ARTICLE 712. DIRECT CURRENT MICROGRIDS712.1. Scope.‚ÄÉThis article, new as of the 2017 NEC, and in reference to the definition, covers dc power distribution systems that are powered by at least two interconnected dc power sources and that actively supply dc loads (which can include dc-to-ac inverters that supply ac loads). These systems do not generally have a connection to an ac primary power supply such as a utility service entrance. However, some are equipped with dc-ac bidirectional converters or dc-ac inverters. These systems offer inherent energy efficiency, because many renewable energy sources are inherently, or easily configured as, dc sources, including wind turbines, fuel cells, and photovoltaic systems…
