Architecture describes the product boundary. It is not a system design or an equipment-pairing decision.

Usable capacity

90% of this battery’s nominal capacity is usable, 12.78 kWh in the scored configuration.

12.78 kWh usableScored configuration: SB14200. Published range 6.48–12.78 kWh.

The remaining 10% 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.

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 is anchored to SB14200. Smart Hybrid and later Redback hybrid systems are separate product identities. Scored model: SB14200 · checked 2026-08-01. Evidence.

Sources & references · checked 2026-08-07

Strong evidence coverage

26 of 26 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.

    Redback publishes no round-trip efficiency figure for this system. Recorded as a reviewed absence rather than a null placeholder, so the rubric's missing-mode applies cleanly.
