Nissan Patrol GU4 2006 with Cummins ISDE4.5 270HP , 830 NM Engine Conversion
On my solar controller, there are 3 pairs connections for: solar input, battery, and final output. I have checked that their earths are not connected together. But i am thinking to join all the earth together, so i only need 3 +12 wires, plus one thicker common earth for all the 3 . Will this setup be OK?
