Project Overview
This project is situated in a region of Sudan experiencing unstable or unreliable grid electricity supply. To address the challenge of securing stable power for critical local infrastructure—such as factories, mining sites, or telecommunications base stations—a highly integrated 40-foot foldable photovoltaic energy storage container system has been deployed. Operating under a “self-generation for self-consumption, surplus power not fed into the grid” model, the system employs an integrated photovoltaic-storage unit to enable intelligent grid-connected/off-grid switching. During grid outages, it automatically transitions to off-grid operation, utilising solar energy and storage batteries to sustain power supply to loads, thereby ensuring continuity and reliability of production and operational activities.

Application
Sudan possesses exceptional solar resources, with the project site characterised by extensive annual sunshine hours and high solar radiation intensity, making it an area exceptionally rich in solar energy and highly suitable for photovoltaic power generation systems. This project aims to establish an intelligent, autonomous “PV + energy storage” microgrid system to meet the round-the-clock power requirements of specific sites, effectively addressing challenges posed by frequent power outages or grid failures.
