To remain on the approved product list, manufacturers were required to supply evidence of compliance with updated region settings under AS/NZS 4777.2:2020 Amd 2:2024 before 23 August 2025. 

A list of inverter models for which manufacturers have complied with this requirement can be found below.  We have now removed non-compliant inverter models from the approved product list. Installers and retailers should check the approved product list to ensure their inverter models are still eligible for small-scale technology certificates (STCs).
