Intelligent wind turbine control
GFI - Grid Feed Inverter
Complete system integration
Benefits
The GFI - Grid Feed Inverter is an optimized cabinet
assembly providing you a complete control system for
your small wind turbine. The GFI contains everything
needed from turbine power conversion, control and
monitoring, external equipment interfacing and power
feed in to the grid according to legislations in Europe.
• Complete control system
• Precisely programmable power curve
based on rotor speed (up to 100 set-points)
• Easy plug & play installation
• Optimized design for easy OEM
cabinet integration
• Interface for generator thermal protection
• Complete system integration
• Low cut-in wind speed
• High energy capture
• All-in-one product
• Excellent return on investment (ROI)
The GFI Grid Feed Inverter is designed for the OEM’s
offering a fast and cost effective integration. This advanced grid feed inverter comes in 6 power sizes from
10kW to 30kW in single and 3-phase versions.
Optionals
• 4.3” TFT touch display
• Programmable logic controller for
enhanced system control
• Remote user display
• Extended warranty
Monitoring + setup/commissioning
The GFI Grid Feed inverter is specifically designed
for small wind turbines but can additionally be used in
all induction and permanent magnet generator based
system such as Hydro Power, Wave Energy, Biomass
and CHP systems.
The optional multifunctional touch screen panel enables the OEM and end-user to fully observe and monitor the GFI inverter. This can be done either on-site
or together with the standard web monitoring solution
from DVE Technologies.
