An inverter compliant with an earlier version of AS/NSZ 4777.2 can be replaced under warranty where:
- The replacement inverter is the same make and model (like-for-like).
- The replacement is for warranty purposes.
- The inverter is set up to comply with the existing connection agreement.
Applications are required for warranty replacements. Where the above requirements are not met, an AS/NZS 4777.2:2020 inverter compliant with the latest standards will be required.
Installers are required to submit a connect application and receive approval for all replacement inverters, including warranty replacements, prior to connection.
Did this answer your question?
We encourage everyone to use our online services or contact an electrical contractor or solar installer to submit on your behalf, as this is the quickest way for us to assist.
However, we have printed versions of our enquiry form and connection application form that we can send to you. Give us a call on our general enquiries number to request a form.
Did this answer your question?
Yes, your electrical contractor or solar retailer/installer can apply on your behalf via our Electrical Partner’s Portal.
Sometimes it’s easier to have them apply for you, as some technical information is required.
Did this answer your question?
No. The GSD is not a network device, it is part of the customer installation.

If you are considering buying a solar PV system and your electrical installation is wired for 3-phase, or could be economically upgraded to 3-phase, we encourage you to consider the benefits of installing a 3-phase inverter, particularly for inverters rated above 3 kVA.
Although 3-phase inverters are more expensive than single-phase inverters, spreading the inverter capacity across more than one phase will likely result in more stable operation, with less problematic voltage excursions and nuisance tripping.
This may provide a higher output of PV generation and longer life for your PV system, leading to a better investment return.
More specifically, the connection standard requires that if your inverter will be rated greater than 10 kVA and/or will be set to export more than 5 kVA, then it needs to be a 3-phase inverter. A 3 phase inverter may be installed up to 15kVA with automatic approval.
If you have a 2-phase electrical installation, we encourage the use of two single-phase inverters to spread the inverter capacity across both phases.
The connection standards also require that if the voltage rise from the network connection point to the proposed inverter is above 2%, then a 3-phase inverter must be installed. If the electrical installation is not 3-phase, or unable to be made 3-phase, other actions will have to be taken to reduce the maximum voltage rise to 2% or less.

Yes. You will need to have a compliant inverter or gateway device installed with your system. Your installer will help you to determine the most cost-effective solution from the range of options and equipment available.
Installers can contact a company on the Dynamic Connections Compliant Providers list (PDF 215.8 kb) to enquire about the current approved inverters and devices for Dynamic Connections. The number of providers will continue to grow over time as more systems become certified with our utility server.

The GSD utilises the existing connection available for the demand response mode function – this is via an external port or internal terminal block, depending on the make and model of the inverter.
For technical requirements and general guidance on installing the GSD, please refer to section 8.10.2 Emergency Backstop Mechanism of the Queensland Electricity Connection Manual (PDF 19.8 mb).
For installation of the GSD:
- Connection may vary depending on inverter manufacturer but is typically via the RJ45 port or 8 pin round communications port or internal terminal block
- In some cases, the settings in the inverter may also need to be configured to ensure it is enabled for 'DRM 0' mode
- The GSD manufacturer(s) will provide generic instructions on installation of the device. We are aware that previously printed versions of the manufacturer’s instructions may differ from the QECM supplement in relation to where the GSD can be mounted and the requirement to have a GSD for each inverter. Where there is a difference, the QECM Supplement should be followed
- Inverter manufacturers may also provide model specific instructions for connection and activation of the 'DRM 0' function, with some inverters requiring an extra module to be purchased to enable 'DRM 0' mode.

We have two online portals for our customers to submit connection applications:
- Customer Self Service - Anyone can register and apply to Customer Self Service. This is the best way to submit your connection application
- Electrical Partners Portal - If you regularly submit connection applications as part of your work, we recommend you sign up to our Electrical Partners Portal. We recommend this online service for electrical contractors, developers, builders, and government. Electrical contractors will need to enter their licence details when registering online to use the portal. Other customers wanting to register for the Electrical Partners Portal will need to contact us on 13 12 53 to register.

The commissioning check should ensure the correct and safe installation of the GSD in compliance with the DNSP standards and manufacturer instructions. Where the GSD has been installed correctly and the inverter configured correctly:
- The removal of the RJ45 plug from the DRM mode port on the inverter, or disconnection of the GSD from the terminal block, will trigger the DRM 0 functionality to cease generation as per clause 3.2.2 (d) of AS/NZS 4777.2
- Another option to check that the DRM 0 mode has been configured correctly is to use a test module as described in Appendix D in AS/NZS 4755.1.
