No, I mean you can parallel as many -48VDC input sides as you want, off a bus bar or battery setup, assuming that the wiring is set up right. The 120VAC outputs would of course be totally independent. Depending on your requirements it could be a better solution to a 1+0 "all eggs in one basket" large inverter setup, where if the inverter dies, all AC loads go down. In the sort of arrangement I mentioned the AC loads for things with dual power supplies could be built as 1+1.
