Solar power generation is a new field of energy conservation and environmental protection. It is a hot project in the world and has become a photovoltaic power generation. At present, distributed photovoltaic power generation has become a pension investment project for many families, but many people do not have some accessories for photovoltaic power generation. I understand very well, such as photovoltaic inverters, many engineering companies involved in this industry do not know why to use solar pv inverter in solar photovoltaic power generation?
Why use solar pv inverter in solar photovoltaic power generation?
The principle of solar photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. The key component of this technology is the solar cell. The solar cells are packaged and protected in series to form a large-area solar cell module, and then combined with a power controller and the like to form a photovoltaic power generation device. The whole process is called photovoltaic power generation system. The photovoltaic power generation system is composed of solar battery array, battery pack, charge and discharge controller, solar pv inverter, AC power distribution cabinet, solar tracking control system and other equipment.
The role of solar pv inverter in it
A solar pv inverter is a device that converts direct current into alternating current. Since the solar cell and the battery are DC power supplies, and the load is an AC load, the solar pv inverter is indispensable. According to the operation mode, the photovoltaic inverter can be divided into independent photovoltaic inverters and photovoltaic grid-connected inverters. Independently operated photovoltaic inverters are used in stand-alone solar cell power generation systems to power independent loads. Grid-connected inverters are used in solar cell power generation systems that operate in parallel. Solar cells generate direct current under sunlight, but systems powered by direct current have significant limitations. For example, fluorescent lamps, televisions, refrigerators, electric fans, etc. cannot be directly powered by DC power, as are most electric machines. In addition, when the power supply system needs to raise or lower the voltage, the AC system only needs to add a transformer, and the technology of raising and lowering the voltage in the DC system is much more complicated. Therefore, in addition to special users such as communication and meteorology that directly use DC power, photovoltaic inverters are required to be installed in photovoltaic power generation systems that produce electricity for production and use.
solar pv inverter is the core of the whole photovoltaic power generation system. It can not only enable the normal operation of photovoltaic power generation, but also monitor the working state of this photovoltaic power station in real time, which brings convenience to the later maintenance work.
The load is classified into resistive load, inductive load and capacitive load.Resistive load: the load with no phase difference between current and voltage is resistive load, such as rice cooker, light bulb, electric stove, electric soldering iron, etc.I
