Keep in mind that only the two connected MCBs and their related and connected load to the inverter will supply continues power in case of blackout.
Below is a given UPS Inverter connection and wiring diagram to the home supply. The circuit shows that only two rooms of the home are depends on the UPS and Batteries as well as main supply to maintain the uninterruptible power to the connected appliances and load such as lighting points and fans etc and the other loads are fed up by utility power only.

I think I have figured it out on which way should I follow as per your diagrams. Your posts helped me a lot. Because you said in your previous diagrams that there is no need to connect a neutral wire since it is assumed to be already connected to the mains electricity?
My question, is really on why is important to connect the neutral wire from UPS Output to main neutral link? Plus one more question from the phase output of the UPS instead of fuse can we use an MCB aka circuit breaker to help keep the circuit safe? Because the problem of the fuse is that if it breaks finding a replacement is hard so can we use an MCB switch instead of the fuse? Please sir, reply this too… :.

This component fulfils the second half of the double conversion by switching the DC voltage from the rectifier or battery back to an AC output that powers the critical load. This conversion process AC to DC to AC and filtering smooths out events such as spikes, sags, surges, and electrical noise, ensuring the final output is a pure sine waveform.
In the event of a UPS fault, the static bypass switch automatically connects the load to the mains supply, bypassing the rectifier, batteries, and inverter. Depending on the size and type of UPS, there are several other common components that may be included, for example, fans or capacitors.
