Abstract: A modular building structure can include a rigid chassis, vertical support components, and wall and roof component(s). The chassis can have storage compartments formed therein and can provide a foundation and floor for the structure. The vertical support components can couple to the chassis to provide a vertical framework for the structure. The wall and roof component(s) can couple to the vertical support components. The vertical support components and wall and roof component(s) can be disassembled from the chassis and stored within the storage compartments. The chassis can include a horizontal bottom panel, vertically oriented crossbeams above the bottom panel, and horizontal top panels above the crossbeams to form the storage compartments. The vertical support components can be poles and the wall and roof component(s) can be cloth. Leveling feet coupled to the bottom of the chassis can allow the chassis to be leveled with respect to the ground.

Abstract: A shelter, comprising: a foundation system configured to be filled in-place at a construction site with concrete; and a structure mounted to the foundation system, the structure walls and a roof comprising rigid foam insulation plastered with continuous filament winding (CFW), wherein the foundation, walls and roof comprise seamless transitions there between. A method of fabricating a shelter, comprising of a ‘rail system’ for pressing and gluing together foam walls, floor, ceiling, roof and foundation into a full structure. A foundation for a shelter, comprising: a portable tray configured to support the shelter, the portable tray comprising an interior configured to be filled or injected with a mass, and anchor elements configured to be anchored to an underlying formation. A modular tiling system that can be integrated into the foundation, comprising of movable functional components comprising a toilet, sink, speaker, lights, furniture, electronic equipment, cooking surface, lock box, trash bin and HVAC.

Abstract: Embodiments herein disclose an apparatus for a modular PV system. The apparatus may include a wire box coupled to an alternating current (AC) system through an AC bus and to both a first direct current (DC) power source and a second DC power source through a conduit; a first inverter having a first chassis attached to the wire box and being coupled to the first DC power source through the wire box, the first inverter comprising a first pass-through channel and a second pass-through channel; and a second inverter having a second chassis attached to the first chassis and being coupled to the second DC power source through the first pass-through channel and the wire box, wherein the first chassis and the second chassis are separate chassis.
