In addition, since the second connecting frame 142 is usually installed on the wall by using a bolt fixing method, the back of the second connecting frame 142 is provided with a plurality of installation holes 1423 for installing wall hanging bolts, the supporting plate 1421 is provided with first notches 1424 matched with the installation holes, and the first notches 1424 are arranged opposite to the corresponding installation holes 1423; thus, when the second connecting frame 142 is installed, the bolt can pass through the first notch 1424 and the installation hole 1423 to be connected to the wall, and the bolt avoids the supporting plate 1421 through the first notch 1424, so as to avoid the interference influence of the supporting plate 1421 on the installation of the bolt. Meanwhile, the first connecting frame 141 is provided with a second notch 1413 matched with the first notch 1424, since the end of the bolt is exposed outside the second connecting frame 142 after the bolt is fixedly installed on the wall, after the first connecting frame 141 is installed on the second connecting frame 142, the exposed end of the bolt is located in the second notch 1413, and the hanging plate 1411 can avoid the end of the bolt through the second notch 1413, so that the installation convenience is improved.
In addition, for the power storage module 3, since the plurality of storage batteries 31 are used, the overall weight of the power storage module 3 is heavy, the power storage module 3 can be directly connected to the first connecting frame 141, the first connecting frame 141 serves as a suspension member and also serves as a load-carrying member, the weight of the power storage module 3 is borne by the first connecting frame 141, the thinner and lighter housing 1 can be used, and only the structural strength of the first connecting frame 141 needs to be enhanced, so that the use amount of materials can be saved, which is beneficial to reducing the manufacturing cost.
