Abstract
A storage battery system includes: a grid-connected storage battery; and a first current sensor that is provided in an electrical circuit linking the storage battery and the grid and detects a current in the electrical circuit the storage battery system having the electrical circuit connected with one or more power generators. The storage battery system includes: a second current sensor that is provided in the electrical circuit such that the one or more power generators are connected between the first current sensor and the second current sensor; and a controller that calculates generated power of the one or more power generators based on outputs obtained from the first current sensor and the second current sensor.
