| Certifications | The current Australian approved-battery export lists SMILE-G3-BAT-9.3S and stacks through six modules to 31 December 2027; the exact system datasheet publishes IEC 62619 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 | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. | 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. |

| Transfer and registration | Transfers automatically with the building while the system remains installed; ownership evidence may be required. Initial serial registration 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 | The exact S5 configuration is a 230 V single-phase hybrid system with 5 kVA backup and AS/NZS 4777.2 grid regulation; final DNSP approval remains installation-specific. | The exact AU system is a 5 kW, 230 V single-phase hybrid under AS 4777.2.

| Review note | The exact 9.3 kWh battery module and supported stacks are current Australian approved-battery entries. | 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.
