(57) Abstract :
To supply electrical power generated by a photovoltaic array, i which is installed in a balcony or the like by a resident himself
/herself of an individual unit, efficiently and at low cost to a plurality of electrical loads of the individual unit in a
distributedmanner while ensuring no excess or shortage of electrical power supply and performing electrical power transfer, a
photovoltaic array (11) for generating direct current (DC) power by receiving sunlight is installed in a balcony (1) of the
individual unit, the DC power is converted by an inverter (13) into alternating-current (AC) power, and the AC power output from
the inverter (13) is supplied to the plurality of electrical loads in a distributed manner by a distribution board (38) of the individual
unit. On the other hand, a magnitude of DC power generated by the photovoltaic array or a lithiumion battery and a magnitude of
electrical power consumed by the electrical loads are compared by an electrical power comparator. Depending on the comparison
result, an electrical power switch may supply the DC power via the inverter to the electrical loads or a low-voltage system, or may
supply electrical power from the low-voltage system to the electrical loads or the lithiumion battery.
