I am installing a Victron Multiplus 12/3000/120. The manual calls for 2x 1/0 wires between inverter and the batteries, My question is would there be any downside to running a single 4/0. The distance between the battery and inverter is short about 4’. I know 4/0 is very thick and can be difficult to work with but I will going from the battery to a fuse then a switch and my thought is it would be easier to run a single 4/0 instead of parallel 1/0
