The assessment
How it scores, by category
Market position
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
- 6–9.9 kW
- Phase
- Three phase
- Backup boundary
- Not recorded
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.

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 uses the named exact German benchmark; larger stacks, paid states and nearby generations do not transfer evidence. Scored model: Power Storage DC 10.0 · checked 2026-08-16. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
13 of 13 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.
Record revision. July 2025 German datasheet, current certificates and warranty checked 2026-08-16. First-market US overlay review 2026-09-01: official United States catalogues recorded; existing Australian and German overlays and scores unchanged.
