Each of the first switch 217 and the second switch 219 may receive a control signal from the integrated control unit 221 and perform a switching operation based on the received control signal. Accordingly, each of the first switch 217 and the second switch 219 may perform an on/off operation to control the flow of current between the power generation system 500 and the grid 600 . Each of the first switch 217 and the second switch 219 may perform a switching operation based on the state of one or more of the power generation system 500 , the battery 230 , and the system 600 .

For example, when the amount of power required by the load 700 is greater than the amount of power delivered to the load 700 , the first and second switches 150 and 170 switch to an on state to operate the power generation system 500 and the grid 600 . Power may be delivered to the load 700 in each.
