DC isolating switches in solar photovoltaic (PV) installations

From 30 June 2018, DC isolating switches used in solar PV and renewable energy installations must comply with a Level 3 certification under the Electrical Equipment Safety System (EESS). The new standard has improved safety outcomes for isolators used in renewable energy installations.

This means DC isolating switches must have a valid Certificate of Conformity confirming the product complies with Australian Standard AS 60947.3:2018. The brand and all relevant models must be registered to the responsible supplier in the EESS national database and be marked with the Regulatory Compliance Mark (RCM).

The EESS provides a transition arrangement to allow responsible suppliers to sell existing stock up until 30 June 2019.

In Queensland, wholesalers, retailers and electrical contractors may continue to supply or install the DC isolators they have in stock, provided the importer or manufacturer of the isolators is registered with the EESS and the isolator bears the RCM.
