This compact solar controller uses Pulse Width Modulation (PWM) to manage battery charging from a connected solar panel. It features light and timer control, similar to street lights, and three charging states (bulk, equalise, and float charging). It provides all the important safety features such as overcharge, over-discharge, over-current, short-circuit, and reverse-polarity protection. Red charge LED indicator Green power LED indicator Hang hook Battery voltage automatic identification PWM charging mode Comprehensive electronic protection Specifications: Rated Voltage: 12V Strong Charging Pressure: 14.8V Equilibrium Charging: 14.5V Float Charging Pressure: 13.7V Under Voltage: 10.8V Under Recover Voltage: 13V Non-Load Current: ?6mA Charging Circuit Voltage drop: ?0.2V Discharge Circuit Voltage drop: ?0.1V
