| Certifications | RCM, IEC 62619, IEC 63056, UN 38.3 | 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 | GoodWe's AU/NZ warranty names LX F6.4-H-20 through LX F28.8-H-20 and provides 10 years of product and performance cover, subject to 70% retained capacity or the model-specific throughput limit. Freight and labour support in years 1-5 is conditional; years 6-10 cover hardware materials. | 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 or replacement hardware at GoodWe's option; a replacement inherits the remaining term with a six-month minimum. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | An authorised labour rebate is discretionary and conditional in years 1-5; years 6-10 cover hardware materials only. No unconditional full-term removal or reinstallation entitlement is stated. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Normal-ground freight support is conditional and capped in years 1-5; years 6-10 do not promise freight. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | No subsequent-owner transfer right is stated. Install within six months of production, report faults within one month, maintain internet monitoring, and complete any capacity expansion within one year. | 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 | This is a high-voltage battery that GoodWe documents for use with compatible EH and ET series hybrid inverters; compatibility and backup configuration must be verified for the paired inverter. | 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. |

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.
