Solar Power Extension Cables

These cables are used between photovoltaic panel, panel arrays, combiner boxes, inverters and chargers. We use ONLY genuine Multi-Contact brand MC3 and MC4 connectors and housing. The wire is a black UL listed 8,10,12 AWG sunlight resistant cables.  They typically have a male connector on one end and a female connector on the other end.  Use them to extend module output cables or cut anywhere along the wire to obtain the needed length of male and female cable to run from string of modules to a combiner box or to a longer cable.

Power Cables

These cables are high quality Flex wire UL 1232/1283/1284 or 1346, 600V, 105C, Class K stranded wire. The lugs are 3/8" stud, non-insulated, closed end (for corrosion resistance), tin plated ring terminals. Both ends are covered with protective heat shrink. These cables are recommended for inverters and battery interconnects.

Solar Branch Connectors

These are used to parallel connect multiple solar panels or groups of solar panels together in a solar array. The unique design offers greater directional ease in laying out the the branch lines. The molded in eyelets allow for easy tie wrapping of the branch connectors to the structure.
