Warranty scopeAustralia-labelled V2-2025, still linked in the AU download centre and reviewed 4 October 2026, names Cygni 10.0HS-M4. Dyness Digital Energy Technology Co., Ltd administers the warranty; Dyness Aus Pty Ltd is the importer/local service route. Start is earlier of first completed installation or Dyness shipment plus 180 days. Battery/inverter ten years; meter three, Wi-Fi five, LCD two years; accessories/toolkit excluded. Used without communications reduces the term to three years; exact link/cloud/outage requirements are unestablished. M4 performance gate is 70% usable energy until ten years or 45.271 MWh output throughput, whichever first, under the prescribed use/test conditions.Australia; the 11 October 2024 warranty names SMILE-G3-S5 and BAT-10.1P with a ten-year term, 70% retained capacity and a 3.12 MWh/kWh throughput condition for eligible installations from 1 November 2024.
Warranty remedyRepair/replacement of accepted defective product; replacement retains the original remaining term without renewal. Jointly approved disputed testing is initially buyer-paid, with testing and transport reimbursed if the claim proves within warranty. Unconditional site labour/removal/reinstallation costs remain unestablished. The policy preserves Australian Consumer Law rights.Repair or replacement at AlphaESS's option.
Labour and reinstallationUnconditional full-term site labour coverage was not established and is not credited. Unconditional removal and reinstallation coverage was not established and is not credited.Clause 2 excludes travelling and accommodation costs of persons for on-site support and does not name labour as covered or excluded. The warranty requires a qualified installer to be available for exchange and re-commissioning (clause 3) and obliges the original installer to assist with replacement (clause 10); reimbursement of necessary and reasonably incurred costs of a valid claim may be claimed with documentary evidence (clauses 2 and 10). Removal and reinstallation are not promised.
FreightConditional reimbursement of transport/testing expenses follows a valid jointly approved disputed test. This is not an unconditional full-term transport entitlement; outside-warranty costs are buyer-paid and original packaging requirements apply.Replacement-parts freight is covered for an accepted claim.
Transfer and registrationAn automatic transfer right was not established in the reviewed governing document. No mandatory initial app/web registration is established: unregistered owners use the supplied warranty card via email/dealer; registered owners use the app/web service route. Notify Dyness within 48 hours of discovering a defect; separate exclusion concerns failure not reported to seller/authorised service partner within two weeks. Provide purchase/serial/start-date/authorised defect evidence, logs and system/fault details. Without communications the term is three years; required link and outage tolerance remain unresolved.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 evidenceSingle-phase integrated hybrid family with exact Australian approval entries.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
