If air-conditioner controller 200 detects that the power output of photovoltaic cell group 66 is greater than and arranges load power demand, then control photovoltaic cell group 66 unnecessary power distribution is charged to built-in electrical storage device 42 or external electrical storage device 44, and control preferentially to charge to built-in electrical storage device 42.
If air-conditioner controller 200 detects that the output current of built-in electrical storage device 42 is lower than allowing set point, then control photovoltaic cell group 66 and built-in electrical storage device 42 is charged; If detect, the power output of photovoltaic cell group 66 is less than set point, then control startup external power supply and photovoltaic cell group 66 are charged to built-in electrical storage device 42 jointly, and namely preferentially power to control photovoltaic cell group 66 higher than the output voltage of external power supply by the output voltage of photovoltaic cell group 66 being set to relatively high pressure output.
In the present embodiment, preferably, the power supply voltage of aircondition 20 is DC48V.The power supply voltage of the output of built-in electrical storage device 42, external electrical storage device 44 is also set to DC48V.
