Usable capacity
100% of this battery’s nominal capacity is usable, 16.4 kWh in the scored configuration.16.4 kWh usableScored configuration: five HS-BM-3.28-10 modules. Published range 3.28–16.4 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.
Usable capacity sourceDepth-of-discharge sourceCapacity guarantee: minimum retained at year 10
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.
Blackout protection
52 / 100#66 of 90 batteriesWhole-home (via hybrid inverter)
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.

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 documented five-module 16.4 kWh configuration and publishes the full 3.28-16.4 kWh family range. Inverter-dependent power and backup are not assigned to the battery. Scored model: five HS-BM-3.28-10 modules · checked 2026-08-02. Evidence.
Sources & references · checked 2026-09-02
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.
Record revision. SMA Home Storage AU datasheet revised 2025-03 and Australia/New Zealand warranty effective for purchases after 2025-07-14. India existing-catalogue battery review 2026-09-02: IN overlays recorded from manufacturer Indian catalogues; scores unchanged.

IN Support Note

- After
- The exact scored model HS-BM-3.28-10 is not named on SMA India's current product list. 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 list names Sunny Tripower 125, Sunny Tripower CORE2 and Sunny Highpower PEAK3. SMA India's home-energy pages discuss Sunny Boy Storage, a battery inverter, and a generic battery, not HS-BM-3.28-10. Home Storage product paths on sma-india.com return HTTP 404.
