A microgrid is a small, independent power system that produces and distributes electricity locally, while also interconnecting with a main electric grid when desired. Hybrid microgrids combine the benefits of multiple power sources, such as solar photovoltaics and diesel generators to achieve high reliability at an affordable cost. Energy storage is an increasingly important component for many microgrid applications as the cost and reliability of batteries and other storage technologies has improved over time.

Microgrids are designed to meet the unique power requirements and resource availability at each project site. Intelligent controllers automatically balance the use of a generator and energy storage to maximize the use of solar energy and minimize the overall cost of electricity.
