This kind of puzzles me, as we had solar put in about 15 months ago, in South Australia.
AGL retailer for power before and after, SAPN (South Australian Power Networks) the state power supplier.
We didn't (*weren't supposed to) have to do a thing, the solar company was the ones that looked after all the background tasks like changing to smart meters, liaising with SAPN for grid ok, network info to have 2 way power to / from the grid, etc.
We just advised AGL we were getting solar on, and picked a plan.
* Now I say weren't supposed to have to do anything loosely.
After a week and a half of the system being installed, but not able to export properly (the old meter was winding back with solar, and up with excess usage as usual), I called SAPN and they didn't have anything booked in for us, so did so at the time, with some numbers off the solar peoples paperwork I had to give them.
The new meter(s) got installed, and then some minor tweaking by the solar co and we were on the 2 way comms for usage and solar feed . . . not properly, but that's another story !!
We never had to pay anything over the solar quotation, not sure if different in other states, or if that's changed in 15 months, or maybe there is some sort of charge built into the solar quote for metering change, but here power cos are offering upgrades to digital for years at no charge.
We might not have had to get digital meters reconfigured, as they were new, so glad I always refused upgrades as we might have had a similar issue.
Hopefully you can all get sorted out without too much cost, or maybe a goodwill type of offer from AGL.
