| Certifications | The current Australian approved-inverter list names all seven X3-HYB-P models from 4 kW to 15 kW under certificate AZ 69028775, approved 1 May 2026 and expiring 1 May 2029., The exact Australian datasheet lists IEC 62109-1/-2, AS/NZS 4777, VDE-AR-N 4105, G98/G99, EN 50549 and CEI 0-21. | 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 | SolaX's Australian Version 1.6 warranty explicitly names X3-HYB-4.0/5.0/6.0/8.0/10.0/12.0/15.0-P for 10 years, subject to authorised supply, installation, activation and registration. The remedy is at SolaX's option and normal ground transport is capped at AUD 200 per case. | 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 | Software correction, repair on or off site, or an equivalent replacement at SolaX's option. | Deye may repair or replace using new or reconditioned parts or products. |
| Labour and reinstallation | The policy permits on-site repair but does not promise an unlimited owner entitlement to third-party site labour. Full removal and reinstallation cost is not stated as an unconditional entitlement. | Repair labour applies in years one to five; uninstalling and reinstalling are excluded. Labour is excluded in years six to ten. Excluded. |
| Freight | Normal ground transport is covered in specified Australian areas up to AUD 200 per case; excess cost remains with the claimant. | 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 automatic subsequent-owner transfer right was found in the governing terms. Authorised supply, installation, activation and SolaXCloud warranty registration are required by the governing terms. | 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 220/380 V or 230/400 V hybrid family with exact Australian approved-list entries. The 5, 10 and 15 kW models are listed at 4,999 W, 9,999 W and 14,999 W respectively for AS/NZS 4777. DNSP acceptance remains site-specific. | Single-phase Australian identity.

| Review note | The manual names multiple SolaX high-voltage battery systems, but inverter compatibility alone does not establish current Australian battery approval, rebate eligibility or local availability for every configuration. Those checks remain outside this inverter record. | 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.
