Labour and reinstallation	Unconditional full-term site labour coverage was not established and is not credited. Unconditional removal and reinstallation coverage was not established and is not credited.	Installer travel and on-site labour are excluded. Removal and reinstallation are not promised.
Freight	Unconditional full-term transport coverage was not established and is not credited.	Replacement-parts freight is covered for an accepted claim.
Transfer and registration	An automatic transfer right was not established in the reviewed governing document. Continuous communications are required; without communications the published warranty term reduces to three years.	The warranty is non-transferable except where the products remain installed in a building, in which case it transfers to a later purchaser of that building. Serial registration before a claim, and installation by an SAA-accredited installer with a valid Alpha Installer ID, are required.
Grid/network approval evidence	Single-phase integrated hybrid family with exact Australian approval entries. DNSP settings and export limits remain site-specific.

Australia purchase checks

Make the shortlist quote-ready

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.

Lock the exact model and installation-date listing.
Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.
Obtain the site-specific connection settings.
Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.
Test savings against the household, not a brochure.
Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.
Specify the operating outcome.
Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.
Name the party responsible after installation.
Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
