Check for correctness?

So I’m running a 24v system. Shown are:
-negative and positive bus
-Mpp all-in-one 2400 watt pure sine wave inverter with 80amp charge controller
-24v-12v converter
-AC and DC distribution panel
I’m running 4 100ah 12v batteries in series and parallel. Is there anything I’m missing/doing wrong. Thanks in advance.

I only see one fuse and i do not see any wire capable of 80 amps.
Wiring from solar panels will need breaker or fuse+switch.
Batteries heart of the system - how its wired and managed will be important.

We can only see a small portion.
