Pentair Technical Products has released the Hoffman solar combiner box. According to the company, the product is designed to provide a simple solution for combining electrical inputs for photovoltaic applications into a single output, while offering protection against harsh environmental conditions.
The combiner box is available in POLYPRO and 14-gauge mild steel models. Non-metallic POLYPRO material is non-glass-filled polyester that provides resistance to corrosion, impacts, chemicals and UV rays, the company says. POLYPRO boxes provide an overlapping tongue-and-groove raised cover and gasket for a secure seal and are Type 4X rated. Mild steel models offer a cost-effective option with continuous hinges and oil-resistant gaskets, Pentair adds.
Both versions are available in six- and 12-string configurations and can accommodate a wide range of solar panel applications. Combiner boxes include touch-safe fuse holders, with a non-load break rating to 30 amps max. Mounting panels with silk-screened labeling facilitate simple mounting and reference, Pentair says.
