Four NVL72 racks, six truck battery packs and warm-water cooling in one 20 ft box. The model turns on its own; drag to look around.

Overview
Compute puts four NVIDIA GB300 NVL72 racks — 288 Blackwell Ultra GPUs — into one 20 ft high-cube container, with six unmodified Windrose E700 battery packs on board. The packs carry the box for 1.4 hours at full load; with one Windrose Power container docked on the same DC bus, for 3.2 hours. The racks are cooled by warm water, so there is no chiller anywhere in the loop.
Inside the Container
Side by side and turned 90° so the fronts face one cold aisle. Each rack holds 18 compute trays (2 Grace CPUs + 4 Blackwell Ultra GPUs each) and 9 NVLink switch trays, 132–142 kW nominal and 155 kW peak.
Six E700 LFP packs, 1,051 kWh, behind an EI 60 fire-rated bulkhead. At full load each pack runs at 0.65C. The bay has its own 15 kW cooling, off-gas detection, aerosol suppression and roof deflagration vents.
A 2 × 500 kW bidirectional PCS turns the 595–869 V pack bus into 415 V three-phase. A 1,250 A overhead busway feeds each rack’s power shelves.
Two 700 kW coolant distribution units (N+1) feed the racks at 45 °C and take them back at 57 °C. A roof dry cooler with four EC fans rejects the heat. Two 30 kW room-air units handle what the cold plates do not catch.
