Did you install a separate EGC?
Generally, the conduit feeding the panels, if continuous and tight should be sufficient to serve as an EGC and a bonding means.
Are there any eccentric or concentric rings left at the conduit connection point? Although bonding bushings are only required for Services, per 250.92, and 250 Volts or more, per 250.97, he may have concerns about loose conduit connections.
Ask him for specific references!
