| Certifications | The exact family datasheet lists CEC, IEC 62619, IEC 62040, CE, UN 38.3 and VDE 2510-50. | 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; Sungrow Australia Group Pty Ltd provides ten years for the exact SBR family and 70% retained capacity. Daily self-consumption and backup have unlimited cycles; other or mixed 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 | Repair, equivalent replacement or depreciated refund at Sungrow's option. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | A standard service rebate contributes to approved repair labour; travel, subsistence and full installation costs are excluded. No unconditional removal and reinstallation entitlement is stated beyond the standard service rebate. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Standard ground freight is covered up to AUD 200 for an approved claim. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | The warranty is limited to the original purchaser or supplied end user and is otherwise non-transferable. Portal registration is encouraged; iSolarCloud monitoring and complete performance data are material warranty conditions. | 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 | SBR is a high-voltage DC battery for Sungrow-approved hybrid inverters. Inverter model, firmware, backup design and DNSP approval remain installation-specific. | 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. |

| Buyer evidence | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. |

| Review note | SBR096 is current on the CER battery export until 31 October 2026. The warranty requires iSolarCloud monitoring and performance data; incomplete data reduces the promised minimum term to four years. | 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: Ten-year battery product warranty. | Not in the structured register |
| Register: labour and service | conditional: An installer service rebate may apply to an accepted claim under Sungrow's service terms, but travel and general on-site costs are not fully covered. | Not in the structured register |
| Register: transport and freight | conditional: Approved ground freight is covered up to AUD 200; other delivery methods and excess costs require approval or remain with the claimant. | Not in the structured register |
| Register: registration | conditional: Registration and iSolarCloud performance data are material to efficient warranty administration and performance verification; the instrument does not state that portal registration alone creates the ten-year term. | 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.
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.
