| Certifications | The 29 July 2026 regulator export lists ALP 5.0L-E1 through ALP 50.0L-E1 with current approval through 31 December 2027. | 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; Growatt provides a non-transferable ten-year term with 70% for years one to five and 60% for years six to ten, subject to accumulated-energy adjustments. Monitoring is required; without it the warranty is reduced to three years. Labour and logistics are expressly excluded beyond statutory rights. | 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 | At Growatt's discretion: repair, on-site repair or exchange for an age-equivalent replacement. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Labour and other claim expenditure are expressly excluded beyond statutory rights. Removal and reinstallation are not promised and labour expenditure is excluded. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Logistics fees are expressly excluded beyond statutory rights. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | The governing E1 warranty states that it is non-transferable. Original purchase and installation evidence, monitoring and prompt notice apply. Without monitoring, the warranty is reduced to three years. | 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 Australian compatibility statement names ALP 5.0L-E1/E2 for Growatt storage inverters. The stored reciprocal path is limited to the reviewed SPH6000TL-HU-AU record; final design and DNSP requirements remain site-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. |

| Review note | ALP is a current Australian low-voltage DC battery with an official local product page and regulator listing. Its 5 kW value is battery-side power for the 10 kWh reference. AC transfer, surge and outage-PV recovery remain properties of the exact external inverter and system design. Local CAN and remote diagnosis are documented, but no offline operating guarantee or product-security disclosure is published. | 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.
