The Magnum MLT4000S Solar Hybrid Light Tower is a solar-powered and propane-fueled unit developed in cooperation with the Propane Education & Research Council.
An LP-fueled back-up generator keeps its batteries charged in all conditions, according to Magnum. Because the light tower does not consume diesel fuel, it’s less expensive to operate and produces fewer greenhouse gas emissions. In addition, propane does not degrade over time and emits fewer carbon dioxide emissions and toxic pollutants. During the day, a solar-panel array charges the light tower’s batteries for nighttime operation. If cloudy or inclement weather prevents the batteries from fully charging, a propane-fueled, air-cooled Generac generator turns on automatically and recharges the batteries.
