| Certifications | The exact system datasheet publishes AS/NZS 4777.2 and IEC 62109 inverter compliance., The exact HM5/HM6 maker sheet, including the HM6-10 (10.24 kWh) column, lists battery IEC 62619:2022 and inverter IEC 62109-1 and IEC 62109-2 (manufacturer-declared; no test certificate retrieved). | The exact BAT-10.1P datasheet lists IEC 62619, IEC 63056, IEC 62040 and UN 38.3; the SMILE-G3-S5 AU system datasheet lists AS 4777.2 and IEC 62109. |
| Warranty scope | Australia only; ESY SUNHOME AUSTRALIA PTY LTD provides the exact HM6/10.24 kWh warranty. 120 months from initial installation, 70% available capacity and exact 43.0 MWh/10.24 kWh throughput conditions. Original-site transfer and accepted claim reimbursement are conditional; the combined cost cap is A$180 plus GST per claim. Filename v4.5 differs from retrieved PDF metadata title v4.6/November 2025; no historical supersession inferred. | 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 remedy | Repair or replacement, potentially with refurbished goods/parts. Repaired or replaced products retain the original remaining performance warranty without extension. Accepted reasonable claim costs require documentary evidence and are capped at A$180 plus GST per claim; invalid-claim costs are allocated to the customer up to the same stated cap, subject to ACL rights. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Accepted dismantling and installation labour shares the combined A$180 plus GST per-claim cap with processing, parts and shipping; this is not an uncapped site-labour promise. Personnel travel, transport and accommodation are excluded. Accepted faulty-battery dismantling and installation shares the combined A$180 plus GST per-claim cap; no separate unlimited removal/reinstallation entitlement. | 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. |
| Freight | Accepted replacement parts/product shipping shares the combined A$180 plus GST per-claim cap. Personnel travel/transport/accommodation are excluded; documentary cost evidence is required. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | Transfer requires the product to remain at its original installation site and simultaneous transfer of ownership of both site and product. No later-owner registration deadline is specified in the reviewed policy. Commissioning requires stable Internet or 4G connection and continuous online monitoring. Network outage/faults require prompt notification and supporting photos/logs; offline claims require authorized site inspection/data collection. Report failure within ten working days and submit a claim within one month of fault diagnosis; these are separate clocks. Provide purchase, serial, installation/commissioning evidence and signed commissioning report. Installation within six months of production and first-year-only capacity expansion are warranty conditions; added modules inherit the original remaining term. | 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 230 V all-in-one hybrid system with AS/NZS 4777.2 compliance and <=20 ms backup switching. | The exact AU system is a 5 kW, 230 V single-phase hybrid under AS 4777.2. Current project approval and installer eligibility remain installation-specific. |

| Review note | ESY SUNHOME publishes the exact HM6 platform and current Australian warranty. | AlphaESS's current 2026 Australian brochure lists SMILE-G3-S5/B5 with both BAT-10.1P and BAT-9.3S. The battery options coexist; neither is presented as the formal successor to the other. |

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.
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.
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.
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.
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.
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.
A score lead is only meaningful inside this shared class or tier. Weigh it against the specification and evidence rows above before deciding.
Both products are scored in the Performance & Value class, on the same rubric weighting. Scores are not comparable across classes or tiers. Full methodology.
