Below are the reasons for the large-scale use of solar panel string inverters from Yinghe Energy's solar panel components, Zhejiang distributed photovoltaic power station and Zhejiang photovoltaic module manufacturers:

Reason 1: The string inverter adopts a modular design. Each photovoltaic string corresponds to an inverter. The DC end has a high-power tracking function. The communication end is connected in parallel and connected to the grid. Its advantage is that it is not affected by the module difference between the strings. The impact of shadow occlusion, while reducing the mismatch between the optimal operating point of the photovoltaic cell module and the inverter, greatly increasing the power generation.

Reason two: string inverters also have the advantages of low self-consumption, small impact of faults, and convenient replacement and protection. The centralized inverter itself consumes a lot of power and the ventilation and heat dissipation of the machine room. The system protection is relatively complicated. When a fault occurs, the entire power station will be paralyzed. When a string inverter fails, as long as a string of components will stop power generation, the entire power station It can operate as usual, and then the loss is greatly reduced. In addition, the string-connected grid-connected inverter is small in size, light in weight, and very convenient for transfer and installation. It does not require professional tools and equipment, nor a special power distribution room. It can simplify construction in various applications. , Reduce land occupation, DC line connection does not require DC combiner box and DC distribution cabinet, etc. This means that the correction time period of the string inverter is shorter than the correction period of the centralized inverter.
