Product Description
Solar Charge Controller
Multi-Functional/Safe/Smart
This solar charge controller utilizes an intelligent MCU control chip and features a high-definition LCD display that shows key parameters in real time, including battery voltage, charging current, load current, and ambient temperature. It supports automatic recognition of 12V/24V systems and incorporates multiple protection features including overcharge, over-discharge, overload, short circuit, and reverse connection protection. Dual USB ports enable direct charging for mobile phones, tablets, and other devices. Additionally, it supports external temperature sensors and remote control, making it suitable for residential solar power systems, outdoor photovoltaic energy storage, RV/camping photovoltaic power supply, and other scenarios. Installation is convenient, and operation is stable.
