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 highest exact current power bin named on the V14 sheet linked from Sungrow India's SG4.0-5.0-6.0RS-L card. SG10RS is a different identity. Scored model: SG6.0RS-L · checked 2026-09-03. Evidence.

Strong evidence coverage

25 of 25 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 Warranty scope

    Current text
    India; the India manufacturer warranty HTML on sungrowpower.com/in/en, with the 2.3 product-list image, lists Residential Inverter (1-phase and 3-phase) at 5 years standard, with paid extension to 10 years. The instrument does not name SG6.0RS-L. Six structured warranty terms are recovered from clauses 3, 6 and 7 of that India HTML. AU, US or DE terms are not transferred.

    labour: Sungrow does not bear labour costs for removing the defective product or reinstalling the repaired or replacement product. In-warranty cover is materials only (clause 7.3).; registration: No baseline pre-install registration deadline is stated. Cover starts from the invoice date or documented first installation, or six months after Sungrow factory shipment if both documents are missing. Claims need proof of purchase, serial number and a defect report via phone, email or Sungrow GSP (clauses 2.2, 6.1 and 6.2).; remedy: Sungrow supplies the materials needed for repair (replacement parts or an equivalent replacement). If the product is not repairable, Sungrow may supply a new or refurbished replacement of equal or higher performance. Remaining term follows the replacement (clauses 3.1 and 3.3).; removal reinstallation: Sungrow does not cover removal, reinstallation, or troubleshooting of other electrical-system components. Relocation to a new site needs Sungrow's written consent and a paid on-site inspection (clauses 3.7, 5.1(j), 7.3 and 7.4).; transferability: Warranty rights may transfer to a later owner, authorised operator or lessee at the same site during the warranty period. The new end-user must sign and submit Sungrow's warranty transfer agreement (clause 3.6).; transport: The claimant bears freight of the alleged defective product back to Sungrow. Sungrow bears freight of the new or refurbished product to the end-user. Shipping damage is excluded (clauses 7.1 to 7.3).
