Pacakge including:
1. 1PCS 40A solar controller
2. 1PCS user manual 

This items is just for off-grid Solar PV system. 
For 12V PV system: 30V for Max input,480W Solar Panel. 
For 24V PV system :50V for Max input,960W Solar Panel.
Ideal for Seal lead acid battery,AGM,GEL Battery 
Danger of explosion due to improper handling of batteries!Corrosive hazard by leaking battery acid!

Kepp Children away from batteries and acid! Smoking,fire and naked lights are proibited when handling batteries.Prevent sparking and wear eye protection gear during installation.

Solar Modules generated power from light incidence.Even by low light incidence slolar modules carry the full voltage.Therefore,work cautiously and avoid sparking during all work.

System Indicator
1.Solar Indictor
off:without enough sun,charge off.
Fast flashing:Buck/equalize charge
Constant on:Acceptance charge
Slow Flashing:Float Charge
2.Battery indicator
Green: Battery Power is full
Orange:Battery power is middle
Red:Battery Power is low
Red Flashing:Battery over discharge
3.Consume indicator
Off:Controller ouput closed
ON:output normal
Slow flashing:Coninus over current
Fast Flahsing: Short Circuit

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 0-13 hours.

Lighting control Option
Press the setting button to activate the mode display,press the button for 3 seconds,and select the desired mode.
