Load control requirements for EVSE in South Australia

The Smarter Homes regulations require that all new hard-wired EVSE installed in SA (residential or small-business sites) support remote demand response capabilities. To enforce this, the OTR has published a Technical Regulator Guideline, that specifies the technical requirements for installation of EVSE. Public charging stations and DC fast chargers are exempt from these requirements.
What communication protocols must EVSE support?
To qualify for registration, EVSE must support at least one approved demand response communication method:
- OCPP 1.6 (J/v2 or higher):
- ANSI/CTA‑2045-B (2021)
Alternatively, the EVSE can be “Deemed to Comply” by the Regulator by any alternative method the regulator approves as equivalent.
Requirements for vehicle-to-grid chargers
From July 2026, vehicle-to-grid-capable EVSE must also support OCPP 2.1 and the forthcoming AS 5438 (CSIP-AUS) interoperability standard.
Requirements for EVSE installations
The OTR maintains a EVSE registered equipment compliance list that lists equipment approved and registered with the technical regulator. Installers are only permitted to install equipment that is on this approved equipment list, and installations with equipment not on this list are considered non-compliant.
During installation, the installer must verify the charger supports either OCPP 1.6J or ANSI/CTA-2045-B protocols and can execute “load off” and “partial load” commands. EVSE is to be installed and configured in accordance with the OEM’s instructions but is not required to be tested on site with the SAPN or OTR through a capability test. OEMs must therefore ensure that they provide installers with clear information and instructions to simplify the installation process and mitigate any common issues with commissioning.
Following installation, installation details are documented via the electronic certificate of compliance which links the installation to the installer in the OTR's database.
Purpose of Smarter Homes regulations
The Smarter Homes regulations are intended to ensure that residential EVSE can participate in future smart charging programs or enrol in a network load control scheme, although no such programs for EVSE are currently active in South Australia.
