Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 24 of 95 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

Strong evidence coverage
27 of 27 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.

AU Warranty scope
- Before
- Australia; Huawei's Australian SUN2000 warranty and service conditions provide a 10-year standard warranty for eligible residential L1 inverters, subject to the published terms.
- After
- Australia; Huawei Technologies (Australia) Pty Ltd's SUN2000 Warranty and Service Conditions list SUN2000-2/3/4/4.6/5/6KTL-L1 and state a 120-month warranty period (years 1 to 10), commencing on the 180th day after shipment from the Huawei factory or on the installation date, whichever is earlier. The document prints no revision number.
AU Support Note
- Current text
- SolarQuotes reports that, as of February 2024, Huawei solar inverters are no longer sold in Australia under the Huawei name. iStore's notice of 21 March 2024 states that Huawei remains in the market to support Huawei-branded products installed to date and honour active warranties, and invites future business enquiries to iStore. The approved-inverter list published by the Clean Energy Regulator shows the listing for SUN2000-5KTL-L1 expired on 31 December 2025 (list modified 24 September 2026). Huawei's Australian website still listed the SUN2000-5/6KTL-L1 product and specification pages on 7 October 2026, and no Huawei notice of the sales change was located.

US Support Note
- Current text
- Huawei adjusted its US solar inverter business in June 2019 amid US-China trade tensions. In a statement reported by PV Tech on 27 June 2019, Huawei said it retained a basic sales and after-sales service team and that its products could still be purchased through distributor channels; the same report attributes accounts of staff being laid off or reassigned and of new orders stopping to an investor note from ROTH Capital, not to Huawei. The region selector on Huawei's global FusionSolar site listed no United States or North America region on 7 October 2026. The exact SKU "SUN2000-5KTL-L1" is an international single-phase 220/230/240 V model, and its published standards list, which Huawei headed "More Available Upon Request", names no US interconnection standard (UL 1741 or IEEE 1547). The unavailability finding here rests on Huawei's 2019 reduction of its US business, the absence of a US region on Huawei's global site and the absence of a US interconnection standard in the exact product's published standards list, not on a solar-specific ban.
