1. A stationary power supply device that supplies power to an external load, comprising:
a generator configured to generate electric power by power of an engine;
a housing container configured to house a battery;
a controller configured to determine a state of the power supply device, and
control charging of the battery housed in the housing container and power supply to the external load, by power from the generator,
wherein the generator includes a tank that stores fuel for the engine,
wherein the controller has a first mode of controlling power supply to the external load by power from the generator without using power from the battery, and a second mode of controlling power supply to the external load by both power from the generator and power from the battery such that power from the battery is used as an auxiliary power, and
wherein the controller is configured to, in a case of determining that a remaining amount of fuel in the tank is less than a threshold during controlling power supply to the external load by the first mode, automatically transition to the second mode and control power supply to the external load by the second mode.
