From 1 April 2022, Australian manufacturers or importers of inverters eligible for STCs (and listed on the CEC's approved inverter list) are required to provide serial number data to the Clean Energy Regulator's inverter serial number ledger. This is a legal requirement under the under the Renewable Energy (Electricity) Regulations 2001.

The ledger stores all inverter serial numbers supplied to the Australian market that are eligible for small-scale technology certificates (STCs).

The Clean Energy Regulator (the agency) has developed guidance material to assist Australian manufacturers or importers of approved inverters to register and upload their data to the inverter serial number ledger:

Australian manufacturers or importers of inverters should provide their serial number data to the ledger as soon as possible after their product enters Australia. Data from products that were available in the Australian market from 12 months ago (1 April 2021) will need to be supplied. This assists to ensure serial number data is available to the agency for the purposes of assessing inverter eligibility in STC claims.

The agency will contact Australian manufacturers or importers when the inverter serial number ledger platform is available.
