Use these cables to run power between solar modules and junction boxes.
MC4 and H4 connectors are almost identical, and fully compatible with each other. MC4 is UL listed and H4 is not UL listed.
These cables have the newer, snap-together Multi-Contact hard plastic connectors on each end. Use these output cables with many modules brands between module wires and junction boxes or grid-tie inverters. They have a male connector on one end and a female connector on the other end so they can be used to extend the cables on the modules or be cut in half and used to connect to a roof-top j-box or combiner. For example, if you need a 30′ male and a 20′ female, order a 50′ cable. Made with double insulated black #10 AWG, PV WIRE, USE-2 sunlight-resistant cable. Use the locking sleeve where a tool is required to disconnect.
