Half the cost of battery accreditation is funded, and enrolling first does not secure it
A $1.6 million grant program running to the end of 2027 will meet half the cost of battery training for eligible businesses. Training providers have begun promoting it to Western Australian installers on a first come, first served basis. The body administering the program describes the process differently, and the difference decides whether a business that enrols today is funded at all.

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
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.
Construction training levy threshold lifts to $100,000 while safety training funding holds
The threshold at which the Construction Training Fund levy becomes payable in Western Australia rose fivefold on 1 July 2026, the first change since 1999. What the same fund pays toward training apprentices and workers did not move with it.

Commercial solar feasibility in WA: the checks before system sizing
Commercial solar feasibility starts with interval demand, the point of connection and site constraints. Roof area and an advertised certificate value do not establish a viable system size.
Commercial solar connection pathways on the Western Power network
Commercial solar connection is a separate workstream from equipment selection. This guide distinguishes Western Power's current technical review pathway from WA reforms that remain under consultation.
WA Government Opens Consultation on Solar, Battery and EV Charger Connections
The WA Government has published an issues paper with seven proposals to improve data quality and connection timeframes for solar, batteries and EV chargers on the SWIS.
Market Commentary
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.
The Battery Market Slowdown Is Partly a Reporting Lag
Battery registrations fell sharply after the 1 May certificate changes. Part of that fall is a reporting artefact, because installers have twelve months to create certificates and recent months are always incomplete when first published.
Announced 1 MW Commercial Solar Rebate Cap
The Commonwealth will lift the Small-scale Renewable Energy Scheme's maximum eligible system size tenfold, from 100 kW to 1 MW. The change is scheduled for 1 October and remains subject to regulation.
