ACCC grants the NETCC five years, amended code from 19 December

Installer bulletin: CSIP-AUS registration for Powerwall 3 in WA
Guidance current at 14 August 2026 states that AC-coupled Powerwall 3 configurations are not supported in any capacity. Two pathways remain: new solar wired directly to the integrated inverter, or migration of suitable existing PV onto it. This bulletin sets out those pathways, the CSIP-AUS registration process, the export limit position, and the two failures behind most registration problems on site.
Installer Bulletin: Powerwall 2 Recall Now Routes Replacements Through the Original Installer
The Australian Competition and Consumer Commission updated recall PRA 2025/20611 for the Tesla Powerwall 2 on 12 August 2026. The notice now directs owners of affected systems to contact their original installer to schedule the free replacement, with Tesla support as the fallback. The affected units and the underlying hazard are unchanged.
Installer Bulletin: What the CER's Battery Inspections Are Failing
The Clean Energy Regulator reported results for 2,642 solar battery inspections finalised by 8 June 2026, with recurring installation findings.
Compliance & Safety
WA Opens Consultation on New Protections for Single Property Network Customers
Energy Policy WA has opened consultation on a draft Code of Practice extending customer protections to single property networks, the term now used for what were previously called embedded networks. Feedback closes 25 September 2026, ahead of registration with the Economic Regulation Authority from 1 July 2027.
Multi-state investigations test what consumer code compliance can enforce
A solar retailer expelled from the New Energy Tech Consumer Code in December 2025 continued trading and is now the subject of investigations in three states and by the Clean Energy Regulator. The sequence sets out plainly what expulsion from the code does and does not do, and why Western Australia is the exception.
First independent review of the NETCC sets ten priorities for consumer protection standards
The New Energy Tech Consumer Code has been reviewed independently for the first time since it began. The review finds a code that works in principle, carries more weight than its original mandate anticipated, and is constrained by the governance built for a smaller scheme.
Market Commentary
WA builds its own solar recycling market as the national pilot sits idle
Western Australia has committed $13 million to establish end-of-life solar collection and recycling pathways under Remade in WA, and the Department of Water and Environmental Regulation has commissioned the Smart Energy Council to run the stakeholder engagement that will shape it. Installers can contribute until 9 September 2026. The national pilot the state work would otherwise have followed has been suspended since May.
Synergy opens applications for the WA third party aggregation market
Synergy has opened the first application round for Aggregator Panel membership under Western Australia's Third Party Aggregation Framework. Panel membership is the entry condition for any organisation that wants to build market services on the batteries and solar systems of households and small businesses in the South West Interconnected System.
Cheaper Home Batteries passes 500,000 installations
The Australian Government announced on 14 August 2026 that more than 500,000 batteries have been installed under the Cheaper Home Batteries Program. The accredited installer base has doubled to 8,846 since the program commenced, which is the figure with the most direct bearing on how the market behaves from here.

Sigenergy releases a thermal insulation board for SigenStack packs, and places Australia in the optional band
Sigenergy issued a product release notice on 21 August 2026 introducing an optional thermal insulation board that snaps around individual SigenStack battery packs to cut heat loss and reduce heating pad consumption. It releases on 15 September 2026. The notice sets its guidance by latitude rather than by market, which places Western Australia across two different bands.
Sigenergy adds a DC combiner box and changes the battery controller codes
Sigenergy issued a product release notice on 18 August 2026 introducing the SigenStack BC CMB-4, a DC combiner box that connects up to four SigenStack Battery Controllers in parallel to a single commercial and industrial hybrid inverter. It releases on 30 September 2026. The same notice records a product code transition for the battery controllers themselves, and the existing controller models are not compatible with the combiner box.
SigenStack BC cable now offered in an 8m length
Sigenergy issued a product change notice on 13 August 2026 introducing an 8m SigenStack BC cable kit alongside the existing 4m version. The longer kit carries the same electrical specification and connection types, and is scheduled for release on 30 August 2026. It removes a layout constraint on commercial and industrial installations where the battery controller and the inverter cannot be positioned close together.
