“As GTM research noted earlier this year, overall project costs can be reduced by three to five percent by moving to 1500 volt-DC 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 1500v DC 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 ampere (A) fuse size. The combiner boxes are also available with National Electrical Manufacturers Association (NEMA) 4X, 4 and 3R enclosures for robust environmental protection. Additional customized options are available to meet specific application requirements.
Eaton engineered its 1500v DC combiner boxes for greater heat dissipation to help support performance in the harshest of environmental conditions. The combiner boxes are rated up to 1500v DC for continuous operation, meet Underwriters Laboratories (UL) 1741 standards for grid connection, and are Interek (ETL) listed for reliable performance.
