| Certifications | The CER export last modified 10 August 2026 lists exact 7, 7.6, 8 and 10 kW AU-AM2-P codes through 20 July 2029., The exact Australian datasheet names AS/NZS 4777.2 and IEC/EN 62109-1/-2. | The CER export last modified 10 August 2026 lists all six exact Verto Plus models through 19 June 2029., The exact Australian datasheet names IEC 62109-1/-2 and applicable national grid standards. |
| Warranty scope | Deye warranty Version 2.16 covers all SUN-series AU-type hybrid inverters and explicitly includes the 7, 7.6, 8 and 10 kW SG05LP1-AU-AM2-P pattern for ten years, with narrower coverage in years six to ten. | Fronius International Limited Warranty EN_0326 applies to Fronius inverters purchased on or after 1 June 2026. Australia receives five years Warranty Plus without registration and a total of ten years after eligible Solar.web registration within 30 months of ex-works delivery. |
| Warranty remedy | Deye may repair or replace using new or reconditioned parts or products. | Fronius may repair, replace with an equivalent or newer product, or issue a current-value credit when repair or replacement is unavailable. |
| Labour and reinstallation | Repair labour applies in years one to five; uninstalling and reinstalling are excluded. Labour is excluded in years six to ten. Excluded. | Warranty Plus covers authorised labour directly associated with removal and replacement; unauthorised costs are excluded. Covered only when performed by Fronius or a specialist installer commissioned by Fronius. |
| Freight | Non-expedited shipment from Deye within Australia and New Zealand is covered; transport damage and broader freight are excluded or not stated. | Standard national shipping is covered; express, air or sea transport, customs and export certificates are excluded. |
| Transfer and registration | No automatic subsequent-owner transfer right is stated. No pre-registration condition is stated. Claims require serial, invoice, system and fault evidence and must be made within one month after failure. | Existing warranty rights transfer with ownership without restarting or expanding the term. Five years applies without registration; the free extension to ten years requires eligible Solar.web registration within 30 months of ex-works delivery. |

| Review note | SUN-10K-SG05LP1-AU-AM2-P is listed at 10 kW in the current CER export. External switching and battery requirements remain outside this independent inverter record. | Verto 33.3 Plus is the highest exact model. Full Backup requires external grid-switchover equipment and project-specific electrical design; no external equipment selection is made here. |

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.
