I have the Mppt tracer 4215BN 40a. 4000w inverter. 5A 60W DC 24V To DC 12V Step Down Converter Regulator. 2x 275w solar panels
2x 140ah deep cycle batteries. 12v fuse box.
I'm in th United Kingdom and need to get the correct gauge wire and circuit breaker.
I think your 6 gauge is 4mm and 0 gauge...
