Where the ATHENA B fits

A floor-standing 51.2 V cabinet at 15,360 Wh or 17,152 Wh, with 200 A charge and discharge. It sits between the wall-mounted A series, which stops at 10,240 Wh, and the C series, which goes to 34,304 Wh — the size most whole-house retrofits actually land on.

Cells are rated ≥8,000 cycles at 0.5C with 95% depth of discharge and a design life of ≥10 years at 25 °C, and the cabinet is 48.5 × 26 × 77 cm on castors. The 200 A limit is the number to check against the inverter: a 12 kW unit at 51.2 V draws roughly 235 A at full load, so above that the C series with its 300 A peak is the correct choice.

15,360 / 17,152 Wh; 51.2 V; 200 A charge and discharge.
≥8,000 cycles, 95% DoD, ≥10-year design life.
Floor loading and door width — 77 cm tall, 26 cm deep.
