Product overview

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.
