i am looking to connect my Renogy 100watt suitcase to the Zamp connection that came with my 2017 FC 25.
What is the best solution for this connection? My understanding is that the Zamp is connected to the batteries with reverse polarity - I am struggling with how to get a cable that has MC4 connections on one end, SAE connections on the other, and deal with the reverse polarity at the batteries. The inside the box connections has an in-line fuse on the "+" connection.
Does anyone know if you can get a premade MC4 to SAE extension cable? I would like 30' in 10g but I can't find anything on line. If it exists I could just add a polarity reverser connection such as this: https://www.amazon.com/dp/B00AHCWGOO...6GOA9STN&psc=1
and be done?
Or, I guess I could get 10g 30' extension and reverse wire it into the charge controller, and then use an MC4 to SAE connector such as this: https://www.amazon.com/dp/B01N1TALFY...I1U5O3NFNTDJF6
to connect to the Zamp terminal on the Airstream?
Looking to do this with the fewest connections possible to avoid adding resistance to this setup.
