Applications

MC4 photovoltaic junction boxes are used to terminate and interconnect the wiring from individual solar panels within a PV array. The PVU-B48-022 was developed specifically for thin-film solar panel modules, which were widely deployed in utility-scale and commercial rooftop installations during the early 2010s. The male/female MC4 connector pairs allow panels to be strung together in series or parallel configurations quickly and without tools, with the IP65/IP67 protection rating making them suitable for outdoor installation environments. These junction boxes are commonly used in replacement, repair, and new installation applications for thin-film PV systems, and are sought by solar contractors, panel refurbishers, and PV system integrators working with compatible thin-film modules.
