Hello,
I would like to ask, why my Multiplus II GX , AC Load show Power consuption 433W and actual true consuption is 485W (231x2.1=485W), difference of ~11%.
Is it a bug or feature? and if it is feature, is it possible to add option to change it to calculate consumption using current Volts and Ampere?
Thank you

I also have inaccuracy problems with my ESS 3 Phase system. In the first picture, it shows 119W of AC Loads...but there is nothing connected.
Loads are only connected to Critical Loads, AC Loads should be 0W
In the second picture, it shows 58W of Critical Loads, but there is nothing connected.

I think that the answer here is that the POWER FACTOR of your AC load is not unity - the voltage and current waveforms are not exactly in phase - usually due to an inductive load. Thus the true power is less than the Volts x Amps or the VA calculation. This is nothing to worry about for such a small difference. Your Power factor is (433/485) = 0.89 which is good. Some places have P.F. as low as 0.7, which can cause problems.
