Magnum’s MLT4000S Solar Hybrid Portable Light Tower

Developed in cooperation with the Propane Education & Research Council (PERC), Magnum’s MLT4000S Solar Hybrid Light tower offers a greener, more efficient way to illuminate construction jobsites. 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-powered Generac generator turns on automatically and recharges the batteries until the solar panels can take over.
Unlike diesel, propane does not degrade over time, reducing fuel-related performance problems. Propane also emits fewer carbon dioxide emissions and toxic pollutants than diesel, improving air quality and worker safety on the jobsite. PERC is offering buyers a $3,500 incentive to purchase the MLT4000S through its Propane Heat & Power Incentive Program. Here are the specs:
