Australia C – applies to the configuration of inverter settings in Tasmania. In doing this, you no longer need to manually set or change different DNSP settings. If you are unsure how to select 2020 Australia A settings on the inverter, please contact the manufacturer or your DNSP to confirm the correct AS/NZS 4777.2:2020 setting.
The regulation places definite limitations on inverter capacity and exporting levels for single-phase connections. For static connection, single-phase inverters can only be used up to 10 kVA, with exporting limited to 5 kW. On SWER lines, it is limited down to 2 kW.
To help improve safety and maintenance, AS/NZS 4777.1:2024 now limits the number of inverter main switches to two on any switchboard with loads. For installations with more than two inverters, an aggregation or marshalling board must be used, allowing a single switch to control all inverters.
To commission inverter settings using the default function on your installer app: Note that some inverters still show legacy options in their settings menu. In Victoria, all installations must select the Australia A option.
