Important changes start from Monday 23 November: NSW CER Installer Portal

What is happening?

From Monday 23 November 2026, changes will apply to new and upgraded solar and battery systems up to 200kW. These include an updated connection application process, mandatory use of the NSW Consumer Energy Resources (CER) Installer Portal and the staged rollout of Emergency Backstop.

1. Separate connection application: Use the Embedded Generation Application for Connection for solar and batteries and apply separately for other electrical work. For sites in the postcode rollout, select CSIP-AUS compliant equipment from the drop-down lists, then confirm whether internet access is available. These sites can choose flexible export limits of up to 10kW per phase.
2. Pre-Installation device update: This will replace the Intent to Connect for solar and batteries under 200kW and allow you to update the device details in your application before installation. Note: You cannot go back and update details once you start the installation in the CER Installer Portal.
3. NSW CER Installer Portal becomes mandatory: Applications approved from 23 November will automatically create jobs in the NSW CER Installer Portal for installers to complete. This includes the submission of your embedded generation compliance certificate (CCEW) and updating the DER register. Training is available now and visit the support page for guidance.
4. Emergency Backstop rollout begins: Requirements will roll out by postcode from 23 November 2026 to early February 2027. The postcode checker shows when Backstop applies in your area and the supported equipment list identifies the inverters and Software Communication Clients you can use.

What do you need to do?

1. Complete the NSW CER Installer Portal training now, then register for access from 23 November. Important:
   • Choose Installer/Applicant if you both sell and install solar, Applicant if you only sell solar, or Installer if you only install solar.
   • Enter your profile details exactly as they appear on your electrical contractors licence and in the Australian Business Register.
2. Use the new Embedded Generation Application for Connection from 23 November and submit a Pre-Installation Device Update if device details change before installation.
3. Before quoting or installing, use the postcode checker to confirm when Backstop applies and make sure you use supported equipment.
4. Update your processes and share these changes with the relevant people in your organisation.
