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.
