PROBLEM TO BE SOLVED: To provide an inverter controller which starts an inverter most properly taking the staying state of a system interconnection inverter into account. SOLUTION: If it is decided by an overvoltage deciding unit 35 that an inverter is outputting an overvoltage immediately before the inverter is stopped, an upper limit voltage from the optimum operation voltage range is read out from a memory 32 by an inverter control unit 34. On the other hand, if the stoppage of the inverter is not caused by the output of the overvoltage, a voltage value at the time of a maximum output before the inverter is stopped is read out from the memory 32 by the inverter control unit 34. The control is performed by using the upper limit voltage value and the voltage value at the time of the maximum output as voltage instruction values to re-start the inverter. |
