COMBINER BOX
product line
The next evolution of combiner boxes, optimizing both cost and layout without sacrificing quality or performance. The new SlimLine® combiner box series from Shoals provides both a lighter weight and more compact design than ever before.
ultra slimline series
This is our most compact series of DC string combiners, but still allows plenty of elbow room for landing wire in the box and meeting NEC requirements for wire bending space for parallel 500MCM outputs.
