The common structure of on grid solar power generation system includes centralized, series, multi-series and AC modules. In centralized, series and multi-series systems, there are series and parallel solar cell modules, so the maximum power point tracking of the system is aimed at the whole series-parallel solar cell array, which can not take into account each solar cell array in the system. The utilization of single solar cell array is low, the system has poor ability to resist local shadows, and the system expansion flexibility is not enough. The solar on grid micro-inverters are connected with a single solar cell module, which can directly convert the DC output of the solar cell module into AC and transmit it to the grid. They have the following advantages:
1.It ensures that each solar cell module runs at the maximum power point, and has a strong ability to resist local shadows.
2.By integrating micro-inverters with solar cell modules, can realize modular design, plug-and-play and hot plug-and-play, while the system expansion is simple and convenient.
3.Micro-inverters do not occupy installation space independently. Distributed installation is easy to configure. They can make full use of space and adapt to different installation directions and angles.
4.The system has high redundancy and reliability, and the failure of a single module will not affect the whole system.
