NEXICONTROL GSE / PV 100-200 kVA

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).

Features

• built-in AC fuses
• built-in measurement of leakage currents
• DC interference filter
• AC interference filter
• built-in AC surge protector, DC surge protector optional
• precharging from both DC and AC sides
• possibility of DC side isolation to operate as reactive power source

Communication

• MODBUS RTU, based on RS485 for backward compatibility with older generation of VONSCH inverters
• MODBUS TCP, for control and diagnostics over Ethernet LAN, or its wireless version IWLAN (option)
• Built-in graphic display for quick insight into the actual status of the inverter
• Possibility to connect UNIPANEL graphical control panel
• Setup, diagnostics, and control over the VONSCH DRIVE STUDIO application, version 4.3 and later
