| 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 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 | 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. | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. |
| 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. | 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 | 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 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 | 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. | The exact 9.3 kWh battery module and supported stacks are current Australian approved-battery entries. |
| Register: parts term | Not in the structured register | stated: Ten-year product warranty for the named SMILE-G3-S5 system when installed on or after 1 November 2024. |
| Register: labour and service | Not in the structured register | excluded: Normal maintenance, installer costs, travel and accommodation for on-site support are excluded. No general site-labour reimbursement is promised. |
| Register: transport and freight | Not in the structured register | conditional: Replacement parts and freight are included for valid claims, but other transport, travel and accommodation costs are excluded and reimbursement requires documentary evidence. |
| Register: registration | Not in the structured register | conditional: Installation requires an SAA-accredited installer with a valid Alpha Installer ID, and the serial number must be registered before a warranty claim. |
| Register: transferability | Not in the structured register | stated: The warranty transfers to a subsequent purchaser of the building or products while the products remain installed and all warranty conditions continue to be met. |

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.
