NEW TEKTRUM 50A 12V/24V SOLAR PANEL CHARGE CONTROLLER WITH LCD DISPLAY

This Item Includes a Case of One (1) 50A 12v/24v Solar Charge Controller With LCD Display. 

Product Description This charge controller works with both 12v and 24v charging systems with automatically switching capability. The LCD screen updates the voltage of battery ,charging current and load current automatically every 5 seconds. The CPU (Central Processing Unit) inside the charge controller controls the high-efficiency PWM (Pulse Width Modulation) charging mode. The controller provides various protections such as over-charging, short circuit, overload, polarity, and thunder etc. for your charging system. The user-friendly LCD display menu allows you to set up and monitor your charging system in seconds.
