MPPT Solar Charge Controller with QC3.0 USB and LCD Screen (10A) Overview A compact MPPT solar charge controller designed for small off grid solar systems. Integrates Maximum Power Point Tracking charging, Quick Charge 3.0 USB output, a clear LCD status display, and multiple protection functions to protect batteries and connected devices while improving charging efficiency. Key benefits Improved charging efficiency: MPPT tracking optimizes power harvested from solar panels to charge batteries more effectively than basic PWM controllers. Fast device charging: Builtin QC3.0 USB output provides faster charging for compatible phones and tablets while the system is running. Battery protection and reliability: Multiple protection features reduce the risk of battery overcharge, deep discharge, wiring faults, and overheating. Easy system monitoring: LCD screen displays real time status including voltages and current so you can check system performance at a glance. Compact and simple to install: Small footprint and straightforward wiring make it easy to add to existing small solar setups. Core functions and attributes MPPT solar charge regulation for optimized solartobattery conversion. Quick Charge 3.0 USB output for accelerated charging of compatible mobile devices. LCD screen for clear readouts of battery voltage, charging current, and operating status. 10A maximum charging current rating suitable for small solar arrays and battery banks within this current limit. Multiple protection features including overcharge protection, overdischarge protection, reverse polarity protection, short circuit protection, and overtemperature protection. Durable, compact enclosure designed for indoor or sheltered outdoor installation and convenient mounting. Compatibility and performance Designed for use with solar panels and DC battery systems when total charging current does not exceed 10A. USB QC3.0 port is compatible with devices that support Quick Charge 3.0 protocols and will deliver faster charging to supported devices. MPPT operation increases available charging power from panels, improving performance in varied light conditions and partial shading compared to non MPPT controllers. Practical use scenarios Off grid cabin lighting and battery charging: Use the controller to charge a small battery bank for LED lighting and low power appliances while monitoring system status on the LCD. RV or boat accessory power and phone charging: Manage solar charging for onboard batteries and provide fast QC3.0 charging for mobile devices. Garden shed, workshop, or backup power for small electronics: Keep a compact solar system organized and protected while ensuring efficient battery charging and safe operation. What it solves Prevents battery damage from overcharging or deep discharge through automated protection and regulation. Maximizes usable solar power by tracking the maximum power point of panels. Provides a convenient fastcharging USB port for mobile devices without compromising battery management. Simplifies monitoring of system performance via a builtin LCD display. What to expect A reliable, compact MPPT controller with Quick Charge 3.0 USB and multiple protection functions intended for small scale solar installations. Appropriate where a 10A maximum charging current is sufficient and where visible system status and device charging convenience are desired.
