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: 96.7%. Published usable energy: 5.8 kWh in the scored configuration. These values may have different measurement conditions.5.8 kWh usableScored configuration: GW6.0-BAT-D-G20. Published range 5.8–8.7 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 5.8 kWh technical base unit is scored; CER's 5.9 and 8.85 kWh values remain regulator declarations.
Usable capacity sourceDepth-of-discharge sourceCapacity guarantee: minimum retained at year 5
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.

AU Support Note
- Current text
- The score uses the 5.8 kWh GW6 technical configuration. CER records 5.9 kWh usable for GW6 and 8.85 kWh for GW9; the manufacturer sheet records 5.8 and 8.7 kWh. The two source classes are displayed separately. Regional warranty Appendix A uses 25±2 C after at least twelve hours storage, 0.2P charge/discharge to cell cut-off, thirty-minute rests and the third discharge capacity. Its printed repeat-steps instruction is retained as written, not silently repaired. Throughput simulation assumes 10–25 C, at most one cycle/day and discharge current at most 50 A; these warranty conditions do not replace the datasheet beginning-of-life capacity or cycle-test protocol.

- Current text
- labour: Conditional discretionary on-site rebate, subject to prior site-visit authorisation, confirmed covered defect and return, eligible service provider, application within two months of authorisation and a per-case cap including GST. Rate is not published in this policy; site labour reimbursement remains subject to these limits.; registration: Original purchase proof, model/serial and installation/failure information are required. No separate mandatory online registration found in this reviewed policy. Install within six months of production; qualified installation/manual and storage requirements apply. Report failure within two weeks; claim instructions also state one month from failure, so retain both deadlines and report promptly.; remedy: GoodWe chooses configuration/software correction, repair or new/refurbished equivalent-or-better replacement. Obtain RMA confirmation before replacement. The default limited remedy covers hardware materials; statutory consumer rights remain additional.; removal reinstallation: No unconditional full removal/reinstallation reimbursement is established. Hardware remedy and possible capped authorised service rebate apply; ask for approval and cost responsibility before replacement. Statutory rights remain additional.; transferability: The reviewed AU/NZ policy does not establish unconditional transfer to a subsequent owner. Remaining warranty transfers to an authorised replacement unit, with a six-month minimum if less time remains; this is not owner transfer.; transport: Conditional capped normal-ground inbound/outbound support in some areas; rate requires confirmation. Claimant pays excess or alternative-method costs and may need to organise return. Confirm shipment in advance; return within four weeks of receiving replacement, or replacement/delivery/service charges may apply.

- Current text
- AU/NZ Rev 1.1 (17 September 2026) names GW6.0-BAT-D-G20 and GW9.0-BAT-D-G20. GoodWe Technologies Co., Ltd is the warrantor; GoodWe Australia Pty Ltd is the Australian importer. For authorised-channel units sold and installed after October 2024 in AU/NZ, product hardware and performance warranties are each ten years. Commencement is original end-user purchase; without adequate purchase documentation, the earlier of installation or six months after manufacture applies. Performance is 70% of usable energy or 3.0 MWh DC throughput per usable kWh, whichever comes first. The existing five-year global product-warranty assessment is retained separately and does not describe this regional entitlement. Statutory rights remain additional.
