1500Vdc Solar Combiner Boxes for Utility-Scale Installations

Power management company Eaton today announced the release of its new Crouse-Hinds® series 1500Vdc combiner boxes for large-scale solar photovoltaic applications. The combiner boxes are designed to help customers reduce system costs by reducing wiring requirements and installation time.

“As GTM research noted earlier this year, overall project costs can be reduced by three to five percent by moving to 1500Vdc systems,” said Tony Gulrajani, solar marketing manager at Eaton. “Our combiner box technology and other electrical balance of system solutions are supporting this trend by helping customers reduce installation time and use fewer components.”

Designed for 1500Vdc systems, the combiner boxes help facilitate longer strings, fewer connection points, reduced labor and lower installed costs. For application flexibility, the Eaton solar combiner boxes are available with or without integral dc disconnect switches, up to 24 input circuits and a 15-Amp fuse size. The combiner boxes are also available with NEMA 4X, 4 and 3R enclosures for robust environmental protection. Additional customized options are available to meet specific application requirements.

Eaton engineered its 1500Vdc combiner boxes for greater heat dissipation to help support performance in the harshest of environmental conditions. The combiner boxes are rated up to 1500Vdc for continuous operation, meet Underwriters Laboratories (UL) 1741 standards for grid connection, and are Interek (ETL) listed for reliable performance.
