The long term data files are stored by default at 10 minute intervals; there is no real time clock in the
VCS II so the on time is stored in the first column, with the cumulative energy in kWh stored in the
second column. Snapshot data are also stored regarding battery voltage, current, and temperature. To
help with turbine and wiring diagnosis all 3 phase voltages, as well as the turbine frequency are stored.
The dataxxxx.csv files are the only place that cumulative kWh and run time are stored, so if the files are
deleted or modified an incorrect kWh or run time will be displayed.
All calibration data are stored in cal_data.txt, these values are determined for each unit during initial
testing. They should not need to be altered after initial calibration.
