Wide Compatibility: The solar charger controller with a 30A rated discharge current automatically supports 12V or 24V systems, compatible with lead-acid batteries including OPEN, AGM, and GEL. Dual USB 5V/3A output ports allow charging of mobile phones, tablet PCs, and other devices requiring 5V input.Multiple Intelligent Protections: Built-in overcurrent protection, short circuit protection, reverse connection protection, and open circuit protection. All protections feature automatic recovery, ensuring no damage to the controller and providing reliable device safety.Functional LCD Screen: Easy to install and operate, featuring an intuitive LCD display that clearly shows system status and data. Supports mode switching and parameter configuration. Adjustable low-voltage disconnect levels help prevent battery over-discharge, ideal for home, industrial, and commercial applications.3-Stage PWM Charging Control: Utilizes a full three-stage PWM charging method—bulk, boost, and float—to enable efficient, fast, and intelligent charging. This helps maximize battery efficiency and extend battery lifespan.Easy to Use: Connect the battery first, then the solar panel, followed by the load. Simple one-button operation allows easy adjustment of settings.Specifications: - Rated Voltage: 12V/24V - Charge Current: 30A - Discharge Current: 10A - Max. PV Voltage: 50V - Max Solar Input: 50V
