Up for Sale is a custom-built Grid Tie Inverter System or Active Front End originally built for use with Wind Turbines. This device safely ties a 750VDC bus to the utility grid (480V 3-Phase). It includes an Eaton/Vacon AFE Inverter, Filtering Components, and a Basler Protective Relay used to safely connect to the grid. We built and tested this for a Wind Turbine customer who went out of business before installing it. We'd prefer to sell it intact to the right customer before we dismantle it for the individual parts. The Cabinet Includes these Major Components: DC Input Filtering Eaton AFE Drive (SPA072A1-4A3N1) Output Sine Filter Output EMI Filter Basler BE1-700 Digital Protective Relay Fuses Cabinet Cabinet Filtered Vents and Fan This unit operates essentially the same way the Eaton AFE drive does in its intended industrial environment. When connected to the power grid, it produces a 750VDC bus. Any device attached to this bus that draws power will be supplied by the AFE. Any device that puts power into the bus (raises the voltage), will cause the AFE to export power onto the grid. In a factory, this is used to allow several motor drives to share a common DC bus and share any regenerative/braking power they produce - either among each other or onto the grid. It also provides Power Factor Correction. In our application, it allowed several wind turbines to share a DC bus and only require one 'expensive' grid-tie system for several turbines. To build this unit, we surrounded the AFE drive with the filters and safety devices necessary to use this function in a non-industrial environment. More information is available upon request. Let us know if you have any questions. We may eventually part this out if not sold intact, so let us know if you have any interest in individual components. Thanks for Looking
