Wind energy data logging

Tecnodave

I have been playing with energy logging and have recently purchased a NRG systems Symphonie Plus 15 channel data logger, NRG 40C anemometer, and NRG 200 wind vane.  It has 6 dedicated channels digital counters for anemometers, 2 analog channels for wind vane, four non dedicated analog channels ,and 3 non dedicated digital channels. I have only one SCM (signal conditioning module) for analog voltmeter, to use on the non dedicated channels.  Does anyone have expereince on these units. I bought it at auction for less than a consumer grade direct readout anemometer. It appears to be a very professional grade logger. Units are calibrated with documentation.
