  • Emergency load management using a DC microgrid during grid outage
    Patent number: 10020656
    Abstract: A DC building electrical system includes a DC power consuming device connected to a DC bus. A source of DC power is connected to the DC bus and powers the DC power consuming device. An energy storage device is connected to the DC bus and to a DC emergency load. The energy storage device powers the DC power consuming device in conjunction with the source of DC power, and powers the DC emergency load when source of power other than the energy storage device is available to the DC power consuming device.

  • DC power server for a DC microgrid
    Patent number: 9899867
    Abstract: A direct current power server configured to serve a direct current microgrid of a building. The direct current power server includes a direct current bus having branch circuits that extend from the direct current power server to provide direct current power to direct current loads of the building. The direct current power server directly integrates a local energy source and local energy storage into the direct current microgrid without attachment to the alternating current electrical grid.
