What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Usable capacity
Stated depth of discharge: 95%. Published usable energy: 14.59 kWh in the scored configuration. These values may have different measurement conditions.14.59 kWh usableScored configuration: Cygni 10.0HS-M4. Published range 7.3–43.77 kWh.
The stated depth of discharge and published usable energy can have different test conditions or configuration limits. They do not by themselves establish nominal capacity or a reserve that is always inaccessible. Delivered AC energy and runtime also depend on the inverter, settings and loads.
The score is fixed to 10.0HS-M4. M6-M12 power, backup and integration claims do not transfer to the scored reference.
Usable capacity sourceDepth-of-discharge source 1Depth-of-discharge source 2Capacity guarantee: minimum retained at year 10
No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

Strong evidence coverage
18 of 18 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them. How the evidence puzzle works
Record revision. Exact Cygni Australian datasheet, manual and V2-2025 governing warranty reviewed 2026-08-06. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged. T6 United States first-market overlay review 2026-09-04: official United States catalogues recorded; Australian and German overlays and scores unchanged. Exact Australian Cygni warranty depth reviewed 4 October 2026: the AU download centre still links the Australia-labelled V2-2025 instrument naming Cygni 10.0HS-M4. Cover starts at first completed installation or 180 days after Dyness shipment, whichever is earlier. Battery/inverter ten-year terms are separate from meter three years, Wi-Fi five years and LCD two years; accessories/toolkit are excluded. Used without communications, the policy reduces the term to three years, but does not define this as continuous Internet/cloud connectivity. The required link and outage tolerance remain unestablished. Replacement retains the original remaining term. The policy requires defect notice within 48 hours and separately excludes failures not reported within two weeks; those are distinct clauses, not an extended notice period. Unregistered owners can submit the warranty card by email/dealer, while registered owners use the app/web claim route. Jointly approved disputed testing is buyer-paid initially, with testing/transport reimbursed if the claim is valid; unconditional site labour, freight and removal/reinstallation cover remains unestablished. Relocation requires written Dyness confirmation. The warranty appendix calls for coastal installation one kilometre from the coastline, altitude below 3000 m, 0–50 C ambient and no conductive dust/corrosive gas; these are warranty conditions, not additional performance ratings or a site determination. The exact M4 minimum output throughput is 45.271 MWh, with a 70% usable-energy endpoint subject to the ten-year/throughput gate. Warranty capacity testing is at 25–30 C ambient/BMS battery temperature and 0.2C on the battery DC side, with M4 438 V CC/CV charge, 0.05C cut-off current and 336 V discharge cut-off. This is not AC round-trip efficiency or an independent cycle test. The appendix 8000-cycle statement is not used to replace the earlier time/throughput gate or manufacture a measured reliability result. Australian Consumer Law rights are preserved. The separate worldwide V2-202502 document shares these M4 terms; its filename/link date does not supersede the Australia-labelled instrument. New V3.0 manual and 20251020 sheet locators were discovered but not reviewed in this warranty batch. Approval, availability, technical claims, scored 15.36 kWh nominal/14.59 kWh usable reference and US/DE outcomes are not refreshed.

AU Warranty conditions
- Current text
- labour: Unconditional full-term site labour coverage was not established and is not credited.; registration: 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.; remedy: Repair/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.; removal reinstallation: Unconditional removal and reinstallation coverage was not established and is not credited.; transferability: An automatic transfer right was not established in the reviewed governing document.; transport: Conditional 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.

- Existing dated approval and product evidence retained. Warranty appendix requires coastal installation one kilometre from the coastline, altitude below 3000 m, ambient 0–50 C and no conductive dust/corrosive gas; these are warranty conditions, not new physical ratings. Relocation requires written Dyness confirmation. Required communications link and outage tolerance are not specified as continuous cloud access in the reviewed policy.

- Australia-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.
