| Certifications | The CER export last modified 10 August 2026 lists exact H3-Pro-15.0 through 21 January 2029., The current Australian datasheet and manual identify H3-Pro-15.0 as a three-phase storage inverter. | The current Australian approved-inverter export lists FOXESS KH10.5 (AS4777-2 2020) from 13 June 2025 to 13 June 2028. |
| Warranty scope | The current Australian warranty expressly includes H3-Pro-15.0. The standard term is 120 months from installation, capped at 132 months after manufacture. Conditional service-rebate and transport provisions do not establish unrestricted labour or freight cover. | 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. |
| Warranty remedy | FoxESS may repair onsite or at a service centre, or replace with the closest current product. | FoxESS may repair or replace an approved defective product under the governing terms. |
| Labour and reinstallation | An installer service rebate may be approved, but its amount and eligible work are not stated; travel, onsite installation, modification and maintenance are excluded. Unrestricted removal and reinstallation cover is not stated. | 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. |
| Freight | Eligible road transport to one specified address may be provided; express and onward shipping are excluded. | Transport support is subject to the governing claim process and exclusions; no uncapped transport entitlement is stated. |
| Transfer and registration | No automatic subsequent-owner transfer right is stated. Registration is recommended for standard cover and required for FoxPlus; the FoxPlus section contains a conflicting 72-month standard-period reference. | 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. |
| Grid/network approval evidence | Three-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. | 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. |

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.
