I am assuming that your cable length purchases are close to your actual run lengths? If that is the case I would really try to look at your layout o shorten the 2/0 runs. If you can keep them around 5’ for both the + &- runs you will have better results when done.
Your battery negative to your shunt is sized at 2/0. Then from the shunt to the negative bus bar is also 2/0. The bus bar to frame ground only needs to be a #4 I believe. This should be the only bonding point. Don’t forget the equipment grounding conductor for your inverter as well. The size should be noted in your inverter documentation. Probably a # 8 or 10.
