Still no closer to the answer, however, I've spoken to a couple of contractors who have installed multiple backup inverters and most of them try not to parallel inverters.
They say they spend too much time on the computer and online with the suppliers to get the parallel inverters working as they should.
Most of them say they prefer installing 1 inverter or split the load between multiple inverters and stay away from parallel units.
I know this does not bring one closer to solving the mystery, which is still puzzling, but it does seem that paralleling inverters can cause unnecessary problems which would otherwise not have been there.
