Solar Enclosures
Hoffman CUF Series Solar Commercial Transition Boxes, also known as pass through boxes, provide a convenient location for transitioning wires in a commercial array when fusing is not required. The enclosure is made of fiberglass and the number of circuit input pairs is 4 to 20 with wire size input and output of #24 - #3 AWG.
Hoffman Residential Transition Boxes enable installers to combine and/or transition strings to conduit, reducing costs by enabling users to switch to standard building wire and simplifying connections in the enclosure. It provides a touch-safe and secure means to transition strings. The low profile enclosure is designed to be mounted adjacent to the array using racking system accessories or beneath the array using the optional box bracket accessory.
Hoffman The RJ Rooftop Junction Boxes with flashing provides a safe, secure, and NEMA 4X watertight solution for the solar installer to penetrate the roof for attic runs and make the proper wire connections. The junction box provides a higher level of protection for the point of penetration in the roof as well as the electrical connections inside.
Hoffman RF Solar Combiner Boxes support the combination of up to 3, 4, 6, 8 or 12 strings. RF-3, 4, 6 are ungrounded while RF-8 and 12 are grounded. In ungrounded combiner boxes, fuses are provided for both the positives and negatives. The combiner boxes are made of fiberglass, offering protection against exterior elements. The oversized busbars reduce losses and offer improved efficiency for connections.
