P.S.
In many cases it would be necessary to use a fused AC disconnect to
stay within the inverter manufacturer's specifications.

Here is a wild idea. If you look at the Enphase inverter systems,
several inverters connect together in parallel before going to an
overcurrent device.
In all cases, the point of connection to a utility system must be at
a dedicated breaker. If there were multiple string inverters that
would connect to one breaker, why not just use a junction box,
instead of a combiner panel? You could put in an AC disconnect for
each inverter, if it didn't come with one.
The wiring would need to be sized for the combined output of the
multiple inverters, which in many cases wouldn't be an issue.
