GSE COMP 400 is a transformerless inverter designed for direct connection of an inverter or arbitrary number of parallel ranged inverters on the primary side of the grid transformer with ratio 0,4/XX kV.

GSE COMP inverters do not allow off-grid operation.

GSE COMP 400 serves as a battery-fed bidirectional inverter for 400V three-phase power system. VONSCH GSE COMP 400 is the ideal product to provide the following:

• Peak-shaving
  with a proper control, GSE COMP can be used to reduce maximum power peaks
• Reactive power compensation
  thanks to the measurement of currents and load voltages, the total reactive power of the system can be continuously and quickly controlled
• Frequency control
  Frequency control is only relevant in small island networks called "microgrid", where surplus or lack of power is reflected in an increase or decrease of the grid frequency (droop control)
• Charging / discharging and forming the battery
  Thanks to the fast control of the DC current (battery current), the inverters can be used to charge and recharge batteries with very high efficiency

Features:

• High efficiency
• Fast start-up
• Fast reaction time to step change of load
• Long durability of device
• Ecological device – minimal consumption in standby
