Solar inverter centralized inverter

Concentrated photovoltaic  sine wave power inverters  and is commonly used in large power stations (> 10 kw) system, a lot of parallel photovoltaic group of string is connected to a single centralized inverter dc input, the use of the general power three-phase IGBT power modules, the use of smaller power field effect transistor, at the same time using DSP conversion controller to improve the quality of the output power, making it very close to the sine wave current. Biggest characteristic is the system of high power, low cost. But the pv group string matching and part of the covering film, lead to the efficiency and capacity of the whole solar system. At the same time, the whole pv system reliability of generating a photovoltaic cell set of adverse effects of work status. The latest research direction is using space vector modulation control, as well as the development of new  grid inverters  topology connection, to get part of the load cases of high efficiency.
In SolarMax (sory & middot; mike) focused on the inverter, you can attach a photovoltaic array interface box, to monitor each string of strings of photovoltaic panels, such as one group work is not normal, the system will put this information on to the remote controller, at the same time can through the remote control will stop working, and the line which will not be reduced because of a string of photovoltaic (pv) list of fault and affect the entire solar system work and energy output.
