Homeruns, Interconnection & Extensions

For customers looking to route harnesses directly from the field to a combiner box, we provide both wiring harnesses and combiners, essential components in homerun applications.

At Shoals, all measuring, cutting, and terminations are completed in our factory before the product ever reaches the site. The result is pre-terminated wire that arrives ready for plug-and-play installation, reducing field labor and minimizing quality risks. Each cable is site-specific, factory-tested, and built to customer specifications, ensuring accuracy, repeatability, and a smoother installation process.

Shoals’ power distribution solutions reduce the need for specialized labor during installation, making solar integration simpler and more efficient. For end-of-row collection on sites where multiple trackers are stacked into longer rows, the use of larger copper conductors can significantly increase project costs. With SuperHarness and its optimized combination of copper and aluminum conductors, both […]

A method of combining multiple wires without the need for in-field splice. This patented device helps increase efficiency on site while reducing the amount of wire and number of combiner boxes needed.  With harnesses custom manufactured for your specific site, both labor and material costs are significantly reduced. The simplified design and robust construction also […]

Whip: A method of connecting a terminal to a connector. A typical use would be from a combiner box to a string of panels.  Jumper: A method of connecting two components with connectors. A typical use would be connecting strings between two rows or connecting a string to a Shoals combiner box with pre-installed pigtails. 

Shoals’ Parallel Harness, a key component of our Interconnect System™, is engineered to simplify installation and cut material costs. By including an inline fuse, it enables string pre-combination in the field, reducing the number of DC combiner boxes needed and maximizing fuse holder current ratings. Our harness is available in multiple configurations for bifacial and […]

Engineered custom harnesses specifically for First Solar modules, featuring inline fuses for optimized circuit protection.​ Available for First Solar Series 4, 6, and 7 modules, as well as bi-facial and crystalline panels, ensuring seamless integration across multiple PV technologies. ​Shoals™ patented Interconnect System™ reduces the specialized labor required in your installation, making the integration of […]

A wiring solution for unobstructed row solar sites, providing reliable power over long distances to the combiner or DC trunk bus (BLA) in stacked tracker configurations. SuperJumper is a next-level alternative to traditional 100% copper jumper wires used in long row applications with combiners. It integratesthe simplicity of copper home run installation with the cost-efficiency […]
