Trunk Wire Solutions
GameChange Energy’s Trunk Wire Solutions reduce connection points, streamline installation, and provide a flexible approach to utility-scale solar electrical infrastructure.
Designed for both fixed-tilt and tracker applications, the solution supports customized harness configurations while allowing customers to source the trunk wire separately. The result is a project-specific eBOS solution engineered to reduce complexity, control costs, and accelerate installation.
A More Efficient Approach to Solar Wiring
Traditional solar wiring architectures can require numerous connectors and connection points throughout the array. GameChange Energy’s Trunk Wire Solutions simplify the system by eliminating the need for PV connectors near the trunk and reducing connections across the installation.
With custom harness takeoffs engineered for the project layout, the solution can help crews install the system quickly and consistently while supporting both fixed-tilt and tracking topologies.

Key advantages
Reduced connection points and connectors
Faster field installation
Fuses positioned in free air
Custom harness takeoffs and system design
Flexibility to source the trunk wire
Configurations for fixed-tilt and tracker systems
Designed Around Your Project
Every solar project presents a different combination of module layout, electrical design, installation requirements, and field conditions. GameChange Energy can configure the harness takeoffs and branch connections around the needs of the site.
The system supports insulation-piercing or crimped branch connections, a wide range of PV connectors, and integration with multi-string harnesses. Inline fuses provide additional design flexibility within a streamlined eBOS architecture.
