Claim Text:
1. A system comprising: a controller configured to be coupled with an inverter that receives direct current and converts the direct current into an alternating current in order to supply the alternating current to plural loads during a common time period, the loads being connected to the inverter by plural respective contactors, the controller configured to control operations of the inverter and of the contactors in order to individually control which of the loads remain connected to and powered by the inverter and which of the loads are disconnected from the inverter; wherein the controller is configured to control an operating speed of the inverter and to direct the inverter to at least one of reduce the operating speed of the inverter to no greater than a first, non-zero, designated speed threshold or deactivate the inverter prior to disconnecting one or more of the loads from the inverter; and wherein the controller is configured to determine an operating speed of one or more of the loads after deactivating the inverter, and the controller is configured to open one or more of the contactors from a closed state responsive to the operating speed of the one or more of the loads decreasing to a speed that is no greater than a second designated speed threshold.
