Centralized Inverter Of Solar Inverter

Centralized inverter is generally used in large photovoltaic power stations (>10kW) in the system, many parallel photovoltaic series are connected to the same centralized inverter DC input, the general power of the use of three-phase IGBT power module, the use of smaller power field effect transistor, while the use of DSP conversion controller to improve the quality of the generated power. Making it very close to the sine wave current. The biggest feature is the high power and low cost of the system. However, due to the matching and partial shading of photovoltaic series, the efficiency and electrical capacity of the entire photovoltaic system are caused. At the same time, the power generation reliability of the whole photovoltaic system is affected by the poor working condition of a certain photovoltaic unit group. The latest research direction is the use of space vector modulation control and the development of new inverter topological connections to obtain high efficiency under partial load conditions. In the SolarMax(Sori Mike) centralized inverter, you can attach a photovoltaic array interface box to monitor each string of photovoltaic panels, if one of the strings is not working properly, the system will transmit this information to the remote controller, and the string can be stopped by remote control. Therefore, it will not reduce and affect the work and energy output of the entire photovoltaic system because of the failure of a series of photovoltaic strings.
