CHARGE/DISCHARGE SYSTEM

This charge/discharge system includes a storage portion (71) storing power generated by a power generation module (21) coupled to a power grid (50) and discharging power to a load and a control portion (75) including a function of stopping discharge of the storage portion on the basis of a result of comparison between a first threshold set in response to the amount of power that can be generated by the power generation module and the amount of power consumption corresponding to power consumed by the load.
