The solar system controller is designed to: Monitor the state of charge of the battery; Controls the charging process, Control the connection/disconnection of loads, Make sure solar system works at proper condition.  Manual load switch with automatic re-start. 




Illuminate green when solar panel is charging battery
 LED off, PV voltage less than Battery voltage or solar input polarity is connected in wrong way, solar input is cut off.
Illuminate green, battery is good and voltage of battery is 12.5-13.6V;
 Blink in green, battery is fully charge and in float charging mode, voltage of battery is 13.6-14.4V. Illuminate orange, battery is weak, voltage of battery is 11.5-12.5V Illuminate red, battery is empty, voltage of battery is below 11.5V
LED Question
Illuminate red, polarity of battery is connected in wrong way, or the battery voltage is below 7.5V
Blink in red,  Battery is over discharged, can't be charged again.
  Voltage of battery is higher than 14.4V or battery is broken, can’t be charged
  If battery is over current charged(>10Amp) more than 3 second, controller will cut off input of battery and
 Red LED blink 3 minutes than Red LED turn off
  Over voltage of solar panel
 LED off
 No abnormality detected
LED Load
Illuminate white, system provide power to load in proper way;
 Blink in white, overload, more than 10Amp, last 3 second, controller will cut off output automatically. After 30 seconds blink, LED will turn off. LED off, no output of load.
