Welcome to our store! 1. High Performance: Utilizes an industrial main control chip and high-quality components for enhanced system performance, achieving up to 98% conversion efficiency with ultra-fast tracking speed. The regulator automatically identifies 12V/24V systems and is compatible with both. 2. LCD Display: Features a large LCD display with adjustable charging and discharging parameters. The power-off memory function clearly shows status and data, allowing for easy switching of modes and parameter configurations. Suitable for home, industrial, and business use. 3. Multiple Protection Features: The regulator's complete 3-stage charge management improves system efficiency and extends battery life. Built-in protections include overcurrent, short circuit, open circuit, and reverse connection protection, all with self-repairing capabilities that won't damage the regulator. 4. Input and Output: Equipped with dual USB outputs, the regulator supports mobile phone charging with a maximum current of 25A. It uses dual MOS anti-backflow circuits with ultra-low heat. The regulator will heat up during operation, so ensure it's installed in a flat, well-ventilated area. 5. Easy to Install and Use: Connect the charge controller to the battery first, then the solar panel, and finally the load. The disassembly sequence is the reverse of the wiring sequence.
