Description

The solar-LED streetlight controller is made up of

one 80 W battery charger and one 25 W LED

driver.

When the sun is present the charger converts the

electricity from the solar panel then charges the

battery. In a dark ambient where no sun is present

the battery powers on the LED lamp as a

streetlight. When wet or cloudy weather persists

for several days the battery gradually runs out of

power. The controller then switches on the AC

mains supply instead of the battery to power on

the LED until the battery is fully charged again.
