Product: Dual USB Photovoltaic PWM Charge Controller with Automatic 12V and 24V Identification and LCD Display Key benefits Keeps battery healthy: threestage charging management (bulk, absorption, float) controlled by PWM helps reduce overcharge and supports longer battery service life. Simple system setup: automatic 12V and 24V identification removes the need for manual configuration and reduces installation errors. Onboard monitoring: LCD display provides realtime information on panel input, battery status, load state, and charging mode for straightforward system checks. Device charging on the go: dual USB outputs provide convenient charging for phones, tablets, and other USB devices directly from the solar system. Versatile and compact: designed for small to medium photovoltaic systems where reliable charge regulation and user feedback are required. Main features Photovoltaic charge controller with PWM regulation for stable charging. Automatic identification of 12V and 24V systems to match common off grid configurations. Threestage charging management: bulk, absorption, and float stages to optimize battery charging. LCD display for monitoring voltage, current, charging stage, and load status. Dual USB outputs for charging mobile devices and small electronics. Load control terminals for switching lighting or small DC loads. Compatibility and performance Compatible with 12V and 24V photovoltaic systems and battery banks used in off grid and backup power setups. PWM regulation provides efficient, steady charging suitable for common leadacid and similar battery types used in solar installations. Designed to manage panel input and battery charging without complex configuration. Physical and installation notes Compact, mountable enclosure suitable for wall or panel mounting in a protected location. Clear terminal labeling and LCD readout simplify wiring and operation. Intended for use in typical residential, recreational, and light commercial solar applications. Use scenarios Remote cabin lighting and battery maintenance: manage a small solar array and battery bank while charging phones and powering LED lighting. RV or caravan energy system: automatically detect system voltage, control battery charging, and provide USB charging for devices during travel or campsite stays. Garden shed or outdoor workshop: run LED task lighting and keep a battery bank topped off for tools and small electronics. Why choose this controller Reliable PWM charging with automatic voltage identification and easytoread LCD feedback makes this controller a practical choice for compact solar systems that require dependable battery management and convenient device charging.
