Hello Everyone! Hope someone from this thread will still be able to patiently have a look at my updated schematics, wire sizes, fuse sizes and dc breakers please.
I have re-read
@smoothJoey 's initial post many times with wire and fuse sizes, then have read again the manuals for the Multiplus II and SmartSolars.
Here is an updated version of my schematics. I have oversized some of the wires but kept to the fuses as per Joey's recommendation and the manuals. Following the schematics you can find the screenshots from the manuals regarding fuses and wires.

The following is from the Multiplus II manual (shorturl.at/ayIT0), page 13.:

For the DC breakers between the solar panels and MPPTs, which of the two would you recommend? I suspect the thermal one has an extra layer of protection.
For that Class-T 300 A fuse, between the battery and the inverter, could I not use a DC breaker instead?
Similarly, would it not be better to have a DC breaker between the inverter and the busbar, rather than the 250A megafuse?
I know DC breakers are more expensive, but looking at doing the best option in the end even if it is going to cost more.
Thank you.
