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


Green Slowly flashing when battery level full

Yellow ON when battery level low

RED ON when loads cut off.


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


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


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


3.10 minutes off before the controller start

to work
