There is the grid Voltage and Current, then there is the pure sine wave inverter Voltage and Current. What I’d like to do is measure these parameters for both, then perform the math to find out just how beneficial this off grid system is, while I slowly expand it. I may be able to do it already, but one area of doubt is the line in EmonLib for Voltage and Current:
emon1.voltage(2, 234.26, 1.7); // Voltage: input pin, calibration, phase_shift
I am not sure what to put in for calibration and phase_shift.
Could the calibration be the UK line voltage? If it is then mine would be 118.50. Is that correct? As for the phase_shift, I know what phase shift is, but as for it’s context here, I’m at a loss, Stephen
