| Certifications | The Australian CEC approved-inverter export dated 22 July 2026 lists exact IS-HYB-5000-3PH and IS-HYB-6000-3PH models to AS/NZS 4777.2:2020 through 9 May 2027., The exact datasheet lists IEC 62109-1/-2 and AS/NZS 4777.2:2020. | 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. |
| Warranty scope | Australia; iStore's March 2026 terms explicitly name IS-HYB-5000-3PH and IS-HYB-6000-3PH and provide a 120-month inverter warranty. Accepted-return freight is covered and any installer rebate remains discretionary. | 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. |
| Warranty remedy | Repair, replacement or credit at iStore's option. | Deye may repair or replace using new or reconditioned parts or products. |
| Labour and reinstallation | The fixed installer rebate is discretionary and is not full labour cover. Removal and reinstallation costs are not promised in full. | Repair labour applies in years one to five; uninstalling and reinstalling are excluded. Labour is excluded in years six to ten. Excluded. |
| Freight | Return postage is covered after an accepted claim. | Non-expedited shipment from Deye within Australia and New Zealand is covered; transport damage and broader freight are excluded or not stated. |
| Transfer and registration | No express subsequent-owner transfer right was found in the governing terms. Any promotional extension is subject to its published promotion and may be parts-only. | 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. |
| Grid compatibility | Three-phase 230/400 V family with Australian Region A, B and C grid profiles documented and exact-model CEC listings. DNSP settings and export limits remain installation-specific. | Single-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. |

| Review note | In Australian purchasing comparisons this product is listed under iStore, the local brand and warranty counterparty. iStore documents a strategic manufacturing partnership with Huawei and continuity for installed Huawei systems. | 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. |

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.
