This NEMA 3R enclosure is made from 18 gauge galvanized steel with a powder coated finish provides a professional look. It has a dual ground lug, a 6 inch (150mm) universal DIN rail to mount fuse holders or terminal blocks. There are three roof deck knockouts 1/2", 3/4" and 1", and dimples to center a punch or drill for entry conduit or fittings. It has built-in flashing to seal to roof. It is only 2.5" deep and can fit under the array. To make pass-through connections inside the SolaDeck use one or more 2-String Pass-Thru Kits. This kit has 4 DIN mount terminals that can be used with AWG 6-16 wire, and hardware to hold them in place. Each terminal is 10mm wide.
For combining circuits use up to four DIN mount fuse holders, each 18mm wide, a positive and negative busbar and a 2-string pass thru kit to combine up to 4 module strings. Or use the two position positive and negative busbars for combining two strings, with or without fuses. Fuses are not included so order the appropriate fuses. It is ETL listed to UL STD1741 for photovoltaic combiner enclosures.
