PROBLEM TO BE SOLVED: To provide a power generation system having plural power conditioners in which the state of the overall system can be grasped while suppressing the cost-up.SOLUTION: One of plural power conditioners is set as a master unit, the other power conditioners are set as slave units, and operation information of all the power conditioners 1 is integrated at the master unit. An external LED display device 16 is connected to the master unit, and a light emission pattern of the external LED display device 16 connected to the master unit is changed according to the content of the plural integrated operation information. For example, when even one power conditioner is under an error state, the external LED display device is flickered. When all the power conditioners are under no error state, but even one power conditioner operates, the external LED display device is turned on, and in the other cases, the external LED display device is turned off.
