Controls the switch 120 to perform a switching process in accordance with an instruction from the user (step S122). On the other hand, when there is no mode switching instruction or when the instruction information and the current mode information are the same (the mode is not changed), the process returns to step S119 to monitor the elapsed time in the standby state and the decrease in the SOC. Do.
  • the normal mode and the power saving mode can be selected, and when an abnormality is detected in the power saving mode, as in the normal mode, to the output side of the inverter. Since it is possible to select whether to automatically switch to standby mode, it is possible to arbitrarily set whether or not to supply power to the load during a power failure according to the connected load. It becomes possible to save electricity according to the situation.
