Abstract: The present invention provides for a low cost, light weight, high strength earthquake certified power and equipment enclosure module which provides for an effective housing of DC batteries allowing for simultaneous dual voltage functionality with intelligent evacuation of thermal and toxic residuals. Stacking and interlocking the modules provides an environment for housing diverse electrical components making the invention enclosure invulnerable to obsolescence. Intuitive disassembly and reassembly allows the cabinet modules to be moved easily too hard-to-reach locations eliminating the need for costly cranes, lifts or excessive man-power. The design delivers the smallest footprint with the highest power density, embedded alarming and thermal management ensures safety in operation.
