Installer Bulletin: NEOVOLT Batteries Face CEC Suspension from 15 September
The Clean Energy Council has notified industry of an intended suspension of seven Bytewatt NEOVOLT battery models over certification and labelling matters.
Installer Bulletin: General Electrical Work in a Home That Already Has a Battery
Electrical Contractors Association WA reports an increasing number of technical enquiries about battery systems encountered during ordinary residential work. A job booked as a power point, a light or an EV charger now regularly involves an installation with a battery energy storage system the attending electrician did not install, and that changes both the isolation procedure and the testing that has to follow.
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.
Market Commentary
WA's Capacity Price Benchmark Moves Back to a Gas Turbine
The Coordinator of Energy published a Draft Determination on 9 September 2026 proposing an E-Class simple cycle gas turbine as the benchmark technology behind both of Western Australia's capacity prices. A battery held that reference until a duration rule moved from six hours to seven.
Battery Sizing Fragmented After the 1 May Capacity Taper
Analysis published on 7 September 2026 records the size that dominated Australian battery installations in April losing most of its market within a month of the federal capacity taper starting. By July no single size held more than about five per cent, and the quarterly average fell about a tenth.
Australia Has Entered the Retrofit Stage of the Home Battery Market
A market-stage framework published on 31 August 2026 places Australia in the retrofit stage, where battery-only installations have climbed from under a tenth of the market to around 40 per cent and batteries now outnumber new solar systems. The stage draws on a finite pool of existing rooftops.
Compliance & Safety
Regulator Suspends a Provider Over Digitally Altered Installation Photographs
Victoria's Essential Services Commission suspended an accredited provider on 25 August 2026 after its fraud taskforce identified markers indicating that photographs submitted as evidence of completed upgrades had been digitally altered. The scheme does not operate in Western Australia, but the detection method transfers directly to certificate evidence lodged here.
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.

ACCC grants the NETCC five years, amended code from 19 December
The New Energy Tech Consumer Code has been reauthorised by the Australian Competition and Consumer Commission. The determination closes a process that ran for two years, grants five years with conditions, and puts a date on the switch to the amended code.
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.
