[0006] The photovoltaic power generation and energy storage conversion device provided by this utility model includes a base and a charging controller. A box is installed on the base. Several horizontal seats and vertical seats are fixedly spaced inside the box. The several horizontal seats and vertical seats divide the inside of the box into several storage cavities.

[0007] The storage cavity is equipped with a battery pack and a support plate. The support plate is placed on the cross seat, and the battery pack is placed on the support plate. Two forklift slots are symmetrically opened on the cross seat.

[0012] In a preferred embodiment, a mounting slot is provided on one side of the storage cavity, and a cooling fan is installed inside the mounting slot.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using this device, if it is necessary to replace or repair the battery pack, the operator can first disconnect the connecting wires between the corresponding battery packs, then drive the hydraulic forklift to one side of the box, extend the two forklift arms into the two forklift slots respectively, and then lift the support plate by using the forklift arms for transfer. The installation is the same, and the operation is simple and convenient.

[0015] 2. The battery pack can be fixed by setting a limiting plate and two opposing seats to prevent it from slipping during the transfer process.
