The panel I show at the beginning of this thread was a gift of some sort...lol. also the 8 gauge wireing.;)

Its a big panel..If I were to have to buy it it would have cost about 250 bucks.. I dont know what the 50ft og 8 gauge wire would have cost me..

I also bought this bargman 8 gauge trolling motor plug..


female end plug.


Male end plug

And some wood to mount everything to..

Also these pin connectors from didgi key.. Bacuase they seem not to make ring terminals in 8 gauge to fit the #8 stud on the mppt controller. I soldered there on the wire and heat shrink tubed the ends..

Hope this helps you...
