Hi, sorry I am very new to this and building a 12v 3 panel solar array in parallel. My problem is I can only mount the panels at the bottom of my garden and the house is 75 feet away. I've not bought any gear yet as I am planning it all out first. My problem is that at 75 feet with 3 x 100w panels I've worked out I should need a 2awg wire to carry 20amps (rounded up). Will this fit into a standard charge controller? Am I working it all out wrong as it seems very thick wire? This is the only confusing part for me, especially since the wire is not cheap, so I need to get this right first time. The charge controller I am looking at is the EPEver Triron 4210N (40amp) and the panels (I already have) are Renogy 100w RNG-100D-SS. I am in the UK, Thanks.
