Morningstar SunLight Controller SL-20L-12V

The Morningstar SunLight Controller is a high-reliability solar lighting and charge controller designed specifically for 12 V systems with up to 20 A load and solar input. The Morningstar SunLight Controller integrates PWM battery charging and advanced, microcontroller-managed lighting timer functions in a single rugged unit. The Morningstar SunLight Controller delivers ten selectable lighting control options—including fixed ON durations, ON/OFF/ON sequences and dusk-to-dawn operation—to optimise energy use and extend battery service life. Built for demanding environments, the Morningstar SunLight Controller features an anodised aluminium case, epoxy encapsulation and marine-rated terminals to thrive outdoors and in coastal or industrial installations. Benefits include precise lighting control, automatic night detection based on the PV array, temperature compensation, sealed or flooded battery compatibility, and built-in low-voltage load disconnect protection. Ideal for solar street lights, pathway illumination, signage, remote monitoring systems and off-grid load-driven applications, the Morningstar SunLight Controller ensures efficient solar system performance, minimal maintenance and long-term reliability.
