I Have room in the main panel to configure the external A-C supply and the A-C from the inverter. Is this:
#1 Safe?
#2 Smart?
#3 Legal?
Also, can these supplies share the neutral bus bar?
You need to be clearer on exactly what you mean by "configure."
If you mean connect the output of the inverter to the panel via a breaker added to an empty slot, that is neither safe nor smart nor up to code.
If you mean connecting an inverter/charger's AC power in to the panel, and then connecting circuits to its output (and so using its built-in transfer switch), then that's a reasonable plan and generally how things are done...but of course there are plenty of ways to make mistakes or do things improperly, as with any wiring project.
