The Microgrid Exchange Group defines a microgrid as "a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode."

Among their most valuable advanced functionalities is reactive power compensation (VAr support), which enables solar installations to actively participate in voltage regulation and grid stability maintenance. In this context, we'll use the SOLXPOW energy storage inverter as an example to demonstrate how to manage reactive power in a grid-tied solar system. Definition: The product of voltage and current (S = V × I), measured in volt-amperes (VA) or kilovolt-amperes (kVA). SVCs can provide rapid control f tempo-rary over voltages but they have limit-ed overload capability.
