As part of the State Government’s Energy Transformation Strategy, a new mandatory requirement for solar inverter systems has been introduced to enable better integration of solar generation into the south-west grid.
The revised Australian Standard AS/NZS 4777.2:2020 will include a mandatory requirement for all new inverters to have a voltage disturbance ride-through (VDRT) capability. This will be applicable throughout Australia from 18 December 2021 but the VDRT capability is being fast tracked here in WA.
From 1 July 2021, all inverters in WA that meet the previous version of AS/NZS 4777.2:2015 are required to have VDRT capability before being installed and commissioned. This implementation requirement was accelerated in WA at the request of the Energy Transformation Taskforce to reduce the number of inverters with lower specifications being installed prior to December 2021.
The change is a further step forward in managing distributed energy resources (DER) on the grid, paving the way for the continued rapid uptake of solar by Western Australian homes and businesses.
The new changes will have no direct impact on Western Australians who purchase PV systems, as the change is an installed setting change.
To ensure the continued support of and collaboration with the industry, Western Power invites you to register for their online information session on Thursday 27 May 2021 from 3.30-4.30pm.
