Key benefits Protects your system automatically: built-in over-current, short-circuit, no-load and reverse-polarity protection are all self-recovering, preventing damage to the controller and reducing downtime. Clear, real-time monitoring: large LCD clearly shows charging and discharging currents and lets you query cumulative energy generated and total discharge quantity so you always know system status and history. Smarter battery care: complete 3-stage charging management and adjustable charge/discharge parameters extend battery life and improve performance. Convenient, reliable operation: temperature display plus light-control and delay control features help optimize charging for environmental conditions, and power-off memory preserves settings after interruptions. Main functions and performance Protection suite: automatic self-recovery from over-current, short circuit, no-load and reverse polarity events—protects both the controller and connected batteries without manual reset. Monitoring and logging: large-screen LCD displays instant charging/discharging current and provides cumulative generation and discharge readouts for simple performance tracking. Charging control: complete 3-stage charging management (bulk, absorption, float) with adjustable parameters to match battery type and application needs. Environmental and timing control: temperature display, light control and delay control let you tailor charge/discharge behavior to temperature and daily light cycles. Usability features: adjustable charging/discharging parameters and power-off memory keep your preferred settings and system behavior intact after power interruptions. Compatibility and installation Designed to work with standard battery-based controller systems and a wide range of battery setups where 3-stage charging and the listed protections are required. Suitable for typical controller installations; settings are adjustable to match system requirements without needing extra hardware. Practical use scenarios Small off-grid solar home: monitor daily generation, set appropriate 3-stage charging parameters to prolong battery life, and rely on self-recovering protections to minimize service calls. Mobile applications (RV or boat): view charging/discharging current on the large LCD, use delay and light-control for shore/generator transitions, and keep settings with power-off memory during travel. Remote backup or telecom sites: track cumulative energy and discharge totals, use temperature-aware control to protect batteries in variable climates, and depend on automatic recovery from faults to maintain uptime. Why this product stands out Combines comprehensive automatic protection with clear, actionable monitoring. Enables precise battery management through 3-stage charging and adjustable parameters. Reduces maintenance and downtime with self-recovering protections and power-off memory. What you get Integrated safety features, a large LCD for current and cumulative energy readouts, temperature and light/delay controls, adjustable charge/discharge settings, power-off memory, and full 3-stage charging management — all designed to protect the controller and optimize battery performance.
