Would someone with more knowledge please elaborate on this? Batteries can be wired in parallel or in series. What about inverters (AC) ?

assuming you mean the output side of inverters, nope, in a nutshell. In theory if you could synchronize the phase output you could parallel them, but in reality this would be quite difficult and there is no point in doing so. There would be no benefit to trying to put them in serial.

There are stackable inverters out there. That's why I asked. Apparently, there is an advantage to parallel implementation. ...
