Hi @Jaybeff51
As you have not supplied a few key pieces of info that is needed for myself so that I can try to help you.
All I can do is supply you with information on a case similar to yours.
My friend recently had a 13.2KW System installed 10KW Inverter.
And after her meter was reconfigured she found herself in your situation from single rate tariff to TOU, she had already nominated the equivalent of AGL's Solar Savers plan.
She is not with AGL but is with one of the big 3 , Her energy Distributor is Ausgrid.
And resides in Sydney NSW.
Two phone calls to her Retailer and she is now on a single rate tariff plan and on the equivalent to AGL's Solar Savers plan.
So in short yes other Retailers do this. It is up to you to action what you want.
PS: I do not work for AGL, I am just trying to give you some insight.
Regards
John
