How big is the role of photovoltaic inverters?

Solar energy is a new energy that saves and protects the environment. Photovoltaic power station is a power generation system that uses solar energy and uses special materials. Therefore, photovoltaic power station has also become the most encouraged green power development energy project by the state. However, if a photovoltaic power station wants to operate normally, then a special material - photovoltaic inverter is indispensable. So what are the functions of photovoltaic inverter?

Maximum power tracking function to ensure maximum output power

The current and voltage of the solar panel change with the solar radiation intensity and the temperature of the solar panel itself, so the output power will also change. In order to maximize the output power, it is necessary to obtain the maximum output power of the panel as much as possible. The MPPT tracking function of the inverter can solve this problem.

current conversion

Due to the fickle weather, the direct current generated by solar modules is irregular and generally cannot be used directly. Just like a first-class chef, he will cut, fry, steam and cook the ingredients to finally turn them into delicious food. The inverter first tracks and analyzes the illumination of solar energy, and then goes through a series of procedures such as DC boost, inverter, and filtering, and finally converts it into pure sine wave AC that can be accepted by the grid. Just as chefs have high and low skills and the taste of the dishes they make is different, different inverter manufacturers also have big differences in quality, mainly in terms of solar energy utilization efficiency, safety and stability.

Troubleshooting

Photovoltaic power plants are generally installed in the wilderness or on the roof. The natural environment is harsh, and natural and man-made disasters will inevitably occur. Natural disasters such as typhoons, snow disasters, and sand and dust will damage the equipment. Small animals such as mice will bite the equipment. The thief cuts, the solar photovoltaic power generation system is related to the safety of the person, the power grid and the equipment. Improper design and selection and construction will also cause the system to short-circuit and so on. Therefore, a solar inverter is needed to check the safety of the system at all times. The inverter has the functions of voltage, current, frequency, and insulation inspection. When the diagnosis system fails, it will immediately alarm. If it is a safety accident that may endanger people and the power grid, stop power generation immediately, cut off the connection between the components and the power grid, and prevent the accident from further expanding.

Power Generation Statistics

The inverter records the real-time photovoltaic input voltage, current, power, output voltage, current, power, daily power generation of the photovoltaic system, and the monthly power generation can be viewed by users at any time. Through the data, you can understand the quality of the modules, the influence of the photovoltaic installation angle on the power generation, the comparison of the power generation in each month of the year, and also facilitate the communication between users and manufacturers.
