Hello guys, just had a pop top fitted which I’m really pleased with, the installers ran some cables from the back of the pop top towards the drivers seat where I would position the MPPT controller. The trouble is these are 3mm SQ . Now I know nothing about cable sizing but I did have a quote from 12v planet to supply a 150W panel,75/15 MPPT and a 105 ah lithium battery,on the email they recommended I increase the cable size to 10mm SQ because the run is over 5 meters. So do i need to swop these cables? Will the cable off the solar be 4mm? Do I use a thru crimp where they enter thru the pop top to get from one size to the other? Do I put a fuse at the earliest opportunity ? All so confusing to me.
