It seems the transformer, and the components immediately around the transformer can have multiple resonances with various amounts of coupling and damping, also influenced by the nature of any inverter output load. Its all a bit of a dog's breakfast and very difficult to analyse. Adding our primary snubber inductor will also influence all of that as we already know. Looking at the awful waveforms coming straight off the grid, I would not lose any sleep over a few low amplitude wiggles. Cheers,  Tony.
