These are the 10 gauge wires we used to connect our solar panels to our solar charge controller. On one end they have MC4 connectors and on the other end are open wires you can strip back. You can watch our install video here.
We probably could have stuck with 12 gauge wire, but decided to make sure they were wide enough for the journey through the RV.
