This industrial-grade LCD solar charge controller offers superior performance and reliability. Key Features: Industrial-grade main control chip: High-quality components ensure 98% peak conversion efficiency, ultra-fast tracking speed, and efficient power management. Automatically identifies 12V/24V systems. Large LCD screen: Adjustable charging and discharging parameters with power-off memory. Clearly displays system status and data, allowing easy mode switching and parameter configuration. Suitable for home, industrial, and commercial use. Multiple protection features: Built-in overcurrent, short-circuit, open-circuit, and reverse connection protection. All protections are self-healing and won't damage the controller. Advanced charging management: Complete 3-stage charging management improves system efficiency and extends battery life. Dual USB output with a maximum current of 25A supports mobile phone charging. Efficient cooling: Dual MOS anti-backflow circuit ensures ultra-low heat generation. Install the controller on a flat, well-ventilated surface. Easy installation and use: Connect the controller to the battery first, then the solar panel, and finally the load. Disassembly is the reverse of this sequence.
