Product overview A programmable solar charge and discharge controller with a largescreen LCD for clear status display and easy adjustment of charging and discharging parameters. Designed for flexible use across multiple solar and battery setups, with builtin protections that recover automatically to safeguard the controller and maintain stable energy conversion. Key features Largescreen LCD display: easytoread status information and menu navigation for monitoring battery voltage, charging mode, and system status. Adjustable charging and discharging parameters: set voltages and modes to match system requirements and battery chemistry for safer, optimized charging. Broad battery compatibility: supports leadacid batteries, lithium iron phosphate batteries, and ternary lithium batteries, making it suitable for mixed installations and replacements. Wide application range: suitable for solar power generation systems, smart home energy storage, solar chargers, solar ventilation systems, solar light boxes, solar billboards, and solar warning lights. Comprehensive protection suite: builtin protection against overcurrent, short circuit, reverse connection, and open circuit. Protections restore automatically without damaging the controller. Improved conversion performance: automatic recovery and protection logic help maintain stable operation and improve overall energy conversion efficiency. Why choose this controller Solves common system setup problems by offering configurable parameters that match different battery types and system demands. Reduces downtime and maintenance with autorecovery protections that avoid permanent controller damage after faults. Provides clear, local monitoring with the large LCD so you can verify settings and system behavior without external tools. Simplifies integration into existing systems because it supports multiple battery chemistries and many solar applications. Practical use scenarios Residential offgrid system: Use the controller to manage charging for a home solar array and battery bank. Adjust charge cutoffs and discharge limits for the installed battery chemistry to extend battery life and maintain reliable backup power. Solarpowered outdoor signage: Control charging and discharging for solar billboards or light boxes. Builtin protections prevent damage from wiring errors and restore operation after transient faults, keeping displays lit reliably. Remote ventilation or warning systems: Power a solar ventilation fan or safety light with confidence. The controller handles different battery types and protects against short circuits and reverse connections common in field installations. What it does not assume No need to your batteries or controllers when switching battery chemistries, because parameters are adjustable to match leadacid, lithium iron phosphate, and ternary lithium batteries. Technical and performance notes Primary functions: charge regulation, discharge control, realtime display, and automatic fault protection and recovery. Performance focus: stability and protection to maximize usable power and reduce the risk of controller failure under common fault conditions. This controller provides a flexible, dependable way to manage solar charging and discharging across a variety of small to medium solar applications while protecting connected batteries and the controller itself.
