A vehicle system includes a power inverter coupled to an AC bus having a neutral conductor, a switching device coupled between the neutral conductor and a ground conductor, a sensor configured to measure an impedance between the neutral and ground conductors, and a control module. The power inverter is configured to provide AC power to an output via the AC bus. The control module is configured to transmit a signal to open the switching device to create a floating neutral configuration between the power inverter and the output, receive a signal from the sensor indicative of the impedance, and in response to the impedance between the neutral conductor and the ground conductor being less than or equal to a threshold, transmit a signal to the power inverter to provide AC power to the output. Other example vehicle systems and control methods are also disclosed.
