MC4 to SAE adapter cable

I have the 100 watt Renogy portable solar kit, which comes with the MC4 connectors. I just purchased an Aliner Expedition which is "solar ready" and has the SAE connection. Does anyone know if there is such a thing as an MC4 to SAE adapter cable and where it can be purchased? Appreciate any suggestions.

    Yes they exist easy to make your own but google to find one they will most likely ship from China

    Is it that dreaded 2-pin connector that they put on cheap 5W solar chargers? Cut it off and put MC4.

    I actually need to include the dreaded 2-pin connector. As has been suggested, I'll have to make my own MC4 to SAE cable adapter. Thanks all.

    and +1 for this one. That two pin connector is a failure waiting to happen and will make you very dissatisfied with your solar.

    open the box on the back of the panel and rewire how you'd like.

    Actually I would prefer to pull new wire and avoid an extra connection.
    New MC4 cable direct from panel to controller.

    Good idea. Using the existing cable to pull a new one. Buy MC4 extension 2 times longer than the distance you need, and cut it in half so that you'll have 2 wires with one bare end and one MC4 connector each.
