A combiner box houses the parallel connections that are necessary when multiple solar panels are used in a system. A combiner box also provides an easy access point for future panel additions and is typically located near or over the roof penetration. The weather tight strain reliefs used in the connections to the combiner boxes come with the SunRunner Panel Kits or can be purchased separately.
This C-box is for efficiently combining solar panel output cables and sealing off a roof penetration. Its rugged and spacious design make installation and trouble shooting very easy.
