#Charging

Auto-charging during the day

First, the solar charge controller will turn off LED lights towards dawn once solar panel voltage rise to 5v, which is accounted for a little sunlight in the morning.

When there is enough sunshine during the day, the solar panel will work together with the solar charge controller to collect the solar energy.

Commonly, in a 12v solar system, with the effect of insolation, the voltage of its solar panel will rise to around 18v so as to charge the 12v battery bank. Meanwhile, the solar charge controller will prevent overcharge to protect the batteries.

#Discharging

LED turns on automatically at night

When there is not enough sunlight towards dusk and solar panel voltage drops to a value under 5v, the LEDs will be turned on accordingly.

“Time control mode” and “Motion sensor control mode” will be working during discharging at night.

As primary function, Time control is used to customize different brightness in different time slots. For example:

  • Time slot 1: 6:00 pm – 7:00 pm, 50% brightness
  • Time slot 2: 7:00 pm – 8:00 pm, 70% brightness
  • Time slot 3: 8:00 pm – 10:00 pm, 100% brightness
  • Time slot 4: 11:00 pm – 2:00 am, 50% brightness
  • Time slot 5: 3:00 am – 5:00 am, 30% brightness

And so on.

Motion sensor function

Motion sensor function

a motion sensor is used as a minor function which can be recognized as an energy-saving mode

The LEDs’ brightness will rise to 100% when someone is approaching the lights and then revert to the previous level of brightness 20 seconds after the man leaves.
