High Adaptation: Working Temperature: -35C to 60C, battery voltage: 12V/24V auto-sensing, charging current: 30A, discharge current: 10A. USB output voltage: 5V/3A, intelligent three-stage PWM charging, high efficiency. Safety Protection: Double MOS anti-backflow protection, low heat generation and low failure rate. It can implement built-in overcurrent protection, short circuit protection, open circuit protection, reverse connection protection, self-healing, without damaging the controller Perfect Design: The solar charge controller features a large LCD display, status and data are clear at a glance, and full three-stage PWM charge management. It adopts industrial-grade master control chip, high-quality materials, environmentally friendly, and high utilization efficiency. Wide Usage: Suitable for home, commercial, industrial, etc. applications, such as solar power generation systems, solar ad boxes, smart homes, smart irrigation, etc. Note: In order to ensure battery life and safety, the controller should be connected to the battery first, then to the charging device, and finally to the solar panel.
