The Clean Energy Council maintains a list of compliant inverters and power conversion equipment (PCE) that is approved for installation under the Renewable Energy Certificate scheme. This list is also used by some Distribution Network Service Providers to validate inverter energy system applications.

The equipment listed has shown sufficient evidence that it meets the required safety standards for usage within Australia.  Evidence of compliance, in the form of Certificates of Suitability have been examined and verified by the Clean Energy Council.

Inverters and network requirements

Listing of an inverter or PCE on the CEC approved product list does not grant automatic rights of connection of these devices to networks. Individual network distributors may have additional requirements above and beyond the CEC list requirements.


The CEC accepts certificates from the following Joint Accreditation System of Australia and New Zealand (JAS-ANZ) accredited certifying bodies or state electrical regulators:

Note: if you have certificates from a non JAS-ANZ accredited organisation, we advise that you submit these and their accompanying test reports to a state electrical regulator for assessment, in order to obtain a Certificate of Suitability from that state regulator.

The certificate from the state regulator can then be uploaded with the application. State regulators are Energy Safe Victoria, Electrical Safety Office (Queensland) and Office of Fair Trading (New South Wales).

Equipment definitions

Stand-alone inverter

An inverter that is not designed to inject power into the grid, and is used for the supply of extra-low (ELV) and/or low voltage (LV) electric power to a single load, or an electrical installation via batteries or a renewable resource, PV, wind, hydro etc.  The inverter may or may not contain a charging function.

Stand-alone inverters with connection ports for ELV batteries must be isolated type only.  The CEC will not list non-isolated (transformerless) stand-alone inverters, as these do not comply with the installation requirements of AS 4509.1 (refer to Clause 9.3.3).

Multi-mode inverter

An inverter that operates in more than one mode; for example, having grid-interactive functionality when mains voltage is present, and stand-alone functionality when mains supply is de-energised or disconnected.  A stand-alone inverter that can inject energy into the grid would be considered a multiple-mode inverter.

To qualify for listing in this category, the CEC requires multiple-mode inverters to be tested and certified to IEC 62109.  Depending upon the way in which they operate, they may also need to be certified to AS 62040.1.1 (e.g. if there is no break in output power supply when switching from one mode of operation to another.)

Power conversion equipment (PCE)

An electrical device that converts one kind of electrical power from a voltage or current source into another kind of electrical power with respect to voltage, current and frequency. This listing category is for devices which are not inverters, but are connected between a PV array source and an application circuit.  Examples include DC/DC converters and charge controllers. DC Conditioning units are not considered to be PCE (see AS/NZS 5033:2014, Clause 2.1.5).

Inverter standards

The following table shows the safety standards that an inverter or PCE should be certified to, in order to be included on the CEC Approved Products list.

Because the table may not cover all types of devices or all relevant standards, equipment suppliers shall also consult with one of the certifying bodies as to their particular requirement(s) for the specific equipment.

Grid Control Devices

See Note 4 below



  1. Combined “inverter and battery storage” products which only operate when the mains grid is connected (i.e. which do not operate in a stand-alone mode) will be listed under the “Grid Connect Inverter” category, either <30kW or 30-200kW.

  2. Australian Standards AS4777.2 and AS4777.3 currently apply only to inverters with rated output of up to 30kVA.  However, the test methods described in these Standards may be used for inverters over 30kVA (as described in Section 1 of that standard).  Hence, the CEC require grid-connected inverters over 30kVA to be certified as compliant with the requirements of AS4777.2 and AS4777.3, to be listed.

  3. Regarding off grid inverters: where the inverter has a direct connection port for a solar PV array or other renewable source, the CEC requires that it is certified to IEC 62109-2 in order to be listed.  Where the inverter only provides power conversion to/from a storage source and an AC installation, the inverter only needs to be certified to IEC 62109-1 to be listed.

  4. Regarding grid control devices: The current draft revision of AS4777.2 “Grid connection of energy systems via inverters – Inverter requirements” includes test procedures for demand response modes of inverter equipment.  This Standard is expected to be published in late 2015, and once this occurs, the CEC will be able to confirm the requirements for grid control devices to be listed on the Approved Product list.  The CEC will also advise of listing requirements for “export limited” inverters at this time.

  5. The CEC does not currently include requirements for Electromagnetic Compatibility (EMC) in Approved Product listing requirements for inverters and PCE.  Certification of installed equipment for EMC may be required under other regulations (e.g. state electrical Regulations).
