We are transitioning away from the CEC to SAA but what about accessing those approved inverter and panels lists?
The CEC made it a bit difficult to search for panels, inverters but there has always been the Clean Energy Regulator. They provide the info via spreadsheets which makes it incredibly easier to filter and search for these products.
