Disclosed is a household electricity storage system equipped with a service line (5), a distribution line (7), an electricity storage device (48), a voltage sensor (42) that detects the voltage of the service line (5), a current sensor (43) that detects the current charged to the electricity storage device (48) from the distribution line (7), a power adjustment unit (44) that adjusts the power charged to the electricity storage device (48) from the distribution line (7), and a control device (46) that controls the power adjustment unit (44). In cases in which the voltage of the service line (5) is lower than the threshold voltage, the control device (46) executes current control for controlling the power adjustment unit (44) in a manner such that the current charged to the electricity storage device (48) matches a reference value, and in cases in which the voltage of the service line (5) is higher than the threshold voltage, the control device executes voltage control for controlling the power adjustment unit (44) in a manner such that voltage of the service line (5) matches a reference value. |
