This solar charge controller provides reliable PWM charging and automated light control for small to medium off grid lighting systems. It safeguards batteries and solar panels while simplifying night time lighting, making it a practical component for outdoor lighting and solar power setups. Key benefits Efficient battery protection: PWM charging control helps prevent overcharging and overdischarge, preserving battery life and keeping systems ready for use. Solar panel protection: Open circuit antiovercharge protection reduces the risk of damage to the solar panel by preventing harmful charging conditions. Wide battery compatibility: Works with VRLA, GEL, and ironbased lithium batteries, allowing use with multiple storage battery types. Automatic lighting control: Detects ambient light to switch floodlights on at sunset and off at the preset level or at sunrise, reducing manual intervention. Fine sensitivity adjustment: Nine adjustable light sensitivity grades let you set the exact threshold for turning lights on and off. Main functions and performance PWM charging regulation that delivers steady, controlled charging current to batteries. Open circuit antiovercharge protection to protect the solar panel from excessive charging conditions. Lightdependent switching using a dusktodawn control scheme; configurable off timing or automatic turnoff at sunrise. Ninestep sensitivity adjustment for precise control over dusk trigger levels. Practical attributes Function: PWM charge regulation, panel protection, battery charging management, dusktodawn floodlight control. Compatibility: VRLA, GEL, ironbased lithium battery chemistries supported. Performance: Designed to prevent overcharging and overdischarge while providing consistent light control behavior. Installation: Intended for integration into solar lighting systems where battery charging and automated floodlight control are required. Typical applications Garden and landscape floodlighting: Automatically switches lights on at dusk and off according to the set sensitivity or at sunrise, while protecting batteries from overcharge. Remote or offgrid security lighting: Keeps battery health managed through PWM charging and antiovercharge protection, ensuring dependable nighttime operation. Pathway or yard lighting with battery storage: Compatible with common battery types used in standalone solar lighting to provide reliable charge management and automated control. What it solves Eliminates worry about manual monitoring by providing automated dusktodawn control. Reduces risk of shortened battery life from overcharge or deep discharge. Protects the solar panel from adverse charging conditions with open circuit antiovercharge protection. Offers flexibility to work with different battery chemistries used in many solar lighting installations. Use this controller when you need straightforward battery charging management and automated light control for outdoor lighting systems that use VRLA, GEL, or ironbased lithium batteries.
