Features: 1.Build-in industrial micro controller. 2. Big LCD display all adjustable controlling parameter of the system. 3.Fully 4-stage PWM charge management. 4.Build-in all necessory protections including short-circuit protection open-circuit protection reverse protection over-load protection. 5.Dual mosfet Reverse current protection low heat production LCD display/key and Operations: MENU:Switch between different display or to enter/exit setting by long press. UP: Press to increase value. DOWN:Press to decrease value. System Connection: 1.Connect the battery to the charge regulator - plus and minus. 2.Connect the photovoltaic module to the regulator - plus and minus. 3.Connect the consumer to the charge regulator - plus and minus. The reverse order applies when deinstalling! An improper sequence order can damage the controller! Attention: 1.press the [Down] button to ON/OFF load manully at main display. 2.the work mode is working as below: [24H] load output 24hours [1-23H] load on after sunset and closed after setting hours [0H] Dusk to dawn 3.Batteries:Only fit for OPEN AGM GEL 4.The charge regulator is only suitable for regulating solar modules Never connect another charging source to the charge regulator. 5.Please make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
