TriStars help control solar-powered railroad wayside signaling applications, such as this intermediate signal. Three 20-foot towers make up the system and each retractable tower holds 1,120W with two TriStar MPPT 45 units (each regulating 580W).

EMI exclusively manufactures each tower for Ameresco Solar. The systems are shipped complete and assembled in the field. On-site training and audits ensure proper operation. Currently, Ameresco Solar has several hundred of these systems installed in North America on all Class I railroads.
