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.
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.
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.

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.
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.

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.
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.
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.
