Description

Technical Field

[0001] The utility model relates to the technical field of solar power generation, and particularly relates to a portable solar power generation device. Background Art

[0002] Photovoltaic power generation is a power generation method that converts solar energy into electrical energy. It mainly consists of solar panels, a controller, an inverter, and a storage battery. The solar panels use their photovoltaic effect to convert light energy into electrical energy and store it in the storage battery, and then convert it into alternating current through the inverter for use by the load, or the alternating current can be transmitted to the public power grid.

[0003] After retrieval, Chinese Patent Publication No. CN217115955U discloses an outdoor portable solar power generation system, which includes a first box body and a second box body connected to each other by a hinge. The outer vertical walls of the first box body and the second box body are both slidably connected with a first solar panel in the horizontal direction, and a plurality of second solar panels are arranged between the two first solar panels, and the plurality of second solar panels are connected to each other by a connecting belt. A storage battery electrically connected to the solar panels is arranged inside the second box body. In this solution, by slidably connecting the first solar panels to the outside of the two box bodies, arranging the second solar panels between the first solar panels, and connecting the second solar panels by a connecting belt, it adapts to the angle change between the two box bodies, so that it has a larger energy absorption area. By combining the solar panels with a suitcase having a current conversion function, the convenience of the device is improved.

However, when this patent is used, the solar panels are restricted by the size of the box body, and its power generation capacity is limited. Moreover, when the box body is upright, the included angle between it and the sun is affected, and its power generation efficiency will decrease. If the box body is tilted, it will increase the contact between the storage battery and the inverter and external objects, which is not conducive to the heat dissipation of the two.
