| Certifications | The current Clean Energy Regulator CSV lists HIT-12L-G3-AU, HIT-15L-G3-AU and HIT-20L-G3-AU as three separate AS4777-2 2020 rows in series HIT-(5-20)L-G3-AU., All three exact rows carry approval date 30 July 2026 and current expiry 30 July 2029. Approval status is temporal and must be rechecked before purchase or installation. | 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. |
| Warranty scope | Australia; the current governing Residential Storage Inverter warranty expressly names all three accepted HIT L G3 AU models for 10 years, subject to its installation, channel, claim and exchange conditions. | 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. |
| Warranty remedy | Hoymiles may exchange an eligible unit for the same type or an equivalent or superior replacement. If Hoymiles chooses authorised on-site repair, it covers materials, labour and removal and replacement of the affected part or device. | FoxESS may repair onsite or at a service centre, or replace with the closest current product. |
| Labour and reinstallation | The policy is expressly a product-replacement warranty. Installation, commissioning and ordinary installer labour are excluded unless Hoymiles elects and authorises on-site repair. Ordinary removal of the faulty inverter and installation or recommissioning of the replacement are excluded. They are covered only where Hoymiles itself elects authorised on-site repair. | 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. |
| Freight | For an approved exchange, Hoymiles ships the replacement to the specified customer or installer location and covers collection and return freight where return is required. Other transport and access costs remain excluded. | Eligible road transport to one specified address may be provided; express and onward shipping are excluded. |
| Transfer and registration | Transfer is allowed only while the product remains at its original installation location, with previous-owner authorisation sent to Hoymiles. The end user contacts the installer first. A claim requires product model, serial number, failure code and comment, original invoice, system details, prior claim records where applicable and an RMA. | 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. |
| Grid compatibility | Three-phase 400 V hybrid inverter family. Exact AS4777-2 2020 regulator listing is established for the three accepted model strings only. DNSP connection, export limits, protected-load design and commissioning settings remain site-specific. | Three-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. |

| Review note | Australian claims begin through the installer. Hoymiles publishes service.au@hoymiles.com and HOYMILES POWER ELECTRONICS PTY LTD at Mount Waverley, Victoria as the local contact. The warranty remains administered by Hoymiles Power Electronics Inc. | FoxESS Australia publishes the exact product family and support materials. External switching and battery requirements remain outside this independent inverter record. |
| Register: parts term | stated: Ten-year limited product warranty for the named Residential Storage Inverter models. | stated: The exact H3-Pro family receives 120 months from installation, no later than 132 months after manufacture, whichever occurs first. |
| Register: labour and service | conditional: Ordinary installer labour and replacement installation are excluded. If Hoymiles elects authorised on-site repair, it covers repair materials, labour and replacement of the affected part or device. | conditional: FoxESS may repair onsite or at a service centre, replace the product, and approve an installer service rebate. The rebate amount and eligible work are not stated, while travel, onsite installation, modification and maintenance are excluded. |
| Register: transport and freight | conditional: For an approved exchange, Hoymiles ships the replacement to the specified location and covers collection and return freight when return is required; other transport and access costs remain excluded. | conditional: Eligible road transport to one specified address may be provided. Express freight and onward shipping are excluded. |
| Register: registration | conditional: A claim requires installer contact, model, serial, fault, invoice, system and prior-claim evidence, plus the Hoymiles RMA process. | conditional: Registration is recommended for the standard term and required for FoxPlus. The policy's FoxPlus wording also refers to a 72-month standard period, which conflicts with the exact 120-month H3-Pro table. |
| Register: transferability | conditional: Transfer is allowed only while the inverter remains at the original installation location and the previous owner supplies authorisation to Hoymiles. | not stated: The policy defines purchaser, installer and end-user roles but does not state an automatic subsequent-owner transfer right. |

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.
