For solar inverters, the input is generally low-voltage DC output high voltage frequency AC output voltage waveform has two types: sine wave and modified sine wave. Pure sine wave power inverter corresponding thereto may be suitable for all types of load, have a good ability to adapt, due to its harmonic content is small, high power quality, so it has good market prospects.
Energy conversion technology development so far, it is no longer an optional back-up device, but the power supply system is an indispensable part. In particular, and combine photovoltaic power generation system that enables independent development of photovoltaic power supply have a broader space. In China's vast central and western areas without electricity, the population density, live in scattered, and has abundant solar energy resources, is very suitable for the development of stand-alone photovoltaic technology. Combining photovoltaic technology and power conversion technologies will be greater development, become an important way to solve the power shortage in the western region without electricity or electricity.
