摘要：PURPOSE: To provide a system interconnection system made to be capable of smoothly starting an inverter circuit. CONSTITUTION: A system interconnection system, is provided with a protective relay control circuit 8 starting at a voltage or more where supply voltage from a control power supply circuit 9 is lower than reference voltage, but not performing abnormality detecting action in a commercial power system 3 until output voltage of a solar battery 1, based on a detection value by a solar battery voltage detecting means 10, is judged to be the second prescribed value or more higher than the first prescribed value, before starting an inverter circuit 2 with a start.
