[Prior Art] Solar energy as a new energy' has an inexhaustible advantage over traditional fossil fuels. Today, with the increasingly severe international energy situation, various countries have increased their efforts to develop the solar energy industry. Solar energy applications are also becoming more widespread, such as satellite solar panels in the aerospace sector, solar water heaters in daily life. At present, there are mainly three types of solar energy utilization, including photoelectric conversion, photothermal conversion, and photochemical conversion. Among them, the most widely used one is photoelectric conversion, which converts solar energy into electrical energy. The solar cell is a typical photoelectric converter. 'In practical applications, the solar cell module is usually the core of the photovoltaic system. A complete photovoltaic system mainly includes the solar cell module, the junction box, and the electric conversion device. Inverters, as well as various instruments. The basic principle is that the solar module acquires solar energy and converts it into electrical energy. The junction box takes the output power out and converts the direct current generated by the voltage conversion into the required alternating current, and then directly connected to the utility grid. Or storing electrical energy to the battery 'receives the power of the solar cell module when controlled by the charge and discharge controller, and supplies power to the outside when discharging. Photovoltaic systems can be divided into two categories according to different application fields: independent light and grid-connected photovoltaic systems, independent photovoltaic system masters, and Μ φ Μ ^ . Wenyu application in communication systems, leather relay stations, TV differential turntables, "power shortage" A separate power supply for the region, such as the 201106495 small system, usually requires a battery.
