| Certifications | The current Australian approved-inverter export lists FOXESS KH10.5 (AS4777-2 2020) from 13 June 2025 to 13 June 2028. | The exact Australian datasheet publishes IEC 62109 and AS/NZS 4777.2 compliance. |
| Warranty scope | FoxESS Australia's inverter warranty names KH7, KH8, KH9, KH9.9, KH10 and KH10.5 and provides 120 months from installation, capped at 132 months from manufacture. Annual authorised inspection is required from year six and service or transport rebates are conditional. | Australia; GoodWe's standard terms provide five years of full inverter cover plus a further five years of replacement-parts cover for eligible DNS G3 units, subject to registration and terms. |
| Warranty remedy | FoxESS may repair or replace an approved defective product under the governing terms. | Repair, parts supply or replacement at GoodWe's option. |
| Labour and reinstallation | The warranty does not establish an uncapped owner-selected labour entitlement; approved service is subject to FoxESS processes and limits. No uncapped removal and reinstallation entitlement was established in the governing terms. | Service rebates are conditional and not full-term labour cover. Removal and reinstallation are not an unconditional entitlement. |
| Freight | Transport support is subject to the governing claim process and exclusions; no uncapped transport entitlement is stated. | Ground freight is conditional and capped. |
| Transfer and registration | No express subsequent-owner transfer right was found in the governing Australian inverter warranty. The claim must satisfy the warranty's purchase, installation, evidence and notification requirements. | No subsequent-owner transfer right was found in the governing terms. The further five-year parts period requires eligible installation, registration and SEMS connection. |
| Grid compatibility | The exact KH10.5 is approved to AS/NZS 4777.2:2020. DNSP export and interoperability settings remain installation-specific; AusNet also lists the exact model in its interoperable inverter register. | Single-phase 230 V Australian string-inverter family with AS/NZS 4777.2 compliance. |

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.
