Therefore, solar power generation is increasingly favored by the public. A solar power generation device is a device that converts solar energy into electrical energy. A solar energy energy storage device is usually electrically connected to the solar power generation device and is used to store the electrical energy generated by the solar power generation device and then supply power to users according to the electricity demand.

[0003] In the existing solar energy energy storage device during use, a connecting wire is used to connect the solar panel and the battery pack to store the electrical energy emitted by the solar panel. However, since different specifications of solar power stations require different specifications of connecting wires, and the specification of the reserved wire passing hole of the energy storage device is fixed, there is a gap between the connecting wire and the wire passing hole, and it is not easy to seal it.

Therefore, there is an urgent need for a new type of solar energy energy storage device to solve the above problems. Summary of the Utility Model
