Solar Wireless Traffic Light Controllers

Cable-free control for temporary and solar-powered signal projects

A solar wireless traffic light controller can reduce trenching and simplify deployment where a conventional cable network is impractical. It is used for temporary traffic management, work zones, pedestrian crossings, remote junctions and projects that need controllers to exchange timing or synchronization information without a long control cable.

Start with the operating plan: identify the number of approaches and phases, the signal-head load, expected operating voltage, daily solar resource, battery autonomy, radio distance, line-of-sight obstacles and whether the system needs a master-and-slave arrangement. Output capacity matters as much as wireless communication. A configuration sized only for the current heads can become restrictive when a countdown display, pedestrian unit or extra phase is added later.

Solar wireless controller configuration checklist

For an accurate technical review, prepare the project information below before choosing a controller. These items describe what to confirm, not pre-set specifications for every model.

• Site and operating plan: location, approach layout, phase sequence, daily operating hours and any temporary or work-zone restriction.
• Signal and power schedule: signal-head type and quantity, required outputs, voltage, expected load, solar resource and storage requirement.
• Wireless arrangement: distance between units, line-of-sight obstacles, synchronization requirement and master-and-slave or other project control arrangement.
• Delivery review: mounting or trailer arrangement, wiring diagram required for the selected system, destination and requested delivery date.

Use the solar traffic signal controller system-design guide, the solar autonomy test-log template and the portable work-zone traffic signal guide to organise the project information.

For a useful quotation, share the site layout, required operating hours, head schedule, distance between units, signal sequence, quantity and destination.
