How about a super portable solar container power supply

By combining solar panels and storage in solid, mobile shelters, solar-powered shipping containers are providing solar electricity from cities to rural villages around the world, reshaping the generation, transmission, and use of electricity. When the grid is hundreds of feet away (or non-existent), a self-contained power solution is ideal. Integrating necessary power equipment such as transformers, switchgear, energy storage units and control. RPS supplies the shipping container, solar, inverter, GEL or LiFePo battery bank, panel mounting, fully framed windows, insulation, door, exterior + interior paint, flooring, overhead lighting, mini-split + more customizations! RPS can customize the Barebones and Move-In Ready options to any design. Solar power containers combine solar photovoltaic (PV) systems, battery storage, inverters, and auxiliary components into a self-contained shipping container. Thanks to foldable solar arrays, the container is rapidly deployable — operating within hours to support power needs across diverse scenarios.
