Thirty SunLight controllers used for solar street lighting at the newly constructed harbor city of Jinhae. Lighting control was set to turn lights on at dusk and off at dawn. Morningstar’s SunLight controllers were deployed because of their high quality reputation in harsh environments, and their easily adjustable PV-based lighting control settings. Sunlight controllers are available in 4 different models with 10 or 20 amp charge ratings that support 12 or 24 Volt battery systems. Photo courtesy of Lightron Lighting & Advancement.
