- LCD Crystal Display: The solar charge controller has a large LCD display that clearly shows the battery status, solar panel status, mode control, load output status, and parameter values for easy monitoring. - 7 Working Modes: This controller supports seven modes including charging mode, light control mode, light control plus time delay control mode, general control mode, manual control mode, time control mode, and a factory use test mode. - Automatic detection of 4 voltage types: It can automatically detect DC12V, DC24V, DC36V and DC48V, making it compatible with various battery systems. - Large cable connection: With large terminal connections and generous spacing, it accommodates 16mm cables, enabling easy installation and reducing losses from current and voltage drop. Use scenarios - Off-grid outdoor lighting: Pair with LED lights and solar panels to run dusk-to-dawn lighting or use the time delay option to customize operating hours, with automatic status monitoring on the LCD. - Remote cabin or workshop power: Manage battery charging from solar panels using charging mode, while selecting general or manual control to fit daily routines and load requirements. - RV, boat, or other 12/24/36/48V installations: The auto voltage detection simplifies setup across different vehicle or marine battery systems, ensuring compatible operation without manual reconfiguration.
