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

Usable capacity

95% of this battery’s nominal capacity is usable, 15.5 kWh in the scored configuration.

15.5 kWh usableScored configuration: enblock E15.5.

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.

Strong evidence coverage

17 of 17 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.
