What the documents establish

Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.

Usable capacity

100% of this battery’s nominal capacity is usable, 9.6 kWh in the scored configuration.

9.6 kWh usableScored configuration: SBR096. Published range 9.6–25.6 kWh.

No reserve is withheld at the stated depth of discharge.

At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.

No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.

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 the 9.6 kWh SBR096 reference configuration. The Australian series spans 9.6 to 25.6 kWh per unit and supports up to four units in parallel. Scored model: SBR096 · checked 2026-07-27. Evidence.

Sources & references · checked 2026-09-02

Strong evidence coverage

29 of 29 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. Current SBR exact-family datasheet, Australian HV Battery Limited Warranty V9.0 effective 2026-05-21, and CER battery export reviewed 2026-08-07. India existing-catalogue battery review 2026-09-02: IN overlays recorded from manufacturer Indian catalogues; scores unchanged.

    The exact scored model SBR096 is not named on Sungrow's Indian residential storage catalogue. India has no public per-model BIS register, so registration is not independently verified here. Absence from that catalogue is a listing fact, not a quality finding, and does not change the global score. That catalogue names MG5/6RL, MG8RL/MG10RL and MGL060. SBR128 and SBR160 appear only in a South Africa case study on the India For Home page. Those are different identities and are not transferred.
