1. process is benefit to battery full charging and its life span Battery state when the battery voltage is in normal condition the state LED lights in green state LED flashes slowly in green when battery finishes its charge When the voltage of the battery is lower it will get in yellow color When the voltage goes down continuously to over discharge the 4 12. Problems amp Troubleshooting Troubleshooting The charge LED indicator doesn t light in Check if the cable of solar panel connects properly green when sunlight gets the PV panel System over voltage or open circuit of the battery check if the battery connects to the system cable properly or the charging circuit damaged The load LED indicator light but there is no Check if the load connects to the system properly power output The charge LED indicator flash quickly The load LED indicator flash quickly and Check output circuit If the load short or over load there is no power output occurs remove the load and push the button and the controller will resume its work after 30 minutes The load LED indicator light slowly and Overload occurs remove some loads and push the there is no power output button again and the controller will resume its work after 30 minutes System state LED indicator flash in red Over discharge of the battery The controller will SOLAR POWER CONTROLLER SDPCxxA USER MANUAL Characteristics Control circuit use MCU and professional software as the control center to fulfill intelligent system control Charging mode use PWM high efficiency charging way Boost recovery and float charging auto work for battery long life Use temperature compensation High accuracy over discharging control by the discharging rate Over discharging control color and there is no power output resume its wo
3. d Disconnect the i Sa load at fault and press the button it will resume its work in 30 seconds or in another day BATTERY Work mode setting Installation Way of setting press the on amp off button for 5 seconds long until the number on the LED screen 203mm begins to flash Press the button to choose a proper number When the number no longer flashes the setting is completed Press the button to check the value Light ON Light OFF control mode The load will start working when it gets dark until it gets bright or to the end of a setting time There will be a 10 mins delay before turning on the load in order to make sure if it really gets dark Light ON set time delay OFF mode the start process same with above Load will be closed after the setting time Setting time can be seen in time setting table Common controller mode The controller will work as a common controller no light and time control no ON and OFF delay time only has the else function If no sunlight on PV panel it will a fix the controller in a certain place size of the installing hole 123mm Size 193 x83 mm Length between installing holes 203x123 mm b Prepare wire Choose the plastic Copper wire Current density no more than 4A mm Cut the suitable length of wire and make it as shout as possible Peel off 5mm the plastic at the end of wire turn on load at once If sunlight on PV panel it will turn off load at once c Connect the wire t
4. o the battery port on the controller to the battery Pay attention to the pole Test mode It used for the Light control system installed test Only cancel the ON and OFF delay of the connection If the pole is reverse it does not work It has the function of self protection and Light Time modes when the number displayed on the LED is from 1 to 15 it is in Direct output mode there is no any part will be damaged during this step but should correct this mistake Ten minutes after darkness falls the output switches on and remains on for the duration of the delay d Connect the wire to the PV port on the controller to PV panel If the connection is correct and the PV panel gets the sunlight charging indicator will be light e Connect the load to the load port on the controller Attention the pole should be correct selected 1 to 15 hour delays can be selected in increments of 1 hours Time settin Attention during the installation if the voltage of the system is 24V you can not use the 8 hands to touch any conductor in the system circuit in order to protect from electric shock Workmode 1D Workmode LED Workmode wD Using umon o uavonsonamatvom e imone nimavore gt Charge amp overpressure indication If the system is properly connected when sunlight shines on Ce ee voltage and keep 10 mins to activate battery lastly to float voltage and keep this state for the best ml taeda ae OT state of battery These
