NEXICONTROL is the latest generation of VONSCH inverters for photovoltaic power plants and battery storage systems. These are high-efficiency Active Neutral-Point-Clamped (ANPC) three-level inverters that use Infineon® latest generation power semiconductors.
Texas Instruments® multi-core microprocessor with built-in FPGA and control algorithms ensure quick signal processing with a fast response for high control quality and outstanding local and remote diagnostics capabilities.
The abilities of NEXICONTROL inverters make them suitable for the most demanding applications in fields involving renewable energy sources, such as solar power plants and battery storage systems (in the GSE version).
