[0002] Photovoltaic, that is, a photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiant energy into electrical energy. The energy of the photovoltaic power generation system comes from the inexhaustible and renewable solar energy. It is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology.

[0003] An independent photovoltaic power generation system consists of a solar photovoltaic array, a battery pack, a charge controller, a power electronic converter (inverter), a load, etc. Its working principle is that the solar radiant energy is first converted into electrical energy by the photovoltaic array, and then is converted by the power electronic converter to supply power to the load. At the same time, the excess electrical energy is stored in the energy storage device in the form of chemical energy after passing through the charge controller. In this way, when the sunlight is insufficient, the energy stored in the battery can be converted into AC 220V and 50 Hz electrical energy through the power electronic inverter, filtering and power frequency transformer boost for AC load use. The characteristic of solar power generation is that it generates electricity during the day, while the load often uses electricity all day long. Therefore, energy storage elements are essential in an independent photovoltaic power generation system. The energy storage elements used in engineering are mainly batteries.
