Abstract
A dual-source facility power system includes a first electrical interface configured to receive DC power from at least one photovoltaic panel; a second electrical interface configured to receive AC power from an electric utility grid; a third electrical interface configured to deliver AC power to one or more branch circuits or appliances; and a controller. The controller is configured to monitor characteristics of AC power received from the electric utility grid. When one or more such characteristics fail to meet one or more predetermined specifications, the controller is further configured to disconnect the second electrical interface; deliver, to one or more branch circuits or appliances, AC power derived from DC power received from the at least one photovoltaic panel; and individually monitor AC current delivered to one or more of the branch circuits or appliances.
