Where the high-voltage rack fits

A rack-mounted system built from 5 kWh, 10 kWh or 16.07 kWh modules in series, giving 204.8–819.2 V system voltage and 20.48–257.2 kWh per stack. High voltage is the point: at these voltages the current stays low, so cable sizes and losses drop compared with a 51.2 V bank of the same capacity.

It carries UN38.3, CE and IEC62619, with ≥6,000 cycles on the 100/200 Ah modules and ≥8,000 on the 314 Ah module, BMS protection across all five fault classes, and CAN2.0 / RS485 communication. This is plant-room equipment for commercial and off-grid sites; for a single household the ATHENA C cabinet is the right scale.

204.8–819.2 V; 20.48–257.2 kWh per stack; 16S per module.
UN38.3 / CE / IEC62619; altitude ≤2,000 m.
Cabinet heights up to 2,100 mm — confirm the plant-room door and ceiling.
