PV Grid Connection

In recent years, solar energy generation has become popular since it is clean, inexpensive and has low installation costs, especially where grid power is inconvenient or unreasonable expensive to connect. However, due to the intermittent and unstable characteristics of renewable energy, its grid connection may have an influence on the stability of grid operation.

Based on the deep knowledge of electrical grids, NR introduces the integrated renewable grid-connection solution to address efficient ac/dc conversion, high power quality and smooth grid interconnection.
