| Certifications | The current regulator snapshot lists the exact 3.0, 3.7, 4.6, 5.0 and 6.0 kW H1-G2 models through 3 January 2027., Single-phase hybrid family with exact current AS/NZS 4777.2 regulator entries, IEC 62109 and multiple published national grid codes. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Australia; the current FoxESS inverter warranty explicitly names the five retained H1 G2 models for 120 months from installation, capped at 132 months from manufacture. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | FoxESS may repair or replace accepted defective hardware under the published process. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Service rebates are conditional, and annual authorised inspection is required from year six. Full removal and reinstallation cost is not promised unconditionally. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | Roadway transport rebates are conditional rather than a full-cost entitlement. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | No general subsequent-owner transfer right was found in the reviewed warranty. The term is capped from manufacture and later-year coverage depends on the stated inspection conditions. | Coverage follows the product at the original installation site when the building changes ownership. Purchase, installation and claim evidence are required. |
| Grid/network approval evidence | Single-phase hybrid family with exact current AS/NZS 4777.2 regulator entries, IEC 62109 and multiple published national grid codes. DNSP settings, export limits and final site design remain installation-specific. | The exact model or family appears in the current Australian approved-inverter export. DNSP settings, export limits and site design remain installation-specific. |

| Review note | The scored benchmark is H1-6.0-E-G2. The 2.5 kW and differently named 4.0 kW marketing rows are excluded from the current Australian record because they are absent from the exact regulator intersection. | This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published. |

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.
Confirm the proposed inverter phase, PV input design, battery pairing and export-control configuration against the final connection agreement. A suitable product can still require a different site design or control setting.
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 Inverter class, on the same rubric weighting. Scores are not comparable across classes or tiers. Full methodology.
