Information for technology providers

From late‑2026, new and upgraded solar inverters connected in NSW will need to support requirements introduced under the NSW Government’s Emergency Backstop Mechanism.

These changes are designed to:

• Support safe operation of the electricity network
• Enable secure, standardised communications with distribution networks

Certification and listing requirements

From late‑2026:

• Solar inverters must include a software communication client that complies with Common Smart Inverter Profile – Australia (CSIP‑AUS)
• The applicable version will be SA TS 5573:2025

A list of compliant inverters and software communication clients is published by the Clean Energy Council.

Endeavour Energy does not require OEMs or aggregators to separately test or certify products against our utility server.

Before a CSIP‑AUS compliant inverter can be installed and commissioned, OEMs and aggregators must onboard with each distribution network they intend to operate in.

The onboarding process:

• Is common across all NSW and ACT distribution networks
• Enables access to digital certificates required for secure communications

What the onboarding process involves

At a high level, onboarding includes:

1. Application – complete the onboarding form
2. Initial review – preliminary approval by networks
3. Basic communication testing
4. Full application – confirmation of compliance with common requirements
5. Approval and onboarding

Detailed steps and templates are provided in the NSW/ACT Utility Interconnection Handbook

As part of onboarding, applicants declare they:

• Meet common cyber security requirements
• Will comply with agreed network conditions

If you’re an OEM, aggregator or technology provider with questions about:

• CSIP‑AUS adoption
• Onboarding in the Endeavour Energy area
• Emergency Backstop implementation
