Main purpose and benefits This solar charge controller monitors solar panel output in real time and continuously tracks the peak voltage and current value V1 to charge batteries at the panels single power point. By matching charging to the available solar power, it helps maximize energy harvested from panels and maintain reliable battery charging. Key features Real time power detection and peak tracking: Detects solar panel voltage and current and locks on to the V1 value to enable near maximum power charging. LCD display and user controls: Clear LCD shows operating status and control parameters. Buttons allow viewing parameters and adjusting settings to match different system requirements. Dual fan cooling and current limiting: Dual fan cooling provides active thermal management. When charging current exceeds the rated limit, the controller automatically reduces charging power to prevent overload. Broad battery compatibility: Supports colloidal, sealed, open, and lithium battery types for flexible deployment across different systems. System compatibility: Intended for household photovoltaic systems, communications base stations, highway monitoring systems, and other off grid or backup power installations. How it solves common problems Increases usable solar output by tracking peak panel conditions and adapting charging to deliver higher power to the battery when available. Prevents charger overload and reduces thermal stress through automatic current limiting and dual fan cooling. Simplifies system setup and tuning with an LCD interface and adjustable control parameters to fit a variety of battery chemistries and system sizes. Typical applications Residential solar battery charging for daytime power harvesting and storage. Backup power and battery maintenance at communications base stations. Power supply and battery charging for highway monitoring stations and traffic cameras. Performance and operation notes Continuous monitoring of voltage and current enables adaptive charging behavior based on real operating conditions. Useradjustable parameters via the LCD allow the controller to be adapted to specific battery types and installation needs. This controller is designed to improve charging performance, protect system components from overcurrent, and provide flexible compatibility for multiple solar power applications.
