Solar Powered Micro Grid Systems

Solar Powered Micro Grid Systems

Sun-In-One™ has engineered a “containerized” off-grid energy system that eliminates expensive on-site installation and wiring of the major components associated with converting solar energy into usable electricity. The customized containers with the inverters, disconnects, and switch gear come pre-wired and pre-tested. These containers come ready to install and put into use, and require only a few auxiliary wires to connect them to the system, essentially making it a “plug and play” system.

Our expertise spans over 1 Gigawatt of energy production throughout the US and the world. This includes one of the largest 100% Solar Micro Grids in the world, located on Annobon Island, EG. This system includes 5 Megawatts of solar power and 10 Megawatts of storage.

What is a Micro Grid?

Micro grids are autonomous grids that operate either in parallel to, or “islanded” from, existing utility power grids. Micro grids use distributed renewable energy that act like small power plants near the buildings, villages, or islands they supply – not hundreds of miles away like large, centralized power plants. This means that these grids experience less “line loss”, or loss of electrical power over distance. Micro grids also remove the need to construct vast amounts of infrastructure just to deliver power. Instead, a micro grid ranging from 1.0 kW to 50 MW in size can be deployed or installed almost anywhere.

Why install a Sun-In-One™ Micro Grid?

Sun-In-One’s Micro Grids are an economic alternative wherever a reliable stand-alone power grid is necessary due to geography, infrastructure, or security of supply. Our system’s modular design makes it perfect for situations with sensitive timetables while eliminating expensive on-site installation costs. This design also makes the grids completely scalable, allowing additional components to be integrated into the system at any time, step by step, according to the energy demand.
