Solar Energy
Photovoltaic inverters convert Solar Energy into alternating current, off-grid systems ensure independence from the grid, and compensation units optimize consumption and reduce energy losses.
NEXICONTROL is an advanced three-level inverter designed for photovoltaic power plants and Battery Storage applications that uses high-efficiency ANPC (Active Neutral-Point-Clamped) technology and the latest Infineon® semiconductor elements.
With control algorithms in an embedded FPGA and a multi-core microprocessor from Texas Instruments, it offers fast signal processing, high control quality, and local and remote diagnostics capabilities. It is ideal for demanding renewable energy applications including Li-ion and LiFePo battery systems.
PV COMP is a photovoltaic inverter that converts the DC voltage from the PV panels into a three-phase AC voltage with nonstop reactive power compensation, even during night or cloudy weather.
Designed for hybrid “microgrid” systems and cooperation with large aggregates, the PV COMP 350 allows direct connection to the primary side of a 0.35/11-33 kV ratio grid transformer.
With a wide input voltage range from 580 V to 850 V and a maximum output of 150 kVA, it offers flexibility, modularity and efficiency, while being adaptable to the specific requirements of photovoltaic power plants.

Real applications of Solar Energy
Covering own consumption (Zero supply to the grid)
Due to the requirements of various electricity distribution companies for zero grid supply, we have extended these options to large three-phase photovoltaic solutions from VONSCH. The high adaptability and robustness of our solutions allows them to be used even in the very stringent conditions of some distribution companies.

Off-grid Solutions
In addition to classic “grid” PV solutions, we also offer off-grid solutions, without the need for any distribution network or generator. Our solutions rely on the quality and reliability of FOTO CONTROL and GSE CONTROL three-phase inverters and, of course , on the quality of LG Chem® Li-ion or Hoppecke® lead-acid batteries and the complete discharge and charge management directed by VONSCH. The range is from a capacity of just a few kWh and 2 kW peak power to a capacity of several MWh at peak power of more than 1 MW.

Active power factor compensation
Active compensation of the reactive energy (not only) of the PV plant is possible with the UNIKOMPENZATOR compensation unit. This allows to compensate the resulting power factor of the power plant in the range from -0.95 capacitive to -0.95 inductive. When using an external power factor measurement, compensation is also possible on the HV side.
