Shoals’ Big Lead Assembly, or BLA for short, is an aboveground aluminum trunk system that combines the functionality of cable assemblies, combiner boxes, and fusing all into one, simplifying the wiring of your solar field. Using our latest in-line fuse and wire manufacturing technology, we offer you a site free of traditional DC string combiners. With the BLA, the entire load is combined into a single pair of aluminum conductors running from the sub-array to the inverter. The result is a system that can be installed for 43% less using 20% less material with 83% fewer points that need to be inspected and maintained over the life of the system. The entire system is plug-and-play, factory manufactured and quality guaranteed.
