Build DC cable assemblies and combiner boxes to the string diagram, with every lot recorded.

A solar array is wired with hundreds of short parts that all look alike. Operators cut, crimp and label them at a bench before they reach a roof or a field. A cable cut to the wrong length or a connector crimped on the wrong gauge stays hidden. Nobody sees it until a string is energised. Replacing one faulty assembly on a roof means a second visit with a ladder, a new part and a crew who were meant to be somewhere else. Build it at the bench.

Production software for component makers ties each assembly to its string diagram, cable reel and tested result. Combiner boxes carry fuse ratings, surge device lots and a test sheet. Tell us how your combiner boxes and cable assemblies move between benches, and the order flow follows that route.

A project engineer sends a string diagram listing cable lengths, connector types, fuse ratings and isolator positions. The planner turns that diagram into a cable cutting list plus a bill of materials for the box. Stores issue cable reels by lot. Next come connectors, glands, fuses, DIN rail, busbar and an enclosure for each box on the order.

Operators cut and strip cable, crimp connectors with a calibrated tool and pull-test samples. Quick work. Combiner boxes are wired and labelled. Continuity and insulation are checked. Finished assemblies are bundled by string, tagged and packed in cartons with the label and the test sheet for that site’s order. The crew then matches them to the diagram.
