AIT SMART GRID CONVERTER: THE FIRST INDUSTRIALLY AVAILABLE FOUR-PHASE INVERTER

The AIT Smart Grid Converter is designed to integrate renewable energy sources and efficiently control energy flow in low-voltage networks, whether grid-connected or in island mode. The AIT Smart Grid Converter can be used to feed photovoltaic energy into a grid or energy community and to integrate battery systems as storage within such systems.

Its particular strength lies in supplying smaller networks that are operated temporarily or permanently in isolation (without connection to the public power grid). With its four actively regulated phases (L1, L2, L3, N), it can actively balance uneven loads. Its frequency control, based on the latest technologies, allows the AIT Smart Grid Converter to effectively take on the grid-forming function in island networks and seamlessly switch between grid-following and grid-forming operations.

Advantages of the AIT Smart Grid Converter (ASGC)

The AIT Smart Grid Converter is designed for modern smart grids and innovative microgrids with little or no mechanical inertia. It offers a seamless transition between grid-forming, grid-independent, and grid-supporting modes. Additional features, such as the highly reliable cooling concept designed for long service life, and the wide range of connectivity options like IEC61850, ModBus TCP, and SunSpec, distinguish the inverter system. Its modularity and parallelizability allow for performance increases in 36 kVA steps. The AIT Smart Grid Converter is perfectly suited to the requirements of modern smart grids.
