I have six Nissan Leaf second life batteries set up with 2 sets of 3 modules paralleled. And when I do connect this BMS from Overkill solar I will also connect a 40A solar charge controller and 200W of solar. If I'm right this should create a 12v system I could start running lights and other small 12v things with.
I don't have the components yet as I haven't decided what would work best. Though I intend to add DC to DC charging from the vehicle and an inverter to charge the system with as well as run higher voltage appliances here and there. Recommendations for these and how to incorporate them would be appreciated.
I have fuses, wires, a couple master power cut off switches. And determination to get myself some real running power!
The first thing I want to confirm is that the arrangement and setup of my wiring looks correct. (Please see edited photo of hypothetical wiring)
The BMS for the most part seems like it will be fine but C- being my main negative seems a little odd. Do I then connect it to a bus bar to evenly distribute the load, and then have that go to one wire that is my main negative for the charge controller?
Second, almost inline with my initial question I am unsure I understand where my main negative and positive posts are supposed to be, and do they connect directly to the solar charge controller? Another side question is what size wire you would recommend running from the batteries to carry the main current? ( 4.0AWG?)
So I was hoping to just get a little direction as well with how everything else comes together in this. I understand wiring up my lights, and switches but not exactly where to bring in my little fuse box and connect all these to the battery bank.
This entire setup is going to live in a Chevy van that I happen to call home.
Any and all help and direction or tips are so very appreciated. Ill definitely keep this up to date with my progress.
Thanks so much.
