DFRobot DFR0580 solar energy controller for 12V lead-acid battery

All about the product

A solar energy management module designed to charge a medium capacity, but high efficiency 12 V lead-acid battery. Suitable for use with devices up to 100 W voltage: 12 V lighting and security monitoring equipment, small robots, pumps, environmental monitoring stations. The controller has an MPPT (maximum power point tracking) function, which increases the output power of solar panels under varying sunlight conditions. Compared to other PWM solar controllers, the DFR0580 improves charging efficiency by up to 10-30%. Due to its compact size and lightweight, the module is easy to integrate into various projects.
