The DFRobot Solar Power Manager 5V (DFR0559) is a compact, high-efficiency module designed to revolutionize solar-powered IoT and low-energy applications. Engineered with MPPT (Maximum Power Point Tracking) technology, it maximizes solar panel efficiency while supporting dual charging modes (solar/USB, 900mA max) for 3.7V Li-ion batteries. With 5V/1A regulated output, comprehensive protection circuits, and ultra-low quiescent current (<1 mA), this module ensures reliable power for projects like environmental monitors, solar robots, and portable chargers—all in a robust industrial-grade package (-40°C to 85°C tolerance) 🌞.

⚡ Key Features

  • 🌞 Smart MPPT Optimization

    • Constant-voltage algorithm maximizes solar harvest under varying light conditions, boosting efficiency by 15-20% vs. standard chargers

    • 4.5V–6V solar input compatibility with 5V panels (≤10W recommended)

  • 🔋 Dual Charging & Power Management

    • Solar/USB charging: 900mA max current with auto-priority switching (USB overrides solar)

    • 5V/1A regulated output with ON/OFF control via jumper or MCU GPIO—ideal for low-power sleep modes

  • 🛡️ Industrial-Grade Protection

    • Battery safeguards: Over-charge (4.2V±1%), over-discharge, over-current, and reverse-connection protection (V1.1 upgrade)

    • Output safety: Short-circuit/over-current shutdown for connected devices

  • 📦 Compact & Efficient Design

    • 33×63mm footprint with included cooling kit (aluminum fin + thermal pad) for sustained 900mA loads

    • 73% solar/USB charge efficiency and 86% regulated output efficiency (3.7V battery input)
