That is why I like exeltech. If an inverter dies, you only lose 1000 watts of capacity. So you put in enough modules for your load plus an extra module.

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.

Do you actually combine the outputs in parallel? If so you really cannot limit current to individual units, the load will divide across the inverters based on internal and external impedances.

You could also look into individual 1500W meanwell true sine wave inverters, running in parallel off your 48vdc battery bus. You can parallel as many as you need. Don't load any individual one with more than 1300W constant. Wire up the output from each meanwell to 120vac PDUs with amperage meter inline and distribute from there.
