PROBLEM TO BE SOLVED: To reduce the workload in the operation confirmation test.SOLUTION: An inverter 1 for system interconnection includes a system protection function unit 7 performing system protection operation for protecting a system power supply, a generation system protection selection unit 5 for receiving the selection of any one of system protection types indicating the type of abnormality of a system power supply during the operation confirmation test, and a system protection arbitrary operation unit 6 receiving a protection instruction for making the system protection function unit perform the system protection operation during the operation confirmation test. When the protection instruction is received by the system protection arbitrary operation unit, the system protection function unit performs the system protection operation, on the basis of the selection received by the generation system protection selection unit.SELECTED DRAWING: Figure 1 |
