Inverter, also known as inverter power supply, is a converter device that converts DC electric energy into AC electric energy. Photovoltaic inverters are inverters used in solar photovoltaic power generation systems and they are an important component of photovoltaic systems.The efficiency of the inverter affects the efficiency of the photovoltaic power generation system, so it is very important to select the right inverters.
With the continuous development of technology, photovoltaic inverters will also develop to achieve smaller size, higher efficiency, and better performance indicators.
Working principle: The core of the inverter device is the inverter switching circuit, referred to as the inverter circuit for short.The circuit completes the function of inverter by turning on and off the power electronic switch
Features:
1.High efficiency is required.
Due to the high price of solar cells, in order to maximize the use of solar cells and improve system efficiency, we must try to improve the efficiency of the inverter.
2.High reliability is required.
At present, photovoltaic power station systems are mainly used in remote areas, and many power stations are unattended and unmaintained. Those inverter are required to have reasonable circuit structure, strict component selection, and various protection functions such as: input DC polarity reverse protection, AC output short circuit protection, overheating, overload etc
3.The input voltage is required to have a wide range of adaptation.
Because the terminal voltage of the solar cell changes with the load and the intensity of sunlight. Especially when the battery is aging, its terminal voltage varies widely. For example, the terminal voltage of a 12V battery may vary from 10V to 16V. This requires the inverter to ensure normal operation within a larger DC input voltage range.
