DFRobot Solar Power Manager for 12V Lead-Acid Battery with MPPT

The DFRobot DFR0580 is a medium-power, high-efficiency solar management module engineered for 12V lead-acid batteries, delivering 4A max charging current via 18V solar panels (15–25V input). Featuring fixed 18V MPPT technology, it maximizes solar energy conversion with 94% average efficiency—10–30% higher than standard PWM controllers—while supporting dual high-power outputs (5V/5A + 12V/8A) and dual USB ports (5V/2.5A each) for industrial IoT, street lighting, and environmental monitoring systems. With comprehensive protections (overcharge/discharge, reverse polarity, short-circuit) and -40°C to 85°C operational range, it ensures reliability in harsh environments, making it ideal for 100W solar projects requiring robust, maintenance-free power management 🔋.
