| Certifications | The exact Australian S2 datasheet publishes IEC 62040, IEC 62477, IEC 62619, CE, RCM, VDE2510-50, UKCA and UN 38.3 compliance. IECEE CB test certificate JPTUV-183955, issued by TUV Rheinland Japan on 12 February 2026, records conformity to IEC 62619:2022 and lists APX 10.0P-S2 AU. TUV Rheinland certificate R 50711063 0001 records testing to IEC 62477-1, IEC 62040-1 and AS 62040.1:2019 and lists the same model., The CER approved-battery export last modified 24 September 2026 lists APX 10.0P-S2 AU, with the 5.0, 15.0, 20.0, 25.0 and 30.0 kWh S2 AU sizes, under Shenzhen Growatt New Energy Co Ltd, approved 23 April 2026 and expiring 31 December 2027. The older S2 rows without the AU suffix are separate identities, approved 30 November 2023 and expiring 30 November 2026, and are not transferred to this record. | 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 APX warranty publishes a 10-year non-transferable term, with 70% retained capacity for the first five years and 50% through year 10, subject to operating and monitoring conditions. The term runs from the customer purchase date and ends no more than 10 years and 3 months after delivery from Growatt. | 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 | Growatt chooses repair, onsite repair or an equivalent-value replacement based on model and age. Repair or replacement retains the remaining original warranty period. During the latter five years, the instrument also allows pro-rata buyback or newer technology at a price payable by the customer. Australian Consumer Law guarantees are expressly preserved. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Contractual labour and compensation exclusions are subject to statutory liability and the instrument’s preserved Australian Consumer Law guarantees. Removal and reinstallation are excluded. | Clause 2 excludes travelling and accommodation costs of persons for on-site support and does not name labour as covered or excluded. The warranty requires a qualified installer to be available for exchange and re-commissioning (clause 3) and obliges the original installer to assist with replacement (clause 10); reimbursement of necessary and reasonably incurred costs of a valid claim may be claimed with documentary evidence (clauses 2 and 10). Removal and reinstallation are not promised. |
| Freight | Contractual logistics-cost exclusions are subject to statutory liability and the instrument’s preserved Australian Consumer Law guarantees. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | The governing Australian warranty states that it is non-transferable. Growatt-platform monitoring of the battery and charge/discharge device is required; the instrument reduces cover to three years without monitoring. Installation must finish within six months of Growatt delivery. Notify the supplier within 14 days of problem signs and submit the claim form within one month of failure, with original warranty card, purchase/installation invoices and signed commissioning report. Accumulated-discharge evidence is required for performance claims; an unmonitored claim requires qualified onsite inspection/data collection. | 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 | High-voltage DC battery for compatible Growatt three-phase hybrid inverters; backup performance depends on the paired inverter. | 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 | Growatt Australia publishes the exact APX HV S2 AU series. | 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.
