[0032] Below, based on Figure 1~Figure 3 A first embodiment in which the present invention is embodied in a residential power distribution system will be described. First, the outline of this system will be described.
[0033]
[0034] like figure 1 As shown, a house is provided with a power supply system 1 for supplying electric power to various devices (lighting equipment, air conditioners, home appliances, audio-visual equipment, etc.) installed in the house. The power supply system 1 operates various devices using a commercial power supply (AC power supply) 2 for household use as power, and also supplies power from a solar cell 3 generated by sunlight as a power source to various devices. The power supply system 1 supplies electric power to AC equipment 6 operated by inputting an AC power supply (AC power supply) in addition to supplying power to DC equipment 5 operated by inputting a DC power supply (DC power supply).

[0083] Next, a second embodiment of the present invention will be described. The power supply system in this example basically has the same figure 1 and figure 2 structure shown. Therefore, the same reference numerals are attached to the same component configurations as those in the above-mentioned first embodiment, and detailed description thereof will be omitted.
[0084] Then, in the power supply system 1 of this example, the roles of the first storage battery 51 and the second storage battery 52 are switched at predetermined timings. That is, if image 3 As shown in the graphs of (a) and (b), when the first storage battery 51 is set as the initial state for power failure and the second storage battery 52 is set for non-power failure, the first storage battery 51 The storage battery 51 maintains a predetermined level of charge (for example, a fully charged state). In addition, the second storage battery 52 for non-power failure is charged with the electric power gene...

[0096] Next, a third embodiment of the present invention will be described. The power supply system in this example basically has the same figure 1 and figure 2 structure shown.
[0097] Such as Figure 4 As shown in (a) and (b), the second storage battery 52 is housed under the floor of the house. This underfloor is constituted as follows. That is, if Figure 4 As shown in (b), an opening 72 is formed on a floor 71 in a house, and a stepped portion 73 is formed at an inner peripheral edge of the opening 72 . Then, the storage box 74 is inserted into the opening 72 from above the opening 72 . The storage box 74 is formed with an upper opening, and a flange 75 in the form of a shoulder (panel) is formed on the peripheral edge of the opening. The flange 75 is engaged with the stepped portion 73 of the opening 72 , thereby restricting the downward displacement of the storage box 74 . That is, the positioning of the storage box 74 in the up-down direction is realized. I...
