PROBLEM TO BE SOLVED: To display and record a plurality of error detection information pieces resulting from the same cause as a single detection information. SOLUTION: A linked system inverter comprises a controller I including a DC/AC converter, a DC voltage detector, a DC current detector, an AC voltage detector, a part of the entire part of AC current detector, a computer and a real-time clock. The controller I comprises a non-volatile memory means S as a means to record the information, a display means D as a means to display the data for users, a plurality of error detecting means E1, E2, E3 as the means for detecting an error as the error detecting information for a plurality of monitoring items of the error factor, and a centralizing means C for centralizing a plurality of error detecting information pieces detected from a plurality of error detecting means resulting from the same cause as the single error information and then generating the centralized error information E11 as one detected information piece. |
