| 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; the exact E1 family warranty provides a non-transferable ten-year term with a stepped 70% then 60% performance threshold, subject to throughput, monitoring and use conditions. | 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. |
| Safety notice | No model-specific notice recorded | No model-specific notice recorded |
| Review note | Growatt Australia publishes the current E1 datasheet, E1/E2 compatibility statement, manual and local service channel. | 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.
