Welcome to our store! 1. High Performance: Utilizes an industrial-grade main control chip and high-quality components to enhance system performance, achieving up to 98% conversion efficiency and ultra-fast tracking speed for optimal tracking efficiency. The controller features automatic 12V/24V system identification, compatible with both 12V and 24V systems. 2. LCD Display: The controller boasts a large LCD display with adjustable charging and discharging parameters. It includes a power-off memory function, clearly displays status and data, and allows for easy switching between modes and parameter configurations. Suitable for home, industrial, and commercial use. 3. Multiple Protection Functions: The controller's complete 3-stage charge management improves system efficiency and extends battery life. Built-in multiple protection functions include overcurrent, short-circuit protection, open-circuit protection, and reverse connection protection, all of which are self-repairing and will not damage the controller. 4. Input and Output: The controller features dual USB outputs with a maximum current of up to 25A, supporting mobile phone charging. It uses dual MOS anti-backflow circuits with ultra-low heat. The controller will heat up during operation, so ensure it is installed in a flat, well-ventilated location. 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.
