  The temperature sensor 64 measures the ambient temperature of the engine 10 or the generator 20 when performing a load test, and outputs the measured temperature to the control unit 61. When the ambient temperature is higher than a threshold (for example, a temperature (such as 40 ° C.) corresponding to a condition at the time of a load test defined by a law such as the Fire Service Law), the control unit 61 lowers the ambient temperature If the output (number of revolutions) of the first cooling fan 15 is increased and the ambient temperature still does not fall below the threshold, the control unit 61 stops the load test and causes the display unit 65 to display a warning.

The information is transmitted to an external device, and information on the on / off operation of the load test and the date and time setting for performing the load test are received from the external device.

  In the first embodiment, since the external air can be introduced from the intake opening (first intake opening 2a1) provided on the side surface of the container 2, the ambient temperature rise of the engine 10 or the generator 20 can be suppressed.

  In addition, since the engine 10, the generator 20, and the load test device 4 are housed in one case (container 2), the minimum necessary size (size and capacity) and optimum for the performance of the generator 20 can be obtained.

In particular, it is possible to combine the minimum required load test device 4 in order to perform the load test at a load rate of a predetermined ratio (for example, 25% to 70%) to the rated output of the generator 20.

  In addition, since the engine 10, the generator 20, and the load test device 4 are housed in one case (container 2), the engine 10 and the generator 20 are automatically controlled by using the control unit 61 to control them.
