Grid-connected photovoltaic power inverter standard

Grid-connected photovoltaic power inverter standard


In fact, grid-connected photovoltaic power inverter standards is very important, but it has not attracted enough attention. China's PV 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's grid-connected photovoltaic power generation market, the development of adverse effects.

And grid-connected photovoltaic power generation and grid-connected photovoltaic inverter is a power generation system is one of the important parts, the 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.

Grid-connected photovoltaic power inverter will directly affect the quality of the local power grid security, and the user's personal and property safety. Therefore, the state in the "Golden Sun Demonstration Project" in the grid system uses the request and a key component to go through domestic product certification.
