Function: 1. High performance: Adopted a maximum power tracking algorithm to improve the system's energy utilization rate, and various tracking algorithms are integrated to quickly locate the best operating point of the IV curve. Faster response speed and higher tracking efficiency. 2. Comprehensive protection: with battery reverse connection protection, PV reverse connection protection, PV short circuit protection, charging overcurrent protection and other multiple protections. It supports Modbus protocol to meet the communication requirements of a variety of environments. 3. Current Limited Mode: Provide the current limited charge mode. When the solar panel power is too large and the charging current is higher than the rated value, the controller will automatically reduce the charging power to keep the solar panel operating under the rated charging current. 4. Safety: Built-in temperature compensation, lowered charging, no fan, can work safely in extreme temperatures. The LCD screen can check the operating data and status of the machine. 5. Universal: The solar charger controller supports lithium battery, gel battery and other batteries, suitable for home power generation, base station, RV, yacht, ship and other solar PV system.
