What are the differences between the Centralized inverters、String Inverter and Micro inverter?

Centralized inverter: DC current from multiple solar panels is combined and fed into a centralized inverter which converts it into AC power before feeding it into the grid. STRING INVERTER: DC current from a string of solar panels is first converted into ac power by a string inverter before being fed into the grid. Micro inverter: DC current from each individual solar panel is converted into ac power by a microinverter before being fed into the grid.
