| Certifications | The current Australian lists name X1-P6K-S at 6,000 VA through 11 July 2028 and the exact X1-P6K-B10-S scored system at 10 kWh usable under BAT-548 through 4 October 2027., The exact battery configuration publishes IEC 62619 and the exact hybrid power modules publish AS/NZS 4777.2 and IEC 62109-family safety compliance., The current CSIP-AUS register identifies an Anker SOLIX Aggregator pathway for the approved X1 inverter family. | 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 AC system code receives 10-year terms. Battery coverage ends at 10 years or 2.8 MWh discharged per nominal kWh, whichever comes first, with 70% retained capacity. | The exact Australian datasheet publishes 10-year product and battery-performance warranties, governed by current AlphaESS Australia terms and Australian Consumer Law. |
| Warranty remedy | Replacement parts or replacement units, which may be refurbished or functionally equivalent; refund is reserved for limited circumstances stated in the policy. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | Dismantling, installation and troubleshooting costs are excluded. Dismantling, reinstallation and moving the device to a new location are excluded. | Installer travel and on-site labour are excluded. Removal and reinstallation are not promised. |
| Freight | Anker supplies return instructions and delivers a repaired or replacement product in the original country; buyer-arranged transport damage is excluded. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | The policy is restricted to the original country of purchase and does not publish an automatic transfer right for a later property owner. Proof of purchase, serial number and defect evidence are required. The policy applies to direct or authorised-reseller purchases and the claim must proceed through Anker's documented process. | 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 | Single-phase AC-coupled 10 kWh scored configuration with 6 kW output. Power Dock Pro is required for the current third-party off-grid solar recharge pathway. Backed circuits and transfer behaviour remain design-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. |

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.
