Pentair Technical Products introduces the Hoffman™ Solar Combiner Box, designed to meet the challenges of solar energy applications. The combiner box provides a simple solution for combining electrical inputs for photovoltaic applications into a single output, while offering robust protection against harsh environmental conditions and sufficient flexibility to keep pace with emerging demands.

The Hoffman Solar Combiner Box is available in POLYPRO™ and 14-gauge mild steel models. Non-metallic POLYPRO material is non-glass-filled polyester that offers a superior and cost-effective combination of corrosion, impact, chemical and UV resistance, and protects against wind and moisture. 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, oil-resistant gaskets and a Type 4 rating.

Both versions are available in 6- 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 for quick and easy changes. Mounting panels with silk-screened labeling facilitate simple mounting and reference. They can also be used with C11000 alloy copper, electroplated busbars for efficient power distribution.

"Solar energy is one of the fastest growing markets in the renewable energy industry," said Heidi Hung, Product Manager at Pentair Technical Products. "Hoffman Solar Combiner Boxes are ETL certified to UL 1741 and 600 VDC rated to deliver versatility and reliable operation in these harsh environments."
