Knowledge base · Decision evidence

Five questions the headline specification cannot answer.

A living reference for backup operation, digital control, battery behaviour, panel durability and the Australian service pathway across 104 buyer-ready products.

From brochure claim to decision record

The difficult questions need their own evidence state.

Each lens reads existing criterion-level provenance. Published evidence means the record carries a direct or derived source. Reviewed absence means an exact document was checked but did not publish the qualifying detail. Open means the question is not yet established.

Australian buyer-ready cohort

Follow the evidence behind the decision.

The five lenses rebuild from the current product records. A reviewed absence means the exact source was checked and did not publish the qualifying detail.

Buying question

What continues operating, at what output, through which hardware, and under which phase and duration limits?

Evidence boundary

A published backup capability is not a site design. Protected circuits, phase balance, motor starts and network requirements remain installation-specific.

Research contract

A missing disclosure is recorded, not repaired with an assumption.

Exact scope. Product, model family, market and document scope must align before a claim is attached.

Primary evidence. Manufacturer manuals, governing warranty terms, certification bodies and regulators lead the record.

No system approval. Product behaviour does not establish array design, equipment selection, network acceptance or installation compliance.

Living counts. New products and stronger documents update this page on the next benchmark build.

Service-pathway coverage records what Australian warranty documents promise. It does not score actual response quality, claim speed or replacement-stock availability unless those outcomes are independently established.
