Summary:To provide a heat pump hot water supply system that performs at least one of delaying restarting for a predetermined time or restarting with output restriction, when sunshine is not stabilized.SOLUTION: A heat pump hot water supply system (1) equipped with a heat pump unit (2), a hot water storage tank unit (3), a photovoltaic power generation device (4), and control means, is configured to heat hot water by using power supplied from the photovoltaic generation device (4) and power supplied from a commercial power supply. The control means performs at least one of delaying the restarting of the heat pump unit (2) for a predetermined time, or restarting with output restriction, when detecting the starting and stopping of the heat pump unit (2) within a set time, during the operation of the heat pump unit (2) during power failure.SELECTED DRAWING: Figure 1 【課題】日照が安定しない場合には再起動を所定時間遅延させるか、出力制限を伴う再起動にするかの少なくとも1つを行うようにしたヒートポンプ給湯システムを提供する。【解決手段】ヒートポンプユニット(2)と貯湯タンクユニット(3)と太陽光発電装置(4)と制御手段)とを備えたヒートポンプ給湯システム(1)は、太陽光発電装置(4)から供給される電力及び商用電源から供給される電力を用いて湯水を加熱可能に構成され、制御手段は、停電時におけるヒートポンプユニット(2)の運転時において、設定時間内にヒートポンプユニット(2)の起動、停止を所定回数以上検知したときには、ヒートポンプユニット(2)の再起動を所定時間遅延させるか、出力制限を伴う再起動にするかの少なくとも1つを行う。【選択図】図1
