However, this causes the inconvenience that the cogeneration equipment as the power generation equipment that we own cannot be used in the event of an emergency. In view of this, the present inventors are also considering the independent operation of the cogeneration system by disconnecting the grid connection in the event of a power failure. However, as described above, the output specifications are determined so that small cogeneration devices for home use do not leave generated power on the assumption that they are connected to the grid, so in self-sustained operation, the load on the home will be reduced.

It is possible to return to grid-connected operation performed at a relatively low speed Z with low load.
