| Certifications | The 4 September 2026 CER battery export still lists T-BAT H 5.8 V2, T-BAT H 11.5 V2, T-BAT H 17.3 V2 and T-BAT H 23 V2 through 22 September 2026. Nearby T-BAT H 3.0 V2, 6.0 V2, 9.0 V2 and 12.0 V2 expire 19 October 2026 and are not transferred. | 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; the current linked SolaX warranty PDF explicitly names T-BAT H 5.8 V2, 11.5 V2, 17.3 V2 and 23 V2 for 10 years. Daily self-consumption and backup are limited to 6,000 cycles with 70% retained energy at 120 months; other applications use the model-specific throughput table. | 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 | Software correction, repair on or off site, or an equivalent repaired, refurbished, upgraded or new substitute at SolaX's option. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Travel, subsistence, on-site installation, modification and normal maintenance are excluded; no uncapped third-party labour entitlement is stated. Full removal and reinstallation costs are not stated as an unconditional entitlement. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Normal ground transport in specified Australian areas is covered up to AUD 200 per case; excess and alternative transport costs remain with the claimant. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | No automatic subsequent-owner transfer right was found in the current linked terms. Authorised supply, installation, activation and registration conditions apply; claims require exact model, serial and installation evidence. Battery additions after one year require prior SolaX consent. | 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 | This record is a high-voltage DC battery family. Its AU CEC battery listing does not by itself establish an inverter pairing, backup behaviour or site acceptance. | 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 | The live Australian page still names the four V2 configurations, including scored T-BAT H 23 V2. The current downloadable datasheet remains V3 hardware and is not transferred. The listing still expires on 22 September 2026. This is a freshness recheck, not a renewal. | 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.
