| Certifications | BAT-521 lists B500 at 4.96 kWh nominal and 4.46 kWh usable, approved 27 May 2024 and expiring 27 May 2027., EESS-230794-1 lists EP760, approved 29 April 2024 and expiring 29 April 2027. | 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. |
| Warranty scope | Ten years or the configuration throughput cap, whichever occurs first, with a 70% retained-capacity endpoint. | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. |
| Warranty remedy | Repair, replacement or another remedy is provided at BLUETTI's discretion under the governing terms. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Unconditional full-term site labour coverage was not established and is not credited. Removal and reinstallation are not treated as an unconditional entitlement. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Valid-claim logistics are addressed by the warranty, but unconditional coverage of every transport cost is not credited. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | An automatic transfer right was not established in the reviewed governing document. Certified installation and notice within 30 days of discovering a fault are stated claim conditions. | Transfers automatically with the building while the system remains installed; ownership evidence may be required. Initial serial registration and eligible installation are required. |
| Grid compatibility | Single-phase EP760 hybrid inverter with exact Australian approval. DNSP settings, export limits and backed circuits remain site-specific. | 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. |
| Local product pathway | No separate local pathway recorded | No separate local pathway recorded |
| 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 | This record includes EP760 with two to four B500 modules only. B500A, one-module, five-module, six-module, VPP and generator claims are outside the exact reviewed boundary. | The exact 9.3 kWh battery module and supported stacks are current Australian approved-battery entries. |

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.
