Solar PV and other Inverter Energy Systems with a Dynamic Connection will communicate with our “utility server”, via a WiFi internet connection. Regular signals will be sent to your inverter about the export limits that the network can accept. Your inverter will then control your excess energy exports within these limits.
Your system is likely to receive a higher export limit on hot days when electricity usage is high. Your energy exports will also depend on the available excess generation from your solar PV system.
If the connection to our utility server is lost, your system will default to a pre-determined varying export limit. After a day without a communication connection, your system export will be limited to a default export limit of 1.5kW typically.
Maintaining the connection between your system and our utility server via a WiFi internet connection is important to ensure your exports are maximised.

Ask local solar installers for advice on what is required to enable your solar system for a Dynamic Connection. They can also help you with the connection application process.
Installers can contact a company on the Dynamic Connections Compliant Providers list (PDF 215.8 kb), who can guide them through the process. The number of providers will continue to grow over time as more systems become certified with our utility server.
We also encourage any inverter manufacturers that have not yet gained certification with our utility server to refer to the Smart Energy Profile (SEP2) Client Handbook (PDF 662.1 kb) and get certified.

We encourage everyone to use the online services or contact an electrical contractor or installer to submit on your behalf as this is the quickest way for us to assist you.
However, we have printed versions of our enquiry form and connection application form that we can send to you. You can call us to request a form.

You would need to apply for a new connection agreement and ensure that the entire system complies with the latest applicable connection standard. Once you have received a new connection agreement and the site is compliant with all other requirements, the solar installer is able to upgrade your firmware.
Did this answer your question?
Essentially, yes. Whenever changes need to be made to your system, the installer or electrical contractor is obliged under legislation to ensure all wiring and replacement components meet current standards. This could create additional costs above the cost to replace the failed component.
However, if the inverter is being replaced under warranty with one of the same brand, series and model, it doesn’t necessarily have to comply with current connection standard. If not under warranty, the replacement inverter will need to comply with the current connection standard.

Speak to your solar installer, they can help you to understand your options and how a Dynamic Connection could benefit you.

No. In the case where a hybrid inverter is installed with no solar PV attached directly to it, just an energy storage device, it does not require a GSD.
If the customer wishes to add PV to this inverter in the future, a connection application would need to be submitted and a GSD would need to be added at that time, assuming the system otherwise met the backstop mechanism requirements (i.e. total PV capacity of 10kVA in a non-AFLC area) as outlined in the relevant Connection Standard.
Please note: The calculation of the total capacity includes all inverters on the premises, including those solely supplied by a battery.

Yes. You can install a 2015 compliant inverter from 18 December 2021 where the following criteria are met:
- You have a valid connection agreement to the electricity distribution network in place for a 2015 compliant inverter; and
- The inverter being installed was made in, or imported into Australia before 18 December 2021; and
- The installation occurs within the terms of the connection agreement, including the timeframes.
It is important to note however, that if you install a 2015 compliant inverter from 18 December 2021 that you will not be eligible for STCs or LGCs for this system. For more information see the Clean Energy Regulator website.
