Decision evidence

What the documents establish

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

Usable capacity

95% of this battery’s nominal capacity is usable, 13.68 kWh in the scored configuration.

13.68 kWh usableScored configuration: SH-G3-BE with three Pylontech US5000 and SH6000-G3. Published range 9.12–18.24 kWh.

The remaining 5% stays in the pack as reserve; the home never draws it.

Nominal capacity is not stated here. The usable kWh and the depth-of-discharge percentage are sourced separately, at times from different documents and different module counts, so dividing one by the other would produce a nominal figure no manufacturer published.

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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. Scored on the three-module reference configuration; the published range describes two to four modules. Redback's website markets up to 51.2 kWh, which its own data sheet does not support and which is not credited. Scored model: SH-G3-BE with three Pylontech US5000 and SH6000-G3 · checked 2026-08-03.

Strong evidence coverage

28 of 28 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.
