NEXICONTROL 400 100-200
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 combination of cutting-edge SiC and IGBT 7 power modules.
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).
The NEXICONTROL 400 100 inverter has successfully passed tests at the ČEZ Distribuce testing laboratory in Hradec Králové. The resulting certificate of conformity according to PPDS – Annex 4 (non-synchronous generating modules of categories A1, A2 and B1) for connection to the distribution network in the Czech Republic covers the entire NEXICONTROL power range up to 200 kVA (inclusive).
