Intelligent solar controller board designed for reliable automated outdoor lighting Why this controller helps Automates charging and lighting so outdoor lights operate without daily manual intervention. The board recharges batteries by day and switches lamps on at night, delivering consistent performance for garden, pathway, and landscape lighting. Works with a wide range of battery types and voltages, so it can be reused across different solar lamp designs and projects. Built to protect connected components from common electrical issues with a compact form factor that fits inside most lamp housings. Key benefits Reliable automatic operation: Daytime charging and nighttime switching are handled automatically by the illumination sensing function, reducing maintenance and user interaction. Broad battery compatibility: Supports 3.7 V to 24 V lithium and lithium iron batteries, allowing flexible use with small wall lamps up to larger landscape fixtures. Surge protection and recovery: 1.1 A output current with an automatic recovery circuit breaker prevents damage from overcurrent events and restores normal function once conditions to safe levels. Durable construction and compact size: Glass fiber board material offers stable operation across outdoor lighting applications while the compact design installs easily within typical solar lamp housings. Flexible control modes: Offers both illumination control and nonillumination control options, defaulting to automatic illumination sensing. A singlechip microprocessor enables multiple control functions in minimal space. Features at a glance Function: Automatic daytime charging and nighttime lighting control Compatibility: 3.7 V to 24 V lithium and lithium iron batteries Output: 1.1 A with automatic recovery circuit breaker Material: Glass fiber printed circuit board Control: Illumination control and nonillumination control modes, default autosensing Size: Compact form factor suitable for most solar lamp enclosures Electronics: Singlechip microprocessor for multifunction control Practical applications Solar lawn lamp retrofit: or upgrade the controller in walkway or lawn lamps to restore automatic day/night operation and improve battery compatibility. Garden and landscape lighting: Use in distributed landscape fixtures powered by different battery packs to standardize control behavior across a property. Wall or porch solar lights: Install inside compact wall lamp housings where space is limited but reliable automatic switching and overcurrent protection are required. This controller provides dependable, compact, and versatile control for a wide range of solar outdoor lighting projects without added complexity.
