New DER technical requirements for consultation

We’re working hard to enable more households and businesses to connect to the benefits of rooftop solar. The good news is, we'll soon be updating our DER Technical Requirements to remove hosting capacity restraints across most of our networks.

To facilitate this change, all new connections will need to be energy managed  - with the introduction of Smart Connect Solar.

We want the industry to have a say on the proposed changes

Before they take effect in 2024. This is an opportunity for you to understand more about these changes and provide your feedback.

Download a copy of the draft Technical Requirements below.

You'll need to complete our new Clean Energy Council micro-accreditation

To install Smart Connect Solar. Get ready and complete the training before the new technical requirements take effect early 2024.

What's changing?

To enable more households and businesses to install rooftop solar

Most systems will need to be energy managed via a Secure Gateway Device connected to Horizon Power's DER Management system (DERMS).

  • The draft Technical Requirements for Basic EG Systems - outlines compatible inverters, internet connection options and how to commission Horizon Power's SGD during install.
  • The draft Technical Requirements for Low Voltage EG systems - have been updated to facilitate the new DERMS requirements and SGD supplied by Horizon Power.

All new connections will be energy managed
we call this Smart Connect Solar

As more renewables connect to the network, it becomes harder to maintain a stable power supply because they  were originally designed for one way flow of electricity.  Smart Connect Solar means more rooftop solar can be connected without impacting network stability.

Compatible inverters

For Basic EG connections, only the following inverter makes and models are initially compatible with the SGD (supplied by us). This list will continue to grow as more inverters become compatible.

All systems must be configured with Australia Region C settings in accordance with AS4777.2:2020

All systems must be configured with Australia Region C settings in accordance with AS4777.2:2020.

Horizon Power has been made aware of an issue with the connect and reconnect over-frequency setting in AS4777.2:2020 (Section 4.7 in our DER Technical Requirements). For new Basic and LV EG connections, this setting is required to be updated to 50.5Hz to comply with the new draft Technical Requirements.

Horizon Power is working with Standards Australia to have this updated in AS4777.2:2020. However, in the interim, a manual update to this setting is recommended to ensure inverters operating in our service area work correctly.
