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 uses SG320HX-20, the only exact bin on the V8 sheet linked from Sungrow India's SG320-350HX-20 card. SG350HX-20 is not transferred from the URL slug. Scored model: SG320HX-20 · checked 2026-09-03. Evidence.

Strong evidence coverage

24 of 24 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.

    IN Support Note

    Current text
    Listed on Sungrow India's string-inverter catalogue card SG320HX-20, which links to the product page at the URL slug sg320-350hx-20. The official V8 datasheet linked from that page names SG320HX-20 only. India has no public per-model BIS register, so registration is not independently verified here. Manufacturer listing is established; distributor inventory is not inferred. SG350HX-20 is not transferred from the URL slug.
