PROBLEM TO BE SOLVED: To reduce a failure due to earthquake or a risk such as a secondary disaster in a power conditioner.SOLUTION: A power conditioner 10 comprises: an inverter unit 14 that converts a DC power to an AC power toward a commercial power supply system 25; a control part 15 that controls an operation of the power conditioner 10; and a communication unit 17 that is constructed so as to receive earthquake information EI transmitted from an external part. The control part 15 determines whether or not the operation of the power conditioner 10 is forcibly stopped on the basis of the earthquake information EI received from the communication unit 17, and executes a shut-down operation when determining the execution of forced stopping.SELECTED DRAWING: Figure 1 【課題】パワーコンディショナーにおいて、地震に起因した故障や二次災害のリスクを低減する。【解決手段】パワーコンディショナー１０は、直流電力を商用電源系統２５に向けて交流電力に変換するインバータユニット１４と、パワーコンディショナー１０の動作を制御する制御部１５と、外部から送信される地震情報ＥＩを受信可能に構成された通信ユニット１７とを備える。制御部１５は、通信ユニット１７から受けた地震情報ＥＩに基づいて、パワーコンディショナー１０の運転を強制停止するか否かを判断し、強制停止すると判断したとき、運転停止動作を実行する。【選択図】図１
