The data
Hybrid inverter
Manages PV, battery DC and household AC through the inverter platform.
- Product role
- The battery remains a separate product even when it belongs to the same branded platform.
- Published range

What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 24 of 93 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.

Market context
Global evidencechange in the site menu
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 is anchored to KH10.5, the highest rated hybrid model in the Australian KH 7 to 10.5 kW series. The KA AC-coupled sibling is not included. Scored model: KH10.5 · checked 2026-07-27. Evidence.
Sources & references · checked 2026-08-30
Strong evidence coverage
26 of 26 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.

- A leftover German KH/KA datasheet names KH10.5. The live German hybrid catalogue cards show H1/AC1, H3 Smart, H3-M, H3 PRO and H3 Plus, not KH. The AU-style /35 product URL returns 404. Remaining-stock availability is not inferred from a leftover datasheet.
