SolaDeck models are flashed, seamless, weather-tight enclosures that are NEMA 3R rated. They provide a flashed roof penetration that connects the outdoor system wiring to the interior house wiring and give consistency in every installation. The 0799-2B Photovoltaic Combiner Enclosure is listed and labeled to UL 1741 standards and can be used to combine or pass-through wiring of both AC and DC circuits. A professional appearance is provided by the 18-gauge galvanized 90 steel and powder-coated finish.
