Therefore, most are fixed or distributed modular PV power generation boxes and small-power mobile energy storage cabinets. Designing a mobile, off-grid integrated power generation box with energy storage exceeding 100kW, ensuring both rapid and safe installation, stable power generation, and convenient mobility, is a pressing issue that needs to be addressed.

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] like Figure 1 and Figure 9 As shown, this invention provides a mobile photovoltaic power generation and energy storage integrated box, which includes a hollow box body 1. The interior of the box body 1 is divided into a photovoltaic panel storage cavity 3 and an energy storage placement cavity 4 by a partition plate 2. A grid-connected inverter 5 and several photovoltaic panels 6 are installed in the photovoltaic panel storage cavity 3. The photovoltaic panels 6 are electrically connected to the grid-connected inverter 5 via cables (not shown). The photovoltaic panels of this invention can be Trina Solar 500W monocrystalline photovoltaic panels. Several photovoltaic panels 6 are arranged side-by-side in the photovoltaic panel storage cavity 3 via a sliding guide device 7 and are transported using the box body 1. When the photovoltaic panels 6 are needed to generate electricity, they are simply removed from the box body 1 and laid out. An energy storage cabinet 8 and an STS cabinet 9 are installed in the energy storage placement cavity 4. A cable trench (not shown) is provided at the bottom of the partition plate 2 to facilitate cable passage. The grid-connected inverter 5 is electrically connected to the STS cabinet 9 via a cable passing through the cable trench, and the STS cabinet 9 is electrically connected to the energy storage cabinet 8 via a cable. The grid-connected inverter 5, energy storage cabinet 8, and STS cabinet 9 used in this invention are all common structural devices in the industry, and are designed to be achievable by those skilled in the art. The door panel of the enclosure 1 is equipped with a cooling fan 12, a lighting lamp (not shown), and a suction louver 13. The suction louver is a common louver structure with an integrated filter cotton.

[0026] Furthermore, each photovoltaic panel 6 is mounted on a photovoltaic panel support 10, which is a rectangular frame structure adapted to the photovoltaic panel 6. The photovoltaic panel 6 is fixedly connected to the photovoltaic panel support 10 by bolts. Adjacent photovoltaic panel supports 10 are hinged together to facilitate the interconnection of multiple photovoltaic panels 6 and also to facilitate the folding and unfolding of multiple photovoltaic panels 6. Preferably, the photovoltaic panel support 10 of the present invention has 3 or 4 rows, and the photovoltaic panel support 10 is welded from rectangular tubes. The photovoltaic panel 6 is connected to the grid-connected inverter 5 using a 6 square millimeter DC cable, forming two bus bundles, one with 3 rows of connecting lines and the other with 4 rows of connecting lines, and the connectors are plug-in type. The grid-connected inverter 5 is connected to the STS cabinet 9 using a 70 square millimeter cable, and the cable passes through the reserved cable terminal. The STS cabinet 9 is connected to the energy storage cabinet 8 using a 50 square millimeter cable.

[0027] Furthermore, the sliding guide device 7 includes a pulley 71 for sliding the photovoltaic panel 6 into the photovoltaic panel storage cavity 3. The pulley 71 is located at the bottom of the photovoltaic panel 6, and a guide groove 75 is sleeved on the outside of the pulley 71 for guiding. The opening of the guide groove 75 extends outward, and the pulley 71 and the guide groove 5 are connected to the bottom of the photovoltaic panel support 10. A guide rail 72 is provided below the pulley 71 to guide the movement of the pulley 71. The guide rail 72 is located at the bottom of the housing 1. In use, the photovoltaic panel 6 can be moved on the guide rail 72 using the pulley 71. Several interconnected photovoltaic panels 6 can be folded and moved into the photovoltaic panel storage cavity 3 for storage and transportation, or the photovoltaic panels 6 folded in the photovoltaic panel storage cavity 3 can be moved out of the photovoltaic panel storage cavity 3 and then laid out for power generation.

[0028] Furthermore, a photovoltaic panel support fixing device 11 for positioning the photovoltaic panel support 10 is provided on the upper part of the housing 1. The photovoltaic panel support fixing device 11 includes fixing rods 111 horizontally arranged on both sides of several photovoltaic panels 6. The fixing rods 111 and the photovoltaic panel support 10 are provided with corresponding pin holes 112. The fixing rods 111 and the photovoltaic panel support 10 are connected by fixing pins (not shown). Connecting rods 113 are provided at both ends of the fixing rods 111. The fixing rods 111 and the connecting rods 113 are connected by bolts. The connecting rods 113 are connected to the top of the housing 1. When the photovoltaic panel 6 is stored in the photovoltaic panel storage cavity 3, the two fixing rods 111 can be respectively set on both sides of the photovoltaic panel 6, so that the pin holes 112 on the fixing rods 111 correspond to the pin holes 112 on the photovoltaic panel support 10, and fixing pins are inserted to achieve the effect of positioning the photovoltaic panel 6. To remove the photovoltaic panel 6 from the photovoltaic panel storage cavity 3, simply remove the fixing pin and remove the fixing rod 111 from the connecting rod 113.

[0029] The present invention also includes a guide rail support 73 for unfolding the guide rail 72. The guide rail support 73 has an inverted V-shaped cross-section. The ends of two adjacent guide rails are sleeved on the guide rail support 73, and the guide rail support 73 provides support. Both the guide rail support 73 and the guide rail 72 are provided with insertion holes 74. The two insertion holes of the guide rail support 73 correspond to the insertion holes 74 at the ends of the two guide rails 72 provided on the guide rail support 73. A U-shaped insert 76 is provided on the insertion hole 74. Both ends of the U-shaped insert 76 pass through the insertion holes 74 on the guide rail 72 and the guide rail support 73 to position the guide rail 72 and the guide rail support 73. When unfolding the photovoltaic panel bracket 10, the guide rail 72 must be laid first. The length of the guide rail 72 is based on the length required for the photovoltaic panel bracket to be fully unfolded. In use, the photovoltaic panel 6 is taken out from the photovoltaic panel storage cavity 3 and laid on the guide rail to support the photovoltaic panel 6.

[0030] This invention adopts an integrated design, which can effectively improve the power generation capacity, up to 200KW. When using it, you only need to find a good site and open the photovoltaic panel to generate electricity. It can be used in grid-connected or off-grid mode. Moreover, it has its own energy storage system, which can provide power for a long time when there is no sunlight. It also features quick and convenient photovoltaic panel deployment and retraction, and easy mobility and transportation.
