The only thing I would add is that I feel I want switches to shut off, individually, the inverter, charger, etc. So I would put breakers instead of fuses. I do not have any particular reasons in mind... I just feel I want to be able to quickly and easily get these high powered items out if their magic blue smoke starts leaking.
Another way of doing that that is elegant with two battery banks is to install master battery disconnect switches that distribute 12 V between the two banks and the devices, converter, inverter, and other devices. I built a distribution panel that does that and I can choose to connect various devices to either or both of the two banks. You need the three position master switches for this.
