CER SRES Recalled Solar Product and STC Eligibility Guide: Navigating Australian Regulations

Key Takeaways

• Recalled products are ineligible for STCs under Australian Consumer Law (August 2026).
• Repaired or replaced products may regain eligibility if they follow the recall notice (August 2026).
• The ACCC recalled Sigenergy single phase 8/10/12 kW inverters sold between 04 March 2025 and 18 November 2025 (August 2026).
• Tesla Powerwall 2 batteries sold between 1 November 2020 and 23 August 2025 were recalled; replacement Powerwall 3 units are not STC eligible (August 2026).

What makes a solar product ineligible for STCs in Australia?

A product model is ineligible for Small-scale Technology Certificates (STCs) if it is subject to a recall under Australian Consumer Law (August 2026). The Clean Energy Regulator (CER) communicates with the industry following a recall notice publication from the Australian Competition and Consumer Commission (ACCC). This framework operates under the Renewable Energy (Electricity) Act 2000 and its Regulations 2001.

We verified these provisions on 23 August 2026, directly from the Clean Energy Regulator's official website.

Primary CER Product Recall Provisions for STC Eligibility

| Serial Number Evidence Workflow | "Once repaired, send evidence of the repair and the product serial number to the manufacturer. The manufacturer will pass these details to us to consider STC processing." | Figures as of August 2026.

Can a recalled solar product become eligible for STCs again?

Yes, a product may regain STC eligibility. The Clean Energy Regulator (CER) may consider a product eligible for STCs if you repair or replace it as outlined in the recall notice (August 2026). After repair, you must send evidence of the repair and the product serial number to the manufacturer. The manufacturer is then responsible for passing these details to the CER for STC processing consideration.

This process ensures that only products meeting safety and performance standards, even after a recall event, can generate STCs.

What specific product recalls have impacted STC eligibility?

Several product recalls have directly affected STC eligibility. These include specific models of Sigenergy inverters and Tesla Powerwall batteries.

Sigenergy Inverter Recall

The ACCC issued a recall notice for Sigenergy single phase 8/10/12 kilowatt inverters on 19 November 2025 (August 2026). This recall covers products sold between 04 March 2025 and 18 November 2025. Consumers affected by this recall will receive a free replacement product. This replacement product will have an updated AC plug. Retailers or Sigenergy Australia service partners will contact consumers to arrange these replacements.

Tesla Powerwall Battery Recall

Tesla issued a voluntary product safety recall on 16 September 2025 for some Powerwall 2 home batteries (August 2026). This recall applies to units available for sale between 1 November 2020 and 23 August 2025.

A key point for STC eligibility is that while the Tesla Powerwall 3 is an approved product under the Small-scale Renewable Energy Scheme (SRES), a replacement battery installed due to an ACCC recall is not eligible to claim STCs (August 2026). This applies even if the replacement unit is a newer model like the Powerwall 3.

How do you ensure STC compliance with recalled products?

To ensure STC compliance, you must adhere strictly to the Clean Energy Regulator's guidelines regarding recalled products. If a product is subject to an active ACCC recall, it is ineligible for STCs unless it has been repaired or replaced according to the recall notice.

We have not verified the specific repair or replacement procedures for all recalled products, so we do not publish them here. Always refer to the official recall notice and manufacturer instructions.

Where can you get support for recalled products and STC questions?

For support regarding recalled products and STC eligibility, you can contact the Clean Energy Regulator directly. They have a dedicated email address for such inquiries. You can email them at deemedunits@cer.gov.au (August 2026).

This direct line ensures you receive accurate and up-to-date information specific to your situation.
