LED indicator:
Solar Panel LED:
Green ON when solar is charging Battery.
Green blink when the syetem over voltage
Battery LED:
Green ON when battery level in the right range
Green Slowly flashing when battery level full
Yellow ON when battery level low
RED ON when loads cut off.
LOAD LED:
RED ON when the output is on
RED slowly flashing when it`s over load
(the load amps is 1.24 times of rated current for 60 seconds,or the load amps is 1.5 times of rated current for 5 seconds.)
RED blink when the load is short -circuit.

This controller has Light and Timer control Function
Light control:When daylight starts to occur then the light source goes off. Meanwhile the Solar Panels will charge the batteries. when there is no sunlight the garden light will switch on.
Time control:There is an eight hours time control,that means it will go off when the Lights automatically switch off after 0-15 hours.

Lighting control Option
1.Press the power switch for 5 seconds and select the desired LIGHTING CONTROL option.The LED is on,which confirmed you have selected the right one.
2.The controller requires 10 munites of countinuous transiton values before it starts to work.These constraints avoid false transitions due to lighting or dark storm clouds.
3.10 minutes off before the controller start to work
