Abstract: A solar power generation system includes a string, an inverter a first shut-off device, and a second shut-off device. The string includes a plurality of solar cell module groups connected in series. The first shut-off device is connected to a first electric path connecting between the plurality of solar cell module groups. The second shut-off device is connected to a second electric path connecting between the plurality of solar cell module groups. The first shut-off device cuts off a connection between the plurality of solar cell module groups connected to the first electric path in response to a first control signal from the inverter. The second shut-off device is driven by an electrical power supplied from the first shut-off device and cuts off a connection between the solar cell module groups connected to the second electric path in response to a second control signal from the first shut-off device.

The second shut-off device is connected to the first shut-off device in a two-way communicable manner by a communication system different from power line communication and cuts off a connection between the solar cell module groups connected to a second electric path connecting between the plurality of solar cell module groups in response to a second control signal output from the first shut-off device by a communication system different from power line communication.

Abstract: A solar power generation system includes a string, an inverter a first shut-off device, and a second shut-off device. The string includes a plurality of solar cell module groups connected in series with each other. Each of the solar cell module groups includes one or a plurality of solar cell modules connected in series. The first shut-off device cuts off a connection between the plurality of solar cell module groups connected to a first electric path in response to a first control signal from the inverter. The second shut-off device is connected to the first shut-off device in a two-way communicable manner, is driven by an electrical power supplied from the first shut-off device, and cuts off a connection between the plurality of solar cell module groups connected to a second electric path in response to a second control signal from the first shut-off device.

Abstract: A communication device according to an embodiment includes an interpreter, a storage, and a generator. The interpreter is configured to interpret a content of a message addressed to a target user. The storage stores information on a personal feature of the target user. The generator is configured to generate a response message simulating a response by the target user on the basis of the content of the message addressed to the target user, which is interpreted by the interpreter, and the information on the personal feature of the target user stored in the storage.
