Changes to solar inverter systems standards - online information session

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 is being accelerated in WA at the recommendation of the Energy Transformation Taskforce to reduce the number of inverters with lower specifications being installed prior to December 2021. 

In determining if the inverter is compliant, Inverters that meet the 2015 version of AS 4777.2 will be required to demonstrate compliance with the new voltage disturbance ride-through test protocol that was developed by the Australian Energy Market Operator. Western Power will be using a list of inverters compliant with the new test protocol on the as provided by the Clean Energy Council CEC website.

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. 

To ensure our continued support of and collaboration with the industry, we hosted an online information session on Thursday 27 May 2021 from 3.30-4.30pm.

By working together, we can continue to ensure that Western Australia remains at the forefront of the changing energy landscape and continues to deliver a brighter energy future for the community.
