| Certifications | The SMILE-M5-S datasheet publishes IEC 62109-1/-2, IEC 62477 and AS/NZS 4777.2. | 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; 10-year product and battery-performance warranty, 70% retained usable capacity and 3.12 MWh per kWh usable, subject to installation, operating and connectivity 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 remedy | Repair or replacement at AlphaESS's option. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Installer labour and recommissioning are not promised. Removal and reinstallation are not promised. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Replacement-parts freight is covered for an accepted claim. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | Transfers automatically with the building while the system remains installed; ownership evidence may be required. Initial serial registration, connectivity and eligible installation are required. | 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 5 kW hybrid system with AS/NZS 4777.2, UPS backup and Australian local support. | 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 | This is separate from the older SMILE-G3 S5 record. The scored reference uses one current 13.99 kWh module while the family also supports 5-30 kWh with 5 kWh modules. | 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. |
| Register: parts term | stated: The instrument expressly includes the SMILE-M5-S system, including hybrid inverter and batteries, and states a ten-year product warranty. | Not in the structured register |
| Register: labour and service | not stated: The original installer must assist and necessary reasonable valid-claim costs may be claimed with evidence, but the instrument does not promise general full installer labour, removal, reinstallation or recommissioning reimbursement. | Not in the structured register |
| Register: transport and freight | stated: Replacement-part or replacement-product delivery freight to the original purchaser is covered for a valid claim. Other transportation, travel and accommodation costs are excluded. | Not in the structured register |
| Register: registration | conditional: Installation and commissioning must be by a properly qualified, AlphaESS-certified installer with a valid Alpha Installer ID. The serial must be registered before a claim, and internet or mobile connectivity is required for service and monitoring subject to the outage provisions. | Not in the structured register |
| Register: transferability | stated: The warranty transfers to a subsequent purchaser of the building or products while the products remain installed and the warranty conditions continue to be met. | Not in the structured register |

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.
