Bulletin, February 2026: inverter testing and SWIS changes

Hybrid-inverter testing and planned connection changes led the February bulletin. Linked records separate historical announcements from current guidance.

The February 2026 internal bulletin covered the following topics. It is not a current testing method, connection application guide or statement of third-party status.

Hybrid-inverter testing

The bulletin summarised WA guidance for multiple-mode inverters operating in partial or complete backup mode. It referred to testing under AS/NZS 4777.1, neutral-continuity evidence and documents attached to the Notice of Completion.

The current standard, regulator guidance, exact product instructions and controlled testing procedure must be used for each installation. The bulletin does not reproduce the required test method.

SWIS connection changes

The bulletin previewed changes scheduled for 1 May 2026 involving standard connection capacity, remote disconnection and inverter compliance. That preview reflects the information available in February 2026.

Current applicants must verify the applicable pathway, equipment, settings, communications, retailer process and Western Power requirements for the proposed system.

Tesla installer recognition

The bulletin recorded Perth Solar Warehouse reaching a fifth consecutive year of Tesla Premium Certified Installer status in 2026 and referred to a 95 per cent internal audit score. It also described the status as applying to a limited share of the Australian installer network.

These are third-party programme statements for a defined period. They do not establish current status, ranking or project suitability.

Corrected installation rankings

The bulletin recorded PSW Energy as fourth in Western Australia for solar capacity and third for battery capacity in the 2025 Solaris Awards. It also noted that an earlier battery position had been corrected from second to third by the publisher.

The linked record contains the capacity, system-count and market-share figures attributed to the underlying registry-based reporting. Rankings remain dependent on the stated dataset, period and methodology.

Archive sources

The bulletin did not reproduce the Australian Standards, regulator test note, network technical documents, Tesla programme terms or the underlying certificate dataset. The linked articles provide primary references or qualified records where available. Current controlled sources and current third-party publications take precedence over this monthly index.
