Information for solar retailers and installers

There are a number of requirements you must be aware of before installing a solar system. We’ve compiled the information below to assist you before you begin your installation.

New solar and battery installation process

From November 2026, new solar and battery connection and installation processes will begin rolling out across NSW.

For eligible new and upgraded CER systems, where a DNSP connection application is submitted and approved from Monday 2 November 2026, installation activities will move to the new NSW CER Installer Portal.

This includes completing the Installation Notification and submitting the Certificate of Compliance for Electrical Work (CCEW) through the portal.

As a Solar Retailer (Applicant), you'll continue to submit connection applications through the Endeavour Energy Generator Form and use the NEW NSW CER Installer Portal to manage installation activities.

You'll need to:

• Continue submitting connection applications through the Endeavour Energy Generator Form
• Flexible Export and Fixed Export site plans will be assigned as part of the application
• Register as an Applicant in the NSW CER Installer Portal from 2 November 2026
• From 2nd November, Use the PTC Reference Number (DNSP ID) from an approved connection application to complete your portal registration
• Allocate installation cases to Installers through the NSW CER Installer Portal
• Encourage Installers to register in the NSW CER Installer Portal from Nov 2nd.
• Complete NSW CER Installer Portal training to prepare for the new process

As an Installer, you'll use the NEW NSW CER Installer Portal to complete installation, notification and commissioning activities.

You'll need to:

• Register as an Installer in the NSW CER Installer Portal from 2 November 2026 using your valid Electrical Licence
• Complete NSW CER Installer Portal training before the rollout begins in your postcode
• Claim installation cases assigned to you through the NSW CER Installer Portal
• Verify site, connection and equipment details before commencing work
• Complete and submit the Installation Notification
• Submit the solar installation CCEW through the NSW CER Installer Portal
• Ensure compliant devices have an active internet connection available on site
• Register devices with the manufacturer's platform where required
• Complete Device Registration Verification and Capability Testing when these requirements become mandatory for your rollout postcode
• Successfully commission the installation

The NSW Emergency Backstop Mechanism requirements will be phased in from November 2026, in parallel with the launch of the NSW Government’s Consumer Energy Resources (CER) Installer Portal, through which all new and upgrading solar systems will be registered and commissioned.

Endeavour Energy has updated its Permission to Connect for solar installations to manage the phased transition of incoming requirements. Solar installers are responsible for installing rooftop solar systems in accordance with the approved Connection Contract and the Schedule of Site-Specific Conditions, which include:

• Installing equipment that is compliant with the Australian Standard ‘Common Smart Inverter Profile – Australia’ (CSIP-AUS >=v1.2).
• Conducting a short capability test at the time of installation, confirming connectivity to Endeavour Energy's utility server via the internet. The test is conducted using the NSW CER Installer Portal.

These requirements will not apply to existing rooftop solar systems. Exemptions will also apply to embedded network customers or those seeking a like-for like replacement (e.g. under a manufacturer’s warranty).

If internet connectivity isn’t available during installation, the system must still be registered and complete the required CSIP-AUS testing. In these cases, a temporary 1.5 kW export limit will be applied until a reliable internet connection is available. This applies to sites with poor connectivity and new developments awaiting internet services. Where registration cannot be completed because no internet, hotspot, 4G or 5G connection is available, an exemption pathway may apply. For more information, see the government factsheet.

These requirements do not apply to:

• Existing solar systems
• Like‑for‑like replacements
• Embedded networks
• AC Coupled batteries
• Sites where home internet or mobile internet has not been established

Installers will be responsible for confirming compliance at installation.

Find out more about the NSW Emergency Backstop Mechanism.

For embedded networks:

• Are exempt from other NSW Emergency Backstop requirements
• Multi-tenant sites may be considered if it is managed by a Solar Site Controller (SSC) such as Solshare

Approved export limits represent the maximum allowed export (for a flexible export connection or a fixed export connection), not guaranteed output.

Actual export varies based on:

• On‑site self‑consumption
• The customers’ choice of a flexible export connection or a fixed export connection
• Participation in a third-party Virtual Power Plant (VPP)
• Loss of internet connection to the solar inverter
• Inverter behaviour under AS/NZS 4777
• Local voltage conditions
• Inverter capacity and phasing

Voltage‑based export reduction is a normal and required feature to protect the network.

As the installer, you’re responsible for:

• Completing electrical safety testing
• Submitting a Certificate of Compliance for Electrical Work (CCEW) to the Building Commission NSW within 7 days of completing the installation. Please note that Endeavour Energy does not retain Solar CCEWs and does not require a copy to be submitted to us.

Endeavour Energy audits some installations after connection. These inspections may occur months after install due to volume. Unsafe systems may be disconnected immediately.

To design or install solar or battery systems in Endeavour Energy’s network, you must:

• Hold current Solar Accreditation Australia (SAA) accreditation
• Have a valid NSW electrical licence
• Follow any additional manufacturer training requirements for the equipment you install

If you don’t currently hold SAA accreditation but believe you meet the required training standards, contact us to discuss your situation: connections.

Correct design upfront reduces delays, defects and rework. Installers should pay particular attention to:

• Internet connectivity
• Voltage rise compliance
• Main switchboard suitability and compliance
• Battery placement requirements
• Additional protection requirements for large systems
