1. A method comprising:
receiving a bus voltage of a direct current (DC) bus connected to an energy source;
determining whether the received bus voltage is less than a bus voltage threshold;
in response to determining the received bus voltage being less than the bus voltage threshold, determining an occurrence of an arc event in an apparatus that includes the DC bus and the energy source;
determining a connection status of the energy source to the DC bus; and
in response to determining the received bus voltage is less than the bus voltage threshold, and in response to the connection status indicating the energy source is connected to the DC bus, disconnecting the energy source from the DC bus.
