It is mainly used to store the electric energy generated by photovoltaic modules (i.e., solar panels). This device enables the excess solar power to be used during non-sunshine hours or when the power generated instantaneously is insufficient, thereby improving the energy utilization efficiency and enhancing the stability of the system.

[0003] Chinese Utility Model Patent CN221428830U discloses a photovoltaic energy storage device. By starting the first motor, the first motor drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the first threaded rod to rotate, so that the first threaded rod drives the baffle to rotate, thereby realizing the adjustment of the direction of the photovoltaic panel; in practical applications, although the angle of the photovoltaic panel of this device can be freely adjusted to adapt to the position of the sun at different time periods, thereby improving the energy collection efficiency, the photovoltaic panel itself and its mechanical structure for controlling the steering are completely exposed outside and lack necessary protection measures. This makes the photovoltaic panel and the steering control structure vulnerable to the external environment, especially during non-working hours, which will directly affect the performance and long-term reliability of the system. Summary of the Utility Model

[0019] Refer to Figures 1 - 5 , the embodiment of the present utility model provides a portable photovoltaic energy storage device, which can be folded up as a whole during the non-working period of the device to protect the internal equipment.

[0020] Refer to Figure 1 and Figure 2 , in the embodiment of the present utility model, it includes a box body 1 and a storage battery 11 arranged in the box body 1. A wiring seat 13 is installed on the front side of the storage battery 11, and a through hole adapted to the size of the wiring seat 13 is opened at the corresponding position on the front side wall of the box body 1. External equipment can be directly connected to the wiring seat 13 through the through hole. Refer to Figure 1 , a foldable bracket 2 is installed at the middle position on the top of the storage battery 11. The movable end of the bracket 2 is rotatably provided with a cover plate 21, and the cover plate 21 is matched with the box body 1. When the bracket 2 is folded and retracted, the cover plate 21 will be buckled on the top of the box body 1 and form a closed protection space with the box body 1. Refer to Figure 1 , a photovoltaic main board 3 is installed on the front side wall of the cover plate 21, and a chute 211 is also opened in the upper part of the front side wall of the cover plate 21. Two photovoltaic sub-boards 31 are symmetrically slidably arranged in the chute 211 from left to right.
