Emerge Alliance DC Microgrid Standard

Emerge Alliance DC Microgrid Standard

A siginificant number of devices used in buildings require DC power, including phone chargers, computers, and other common electronic devices. These DC native devices require bulky power supplies to convert from AC to DC, which results in conversion losses as high as 50% for lower quality power supplies. As a greater number of buildings incorporate on-site renewable energy systems, which produce DC power, the concept of a DC microgrid increases in viability. The Emerge Alliance was developed to create a DC microgrid standard. The first round of certified products rely on a standard suspended ceiling grid to provide a busway for DC power. These products include LED lighting, occupancy sensors, and ceiling fans.
