  • Histogram with normal distribution overlay in Excel

    This tutorial will walk you through plotting a histogram with Excel and then overlaying normal distribution bell-curve and showing average and standard-deviation lines. To produce my random normal samples I used VBA function RandNormalDist by Mike Alexander. I created samples with a mean of 100 and standard deviation of 25, function RandNormalDist(100, 0.25). The actual mean and standard deviation…

  • Log solar generated to PVOutput with LabVIEW

    Here is the full LabVIEW code to read a CMS2000 inverter solar generation, including power, voltage and temperature, and then logging it to PVOutput. The data is read from the CMS2000 every 1 second and averaged over 5 minutes, as PVOutput only supports 5 minute intervals. The averaged value gives a better representation of the parameter…

  • Connect to CMS2000 solar inverter with LabVIEW and read power

    After a few weeks of ‘chasing the sun’, finally got something I am happy with, LabVIEW connects to the CMS2000 via serial interface and reads the parameters. Programmed as a state-machine, basic error checking and fail safes. Note, I am using a RS232 to TCP/IP adapter, I am guessing a lot of the peculiarities are due…
