Illogical calculation.!? #3

Screenshot_20230325-145224 what bothers me is that the total current is 4.7A and the total real power is only 362w. is that formula for calculating power a bit messy, I think that with 4A current the real power should be at least 1000w. the code has not been modified, it is original as you wrote it.

Real power takes into consideration the power factor. This is what is impacting your calculation.

Try inverting the direction of the CT clamps.
