Warranty coverage: 10-year term
Coverage includes
Parts only · 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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score uses the 40 kW highest exact Australian model. This iStore family remains separate from Huawei. Scored model: IS-INV-40000-3PH · checked 2026-08-02. Evidence.

Strong evidence coverage
22 of 22 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
- Current text
- The governing iStore PV Products Warranty and Service Conditions (as at March 2026, page 3, clause 2.1) lists IS-INV-29900-3PH and IS-INV-40000-3PH among the products it covers (page 2) and gives iStore Solar Inverters 120 months, commencing from the earlier of the 180th day after shipment from iStore or the installation date. Labour is not promised in full: a fixed $150 ex GST rebate for a replacement is offered at iStore's discretion and is subject to change without notice (pages 4 to 5). The May 2024 datasheet (page 1) describes the 10 year warranty as parts and labour and a free 2 year extension as parts only; the March 2026 conditions are silent on full labour cover and are used for the labour term.
