Imitation sine wave the grid inverter defects and

not only do not understand so many AC inverter exactly what the different functions, or What are the disadvantages and advantages in different areas of use is that most of our technical staff also do not understand so many types of inverter , Why escalating until now to the requirements of the "pure sine wave" era, why can not meet the grid requirements by some people accused of the technology does not meet the technical specifications of the large-scale grid? Directly, most photovoltaic grid most of the supporting manufacturers inverter sine wave-shaped "glitch" too many problems, too much the cause of "glitches" and very profound practical significance in reality, even if the grid-connected inverter inverter efficiency reached 97%,Grid tie inverter, but the real contribution to the power grid and electrical equipment rate may reach 80%, this is what causes it? ,power inverter.
