Abstract
An arrangement that provides power to an electrical device includes an inverter, first and second switches, and a bypass controller. The first switch has open and closed positions, and is operable to connect the inverter to the electrical device when in the closed position. The second switch has open and closed positions, and is operable to connect a utility power line source to the electrical device when in the closed position. The bypass controller is operable to cause a transition sequence in which the first switch changes to the open position and the second switch changes to the closed position. The bypass controller is further operable to: cause continuous actuation of a first indicator when the first switch is closed; cause continuous actuation of a second indicator when the second switch is closed; and cause intermittent actuation of the second indicator during at least part of the transition sequence.
