Centralized inverter
Centralized inverter is generally used in the system of large-scale photovoltaic power station (>10kW), many parallel photovoltaic strings are connected to the DC input of the same centralized inverter, generally the use of three-phase IGBT power modules for large power, the use of field-effect transistors for small power, and the use of DSP conversion controller to improve the quality of the generated power, so that it is very close to the sine wave current. The biggest feature is the high power and low cost of the system. However, due to the influence of the matching of photovoltaic strings and partial shading, the efficiency and electrical capacity of the entire photovoltaic system are caused. At the same time, the power generation reliability of the entire photovoltaic system is affected by the poor working condition of a certain photovoltaic unit. The latest research direction is the modulation control using space vectors, and the development of new inverter topological connections to achieve high efficiency in part-load cases. On the SolarMax centralized inverter, an interface box of the photovoltaic array can be attached to monitor the photovoltaic sail panel strings of each string, if one of the strings is not working properly, the system will transmit this information to the remote controller, and at the same time, the string can be stopped by remote control, so as not to reduce and affect the work and energy output of the entire photovoltaic system due to the failure of a string of photovoltaic strings.
String inverter
String inverter has become the most popular inverter in the international market now. The string inverter is based on a modular concept, where each PV string (1kW-5kW) passes through an inverter with maximum power peak tracking at the DC end and is connected to the grid in parallel at the AC end. Many large-scale PV power plants use string inverters. The advantage is that it is not affected by module differences and shading between strings, and at the same time reduces the optimal operating point of the PV module.
A mismatch with the inverter, which increases the amount of electricity generated. These technical advantages not only reduce the cost of the system, but also increase the reliability of the system. At the same time, the concept of "master-slave" is introduced between strings, so that when the system cannot make a single inverter work in a single string, several groups of PV strings are linked together, so that one or several of them can work, so as to produce more power. The latest concept is to form a "team" of several inverters to replace the "master-slave" concept, which takes the reliability of the system one step further.
