PROBLEM TO BE SOLVED: To provide a system interconnection system for fuel cell in which a converter is prevented from stopping, when electricity is not outputted sufficiently from a fuel cell.SOLUTION: A system interconnection system 1 for fuel cell includes a converter 20, a system interconnection inverter 30, a converter input voltage detection unit 40, and a control unit 50. The converter input voltage detection unit 40 detects a DC voltage outputted from a fuel cell 10 and inputted to the converter 20. When the DC voltage detected by the converter input voltage detection unit 40 goes below a predetermined level near the lowest input allowable voltage, the control unit 50 controls the system interconnection inverter 30 to reduce an AC current outputted therefrom. |
