Photovoltaic Inverter Information

What is Photovoltaic Inverter

A photovoltaic inverter is a key device in a photovoltaic power generation system that converts the direct current (DC) electricity generated by photovoltaic cells into alternating current (AC) electricity that can be used by the power grid or for local consumption. It acts as an interface between the photovoltaic modules and the electrical grid or the load, ensuring the efficient and stable operation of the photovoltaic power generation system.

History of Photovoltaic Inverter

In the early days of photovoltaic power generation, inverters were relatively simple and had limited functions. As the photovoltaic industry developed, the demand for more efficient and reliable inverters increased. In the 1980s and 1990s, with the continuous progress of power electronics technology, the performance and reliability of photovoltaic inverters began to improve significantly. In recent years, with the large-scale development of photovoltaic power generation, inverters have continuously evolved, with higher conversion efficiency, better grid connection performance, and more intelligent control functions.

Purpose of Photovoltaic Inverter

DC to AC conversion: The primary purpose is to convert the DC electricity generated by photovoltaic cells into AC electricity with the appropriate voltage, frequency, and phase to match the requirements of the power grid or the load, enabling the electricity generated by the photovoltaic system to be integrated into the power grid or used to power AC electrical equipment directly.

Power quality improvement: It can improve the power quality of the generated electricity, including reducing harmonic distortion, adjusting the voltage and frequency stability, and ensuring that the electricity meets the grid connection standards and the requirements of electrical equipment, thereby improving the reliability and safety of the power supply.

System control and monitoring: Many photovoltaic inverters have built-in control and monitoring functions, which can monitor the operating status of the photovoltaic system in real time, such as the power generation power, voltage, current, and temperature of the photovoltaic modules and the inverter itself. It can also control the operation of the system, such as adjusting the maximum power point tracking (MPPT) to optimize the power generation efficiency and protecting the system from overvoltage, overcurrent, and other faults.

Grid connection and protection: Ensure the safe and stable connection of the photovoltaic system to the power grid, and protect the grid and the photovoltaic system from potential faults and disturbances. For example, it can prevent reverse power flow, isolate the system in case of grid failure, and protect the inverter and other components from damage.

Principle of Photovoltaic Inverter

Photovoltaic inverters mainly use power electronics conversion technology. The DC electricity generated by the photovoltaic cells is first filtered and regulated to a stable DC voltage. Then, through the inverter circuit, which usually consists of power transistors or insulated gate bipolar transistors (IGBTs), the DC voltage is converted into AC voltage. The inverter circuit controls the switching of the transistors according to a certain modulation strategy to generate AC voltage with the desired frequency and waveform. At the same time, the inverter continuously monitors the grid voltage and frequency and adjusts the output AC voltage and frequency to match the grid parameters through feedback control, ensuring the grid connection and power quality.

Features of Photovoltaic Inverter

1. High conversion efficiency: With the continuous progress of technology, modern photovoltaic inverters have a relatively high conversion efficiency, usually above 90% and even higher in some advanced models. High conversion efficiency means that more DC power generated by the photovoltaic cells can be converted into AC power for use, reducing power losses and improving the overall energy efficiency of the photovoltaic system.
2. Wide input voltage range: It can adapt to a wide range of DC input voltages generated by photovoltaic cells under different light intensities and temperatures. This allows the inverter to operate stably even when the photovoltaic system is affected by factors such as weather and seasons, ensuring continuous power generation and conversion.
3. Good grid connection performance: It has excellent grid connection characteristics, including low harmonic distortion, fast response to grid voltage and frequency fluctuations, and the ability to meet the grid connection standards and requirements. It can ensure the stable operation of the power grid and the safe and reliable connection of the photovoltaic system to the grid.[!--empirenews.page--]
4. Intelligent control and monitoring: Equipped with intelligent control and monitoring functions, it can monitor the operating status of the photovoltaic system in real time and adjust the operation parameters automatically according to the actual situation. For example, it can implement MPPT control to maximize the power generation efficiency of the photovoltaic system and detect and handle faults in a timely manner, improving the reliability and maintainability of the system.
5. Multiple protection functions: It has various protection functions such as overvoltage protection, overcurrent protection, over-temperature protection, and anti-islanding protection. These protection functions can effectively protect the inverter and other components of the photovoltaic system from damage caused by abnormal conditions and ensure the safety of the system and the grid.
6. Compact size and light weight: Due to the continuous improvement of power electronics technology and the miniaturization of components, modern photovoltaic inverters have a relatively compact size and light weight, which is convenient for installation and transportation and can save installation space and costs.

Types of Photovoltaic Inverter

Central inverter: Usually used in large-scale photovoltaic power plants. It has a large power capacity and can convert the DC power generated by a large number of photovoltaic modules into AC power at one time. It has the advantages of high efficiency and low cost per unit power, but it requires a relatively complex installation and maintenance process and has relatively high requirements for the consistency of the photovoltaic modules.

String inverter: Each string of photovoltaic modules is connected to an independent inverter. It can adapt to different irradiances and temperatures of each string, improving the power generation efficiency and system reliability. It is suitable for medium and small-scale photovoltaic systems and rooftop photovoltaic power generation, and has the advantages of simple installation and easy maintenance.

Micro inverter: Installed on each photovoltaic module, it directly converts the DC power of the module into AC power. It has the best adaptability to the performance differences of each module and can maximize the power generation efficiency of each module. It is mainly used in small-scale photovoltaic systems and distributed photovoltaic power generation, but the cost is relatively high.

Precautions for using Photovoltaic Inverter

Installation environment: Install the inverter in a dry, ventilated, and cool environment, away from heat sources, humidity, and direct sunlight. The installation location should have sufficient space for heat dissipation and maintenance. Ensure that the inverter is installed on a flat and stable surface to prevent vibration and tilting.

Electrical connection: When connecting the inverter to the photovoltaic modules and the power grid, ensure that the connections are correct and firm. Use appropriate cables and connectors and follow the installation instructions and electrical safety regulations. Check the polarity and voltage of the connections carefully to prevent short-circuiting and electrical shock.

Grounding: The inverter must be properly grounded to ensure the safety of the system and the user. Connect the grounding terminal of the inverter to the reliable grounding system of the building or the photovoltaic system according to the regulations. Check the grounding resistance regularly to ensure that it meets the safety requirements.

System commissioning: Before the photovoltaic system is put into operation, conduct a comprehensive commissioning of the inverter and the entire system. Check the operation parameters of the inverter, such as the input and output voltages and currents, the grid connection status, and the protection functions. Ensure that the inverter and the system operate normally and meet the design requirements.

Regular maintenance: Regularly maintain and inspect the inverter to ensure the normal operation of the equipment. Clean the surface of the inverter regularly to remove dust and dirt and check the internal components and connections for signs of wear, corrosion, and overheating. Replace the filters and cooling fans if necessary. Check the software and firmware of the inverter regularly and update them in a timely manner to ensure the best performance and security.

Things to consider when purchasing Photovoltaic Inverter
