MPPT Solar Charge Controller with Dual USB Auto Recognition and Builtin Timer A reliable controller for managing solar input, charging batteries, and powering USB devices. This MPPT controller increases usable energy from your solar panels while protecting batteries and connected equipment. Key benefits Higher energy harvest: MPPT tracking optimizes the panel output to increase conversion from solar to battery, improving charging efficiency in changing light conditions. Convenient device charging: Two USB ports automatically recognize connected devices to deliver appropriate charging current for phones, tablets, and small electronics. Scheduled load control: Builtin timer lets you program lighting or other DC loads to run on set schedules, reducing manual work and conserving battery power. Battery and system protection: Builtin overcharge and overload protection help prevent battery damage and reduce the risk of system faults. Clear system visibility: Large LCD display provides realtime information on voltage, charge current, timer status, and basic system state for quick monitoring and troubleshooting. Main functions and attributes Maximum Power Point Tracking (MPPT) to optimize solar panel output and improve charging performance. Dual USB ports with auto recognition for smart charging of consumer devices. Integrated timer for programmable onoff cycles of DC loads. Large LCD display for clear status, values, and mode indication. Protections include overcharge prevention and overload protection to safeguard battery and loads. Compact design suitable for small to medium offgrid solar setups; durable enclosure for typical installation environments. Compatibility and performance Designed for use with solar panels and battery systems in offgrid or auxiliary power installations. Intended for managing DC loads and charging common mobile devices via USB. Works in systems where MPPT regulation provides better performance than basic PWM control, particularly under fluctuating sunlight. Practical applications Recreational vehicle or camper: Manage solar charging to a house battery while providing USB charging for phones and tablets and using the timer to run interior lights after dusk. Remote cabin or shed: Control solar charging and automatically schedule exterior lighting or small DC appliances to run only when needed. Small boat or marine craft: Maintain battery health from solar panels, charge onboard devices from USB ports, and set lighting or ventilation cycles using the timer. What to expect A functional, easytoread controller that helps maximize solar input, protect batteries, and conveniently charge USB devices while offering timer control for routine load management. Suitable for hobbyist and smallscale offgrid systems where clear monitoring and basic protections are required.
