In the process of building and operating photovoltaic power plants, solar inverters in electrical equipment play a very important role. Like photovoltaic power generation system technology, they continuously improve operating efficiency and conversion power, and are combined with photovoltaic modules and other power generation equipment. Most efficient photovoltaic system.

Inverters, also known as power regulators and power regulators, are an essential part of photovoltaic systems. The main function of the photovoltaic inverter is to convert the direct current generated by the solar panel into the alternating current used by household appliances. All the electricity generated by the solar panel must be processed by the inverter before it can be exported to the outside world. Through the full-bridge circuit, the SPWM processor is generally used for modulation, filtering, boosting, etc., to obtain sinusoidal AC power that matches the lighting load frequency and rated voltage for use by the end users of the system. With an inverter, DC batteries are used to provide AC power to appliances.

Usually, the process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called a rectifier circuit, and the device that realizes the rectification process is called a rectifier or a rectifier. Correspondingly, the process of converting DC power into AC power is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that realizes the inverter process is called inverter equipment or inverter. Inverters, also known as power regulators, can be divided into two types: independent power supply and grid-connected use according to the use of inverters in photovoltaic power generation systems. According to the waveform modulation method, it can be divided into square wave inverter, ladder wave inverter, sine wave inverter and combined three-phase inverter. For inverters used in grid-connected systems, they can be divided into transformer-type inverters and non-transformer-type inverters according to the presence or absence of transformers. There are many types of inverters, so special attention should be paid when selecting the model and capacity. Especially in solar power generation systems, the efficiency of photovoltaic inverters is an important factor in determining the capacity of solar cells and storage batteries.

Due to the diversity of buildings, it will inevitably lead to the diversity of solar panel installations. In order to maximize the conversion efficiency of solar energy and take into account the beautiful appearance of the building, this requires the diversification of our inverters to achieve the best solar energy. convert.
