Further, since the photovoltaic module 140 is arranged to supply power to the rf module 130, the capacity of the battery module 150 can be appropriately reduced, and the volume and weight of the battery module 150 can be reduced to further reduce the volume and weight of the whole power system, thereby facilitating the assembly and disassembly of the power system.
Further, to ensure that the photovoltaic module 140 can absorb more sunlight, the photovoltaic module 140 may be installed above the power system when installed. The photovoltaic module 140 is installed above the whole power system, so that the photoelectric conversion efficiency can be effectively improved, and meanwhile, sunlight can be prevented from directly irradiating the power system, thereby effectively reducing the temperature of the power system and prolonging the service life of components such as the battery module 150.
