Yes one plug in central driver board that can be very quickly replaced if it dies. Although I am not sure paralleling is the best overall strategy.
How about one inverter for the main house load, perhaps a second for heavy airconditioner loads, that might be turned off most of the time.
Maybe a third for some large workshop power tools, that might also be turned off sometimes.
If something smokes, a bit of unplugging and plugging in might get the show back on the road very quickly.
Another thing to think about. If your only inverter dies after the grid has gone down, how do you fix it without power for soldering iron, oscilloscope etc ?
I only have one inverter, but its completely modular, and I have a full set of spare boards and multiple spare IGBT modules. These can be very easily swapped out and I can replace whatever smoked by candle light if necessary, with nothing more than a screwdriver. Definitely no soldering required, no matter what.
