12V 24V 30A Automatic Solar Controller BX3, R27

DescriptionThis is an Automatic Solar Controller which is meant for off-grid solar systems, especially solar light systems and protects the battery from being over charged by the solar module and over discharged by the loads. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.FeaturesCharge for 12V lead acid batteryHigh efficient, energy-saving, safeLight Control With Time Delay4-Stage charge with PWM outputSpecificationsDisplay: LCD liquid crystal displaySize: 133.5*70*35mmFloat voltage: 13.7V(default value,adjustable)Discharge cut-off voltage: 10.7V(default value,adjustable)Discharge recovery voltage: 12.6V(default value,adjustable)USB output: 5V/2AStandby current: <10mAWorking temperature: -35~ 60℃Weight: 165g Getting along with the Solar ControllerConnection proceduresThe connection should be carried out carefully following the preset procedures in order to avoid damaging the battery or the Controller as stated in the following picture:   As labelled on the controller the polarities should never be reversed. Otherwise the battery could be caused short-circuit. Below is the description of the right connections and possible signs from the controller that can hint the user in any situation going on with controller or the battery.     And here is the the way to deal with the controller through its controls      It can also supply different appliances including AC loads simultaneously as shown below:
