Grid-connected photovoltaic power generation and grid-connected photovoltaic inverter is one of the important parts of a power generation system, its main role is to DC into AC power supply can be used as a load converter, which is the inverse transform function of the rectifier devices. As the issue of grid-connected photovoltaic systems is that DC, if you want to share the load power, we need to equipped with inverter. Inverter through the semiconductor power switch turn-on and turn-off effect can be transformed into alternating current to direct current, is the inverse transformation process of rectification.
In view of grid-connected photovoltaic power inverter the importance of its quality will directly affect the safety of the local power grid, as well as the user's personal and property safety, for which the State "Golden Sun Demonstration Project" where the request and grid system uses the key to parts to go through domestic product certification. However, China's photovoltaic standard system is not perfect, there has been no published national grid inverter on national standards and industry standards, product certification, lack of technical basis, this is my country and grid-connected inverter product quality evaluation and enhancement of skills , and even China and the development of grid-connected photovoltaic power generation market had an adverse impact.
