ARCA TERRA
The Arca Medina 20ft Deployable Habitat Unit is a fully self-contained, off-grid-capable living and working space built on an ISO 20ft standard dry van shipping container. Designed for rapid deployment in residential, industrial, and scientific environments, this proof-of-concept unit delivers a complete interior build-out with integrated 48V solar-hybrid electrical infrastructure. The interior features wood stud framing, closed-cell spray foam insulation, and radiant barrier OSB wall panels. A custom entry vestibule is created by pinning the original cargo doors open and framing an interior personnel door immediately behind them. A single 24"H × 30"W window is positioned on the long side wall for natural light and ventilation. The electrical system is centered on a 5kW solar hybrid inverter, a 48V battery bank (4× 100Ah LiFePO4), a DC fast charger, and a main distribution panel — all housed on the back wall. The exterior back wall provides a weatherproof main panel, a NEMA generator inlet, and solar roof input. All exterior electrical components are NEMA 3R or 4X rated.
