40A Solar Charge Controller, 12V/24V Intelligent Regulator with LCD Screen and USB Port (40A)

【Intelligent Chip】: Industrial-grade main control chip, intelligent industrial-class main control chip, 16-level AD sampling accuracy, temperature, charging current, and precise real-time display of discharge current. 【Charging with Auto-Focus Tracking】: High charging efficiency, continuous detection during charging, bidirectional focus tracking. MPPT tracking efficiency can reach 99.9%. Charging efficiency is 15% to 20% higher than that of a general controller, and the circuit's energy conversion efficiency reaches 98%. 【Large Screen Intelligent Main Control Console】: Large LCD screen, adjustable charging and discharging parameters, ultra-wide adjustable charging range. As long as you understand the battery characteristics and set the corresponding charging parameters, you can charge any battery. Output power is disabled and adjustable, making it more convenient. 【Current Limiting Charging Mode】: When the panel's power is too high and the charging current exceeds the rated current, the controller automatically reduces the charging efficiency to operate at the rated current. Features a bidirectional anti-backflow circuit for mosquito tubes, high-power charging mode, and extremely low heat generation. 【A Variety of Protections】: Built-in overheating, overcurrent, short-circuit, open-circuit protection, and reverse connection protection. When a fault is cleared, the controller automatically recovers without damaging the device. Three-stage charging management effectively protects the battery.
