Solar energy (synchronization sine wave) inverter is the development direction of solar energy and wind power generate, which delegated the most attractive resource utilization technology in the twenty first century. Because it could input the electric power into electric network, avoid collated accumulator, cut out the process of accumulator’s stored energy and discharge, which could fully use the electric power generated by renewable resource, reduce energy wasting and reduce system cost. Synchronization electric power generation system could use commercial power and renewable resource as the local power of AC load that reduce the load power shortage rate. At the same time, the renewable resource synchronization system could make the peak shaving action for public utility grid.
