Fault behaviour

Operating the solar charge controller is dangerous in the following situations:
The solar charge controller does not appear to function at all.
The solar charge controller or connected cables are visibly damaged.
Emission of smoke or fluid penetration.
When parts are loose.
In these cases immediately remove the solar charge controller from the solar panels and battery.

Function

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.
 Load is default setting ON.

LED INDICATOR

LED Illuminate green when solar panel is charging battery
PANEL LED off, PV voltage less than Battery voltage or solar input polarity is connected in wrong way, solar input is cut off.
LED Illuminate green, battery is good and voltage of battery is 12.5-13.6V;
BATTERY 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 Illuminate red, polarity of battery is connected in wrong way,
Question or the battery voltage is below 7.5V
Blink in red,




LED off
No abnormality detected
LED Illuminate white, system provide power to load in proper way;
Load 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.

Installation

Danger of explosion from sparking! Danger of electric shock!

The solar charge controller may only be connected to the local loads and the battery by trained
personnel and in accordance with the applicable regulations.

Follow the installation and operating instructions for all components of the PV system.

Ensure that no cables are damaged.

Ensure that polarities of Solar panel/battery/load are connected in proper way.
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
