^Like I said, no harm, no foul. I’m sue your setup works great.
It’s just not necessary to use wire that size.
Starter motor on a diesel pickup pulls 450+ amps through 2/0 wire, for comparison.
More so posted for others who don’t have the knowledge, that they do not think 4/0 welding cable is required for this setup.

Happy New Years !
wow, I dont know if I would use 4/0 for anything but welding haha. I dont have a situation where I have to carry 400plus amps up to 30 feet away. but ya if you got it use it.
Every wire gauge calculator I've tried recommended 4/0 cable for my setup, and my lengths are nowhere near 30ft. From the battery bank to the bus bars is 3ft, and from the bus bars to the 3000 W inverter is 5ft. At 300 amps for a couple of minutes (say running the microwave), those wires heat up fast. I'm not going to gamble an expensive set of batteries for a couple of bucks.
