmental monitoring stations.
One key feature of this module is its MPPT (Maximum Power Point Tracking) function, which optimizes the output power of the solar panels across different sunlight conditions. By employing MPPT instead of common PWM solar controllers, the charging performance can be improved by 10-30Percent. Additionally, its compact size and light weight make it convenient to integrate into your projects seamlessly.
The Solar Power Manager for 12V Lead-Acid Battery offers two high-power outputs: 5V 5A (OUT1) and 12V 8A (OUT2). It also provides dual USB outputs, delivering 5V 2.5A (USB1/USB2). With the exception of USB1, all outputs can be controlled using the I/O pins of most controllers (compatible with both 3.3V and 5V). This capability allows for dynamic powering of loads and helps reduce overall power consumption.
To ensure the safety and stability of solar systems, various protection functions are incorporated into this module. These protections safeguard against potential issues, ensuring reliable operation of the solar power management system.
FAQs:
Q: What is the Solar Power Manager for 12V Lead Acid Battery used for?
A: The Solar Power Manager regulates the charging and discharging of a 12V lead-acid battery using solar energy. It ensures efficient solar power management, including overcharge protection, discharge control, and battery health monitoring.
Q: What are the main features of the Solar Power Manager?
A: Key features include MPPT (Maximum Power Point Tracking) technology for efficient solar charging, overcharge and deep discharge protection, load control, battery status monitoring, and a user-friendly LCD display for real-time information.
Q: How do I connect the Solar Power Manager to my solar panel and battery?
A: Connect the solar panel to the “PV” terminals, the 12V lead-acid battery to the “BAT” terminals, and your load (such as lights or devices) to the “LOAD” terminals. Follow the included wiring diagram to ensure proper connections.
Q: What is MPPT technology, and why is it important?
A: MPPT (Maximum Power Point Tracking) technology optimizes the power output from your solar panels by adjusting the charge rate to match the battery’s needs. It increases the efficiency of solar power conversion and improves battery charging.
Q: What kind of maintenance does the Solar Power Manager require?
A: The Solar Power Manager requires minimal maintenance. Regularly check connections, ensure clean solar panels, and monitor battery health through the LCD display. No other routine maintenance is necessary for the controller itself.
