Why Solar?
The energy we can use becomes less and less…
The SUN belong to everyone!
Why don’t we use it!

What is ISSL?
ISSL=Integrated Solar Street Light
It integrates solar panel , LED light,LiFePO4 battery and
a smart MPPT controller in one compact body.

4. www.hitechled.cn
How does ISSL work?
The solar panel converts sunlight into electricity and stored in Li-Fe battery via
controller, the LED light will work at night automatically under the light sensor
control, and provide light for the different areas. The LED light will be at low
power mode (about 30% of full power) normally when there is no motion but it
will be switched to full power mode when PIR sensor detects motion, the full
power mode will last about 30s (after the last motion detected) and after 30s it
will be switch back to low power mode until new motion detected . It can be also
pre-programmed by time schedule without motion sensor. Say 1st one hour @
20% illumination ,2nd 4hrs @ full brightness, the rest hours(before sun rise) @
30% illumination.
