Solar Max Highway Advisory Radio ▰ ▰ ▰


SolarMax | Highway advisory Radio for Work Zones


The SolarMax Portable HAR System keeps traffic flowing by broadcasting up-to-the-minute radio advisories to motorists. The flexibility of the SolarMax System allows for quick 10 minute or less set-ups. Solar charged power offers dependable service around the clock and during extended periods of inclement weather.

The SolarMax System utilizes low power AM radio to inform motorists of conditions ahead, giving them enough time to take action or alternate routes. The SolarMax System can be used to assist in managing a construction site, a temporary incident, an inclement weather evacuation, or a frequently congested traffic area.

Messages can be changed quickly and remotely should conditions vary, and when the job is finished, the SolarMax System can be ready for duty on the next upcoming project.
