NEXICONTROL Three-phase Inverters
Models
Characteristics and advantages
Advanced ANPC technology
NEXICONTROL’s three-level inverters are based on high-efficiency Active Neutral-Point-Clamped (ANPC) technology, which uses the latest generation of Infineon® semiconductor devices for maximum efficiency and reliability.
Powerful control and diagnostics
The system features control algorithms that run on an embedded FPGA and a multi-core microprocessor from Texas Instruments. These technologies provide fast signal processing with short response times, resulting in high quality control. They also enable efficient local and remote diagnostics.
Ideal for demanding applications
NEXICONTROL is designed for use in the most demanding applications such as photovoltaic power plants and Li-ion or LiFePo Battery Storage (GSE version), supporting a wide range of renewable energy sources.
Integrated safety and security features
The inverters include integrated features such as built-in AC fusing, leakage current measurement, DC and AC suppression filters, and optional surge protection for both AC and DC to enhance system safety and reliability.
Advanced communication and compatibility
The inverters support communication via MODBUS RTU to RS485, which guarantees compatibility with older generations of devices. Modern connectivity is provided via MODBUS TCP for LAN or IWLAN (optional). A built-in graphic display is available for easy monitoring of the inverter status, while the system also supports an external UNIPANEL graphic control panel.
Modern management software
Setup, diagnostics and control are provided by the VONSCH DRIVE STUDIO application version 4.3 and later, which offers advanced management and monitoring options.
