Dynamic connections for installers

To support more solar, batteries and other generation being connected to our network we are offering dynamic connections as a smart alternative to our normal connection arrangements. Read below to find out how a dynamic connection works and how to implement a dynamic connection for your customers.

The information applies to customers installing up to 30kVA of solar. Information on dynamic connections for above 30kVA will be provided here soon.

Dynamic Connection Standards

The connection standards for dynamic connections are applicable for the following connection types:

Export limit

Solar system details Result of initial solar application^
 No network restrictionsNetwork restrictions due to high solar saturation
Basic Connection Offer Basic Connection Offer Dynamic Connection Offer
Inverter size per phase 10 kVA (per phase) ≤10 kVA ≤10 kVA
Export permitted per phase 5 kW (per phase) 0 kVA 10 kW
Permitted #battery size (AC) – if solar inverter capacity of 10 kVA is utilised 0 kVA 0 kVA ≤10 kVA

The above table relates to customers on the main electricity grid – refer to STNW3510 (PDF 836.1 kb) for further details including limits applicable to customers on the regional SWER network.

# Please note a hybrid inverter is assessed as both a solar and battery inverter from an AC inverter capacity perspective. Both a basic connection and a dynamic connection can only have a maximum 10 kVA hybrid inverter capacity approved to be installed on a single-phase connection.

^Customers can request a network study to be carried out (fee applies) if they wish to be considered for a negotiated connection agreement that may result in different inverter / export arrangements being approved.

How to implement a dynamic connection

Selecting a dynamic connection is simple:

  1. 1 Connection application

    Submit the connection application via the Electrical Partners Portal

    You may choose to apply for dynamic connection at this stage, or you can apply for a basic connection and wait for the result of the assessment to then choose a dynamic connection.

  2. 2 Connection assessment

    We will assess the application and advise the outcome of the assessment

    If the outcome of the assessment is limited or no-export and this does not meet your needs, you may opt to change to a dynamic connection via the Portal.

  3. 3 Accept connection offer

    Accept the connection offer on behalf of your customer in the Portal

  4. 4 Installation

    Install the compliant dynamic embedded generating (EG) system with a compliant inverter or gateway device

    Ensure you follow any instructions provided by the manufacturer of the inverter or gateway device to understand the dynamic connection commissioning process.

  5. 5 Registration

    Complete our Dynamic EG registration form to finalise the system connection to our Dynamic Utility Server.

    Please note: You can complete the registration before installation of the system, which will allow you to confirm the inverter or gateway device is successfully connected to our server when you install the system (allow up to 10 business days for us to process your registration). If the connection is successful, the system will operate under a dynamic connection.

Our How to apply Dynamic Connections under 30 kVA (PDF 987.0 kb) portal user guide has been developed to assist when applying for a Dynamic Connection Offer in the Electrical Partners Portal.

Additional information

For a single-phase connection, you can have up to 10 kVA solar inverter capacity plus 10 kVA battery inverter capacity.

For dynamic connections using a hybrid inverter, a lower total limit of 10 kVA applies. For example, if you have a 10 kVA hybrid inverter, capable of connecting solar and batteries, the combined inverter capacity limits of each technology (eg. solar and battery) cannot exceed 10 kVA in total.

For a three-phase connection the limit is 1500 kVA.

The majority of customers on the network will experience either minimal to no limiting of their solar system’s export, most of the time. Export limiting is more likely to happen on clear, sunny days around autumn and early spring where there is also less demand on the electricity network and/or where there is a large number of solar systems installed on the local network. Under a dynamic connection, once the system is registered and maintains a communication link with us, even when there is a need to reduce solar export, the premises will still be allowed to export 1.5 kW, unless there was a significant emergency event requiring all solar generation to be restricted.

We are working hard to deliver this capability and we hope to be able to provide this function soon.

Yes, we have customer friendly information on our Dynamic connections for homeowners & small business web page. We have also have this Dynamic Connections Factsheet (PDF 1017.0 kb) that we encourage installers to provide to their customers.

Subject to any requirements contained in the site-specific technical study, a dynamic connection on a dedicated transformer (TX) can have up to:

  • Dynamic export up to 100% rating of the transformer
  • Dynamic import up to 120% rating of the transformer
  • Aggregate Inverter Energy Systems (IES) capacity up to 200% rating of the distribution
    transformer; where both PV and storage inverters are used. Note that PV inverters shall be limited to 120% of the distribution transformer capacity

in accordance with the requirements in STNW3511.

The Dynamic Operating Envelope (DOE) is calculated live and published to the proponent based on the Distribution Network capability at any point of time with a forecast of 24 hours given as a guide.

Please read our Dynamic Connections Factsheet - Dedicated Transformer Connections (PDF 312.4 kb) for how it works and some FAQs.

Dynamic connections CPD training

We have partnered with the Clean Energy Council to develop an online training course for installers. The course outlines how a dynamic connection works, the customer benefits, how to apply for a dynamic connection, and how to install and commission dynamic connections for EG systems (up to 30kVA) in Queensland.

To access this course, visit the Clean Energy Councils LearnLab - look for the course under 'CPD Core' category and use enrolment key QDC01. The course is eligible for Continuing Professional Development (CPD) under Solar Accreditation Australia’s CPD training, course code CPD037.

Dynamic connections compliant providers list

You will need to utilise a compliant inverter or gateway device. Installers can contact a provider from the Dynamic Connections Compliant Providers (PDF 218.7 kb) list to enquire about the current approved inverters and devices for Dynamic Connections. The number of providers will grow over time as more systems become certified with our utility server.

How do inverter manufacturers gain certification?

Manufacturers interested in gaining certification for their equipment (inverters, gateway devices) are requested to review the Smart Energy Profile (SEP2) Client Handbook (PDF 829.0 kb) and follow the steps to become a compliant provider.
