As larger system sizes have become more popular, heavier gauge wire harnesses are needed to go from the roof to the charge controllers. Our sturdily constructed roof mount combiner box uses two large bus bars that will easily handle everything from 10 ga. up to 1/0 cable. This combiner box comes with four standard, molded in, 1/2" knock-outs and room to drill out four more if needed. If you would like AM Solar to pre-drill extra holes please let us know when you place your order. The easily accessible spacious design and securely sealing lid make this the combiner box of choice for our installers.
Dimensions: 7-3/8" x 5-3/8" x 2”

3M VHB tape is used to secure mounting feet and combiner boxes to fiberglass or metal roofs (not rubber). Cut each 5" strip in half for each of four mounting feet per panel.
Ideal for Airstream roofs, Sikaflex protects the VHB tape from the elements. Use it to seal around mount feet, cable management hardware and combiner boxes attached to roofs. Do not use Sikaflex on TPO roofs.
