PSDC Power Centers
Indoor enclosure designed to mount directly on the DC end of one or two SW or DR inverter/chargers. Eliminates the need for additional conduit boxes & offset conduit fittings and cramped wiring space. Includes mounting provisions for up to ten small (0.75” wide) or four large (1.5” wide) DC breakers (medium and large breakers use a common space and can be mixed). Includes knockouts for C-series controllers or RVPP Solar Boost controllers on top of the enclosure. 

Enclosure size: 32.5”H x 16”W x 9”D, shipping: 12.75” x 36” x 19.5”, weight: 38 lbs.
Both the PSDC-175 and PSDC-250 include one 500-amp, 50mv meter shunt, one combined ground/negative terminal bus bar and one isolated positive terminal bus bar.  more details
