Grid reporting: Ampers inconsistent vs Watts

Simply looking at grid in VRM 1.3A should be 305W and not 27W as reported for L1.

These numbers are always inconsistent no matter when you read them. It is the same even if I set external grid meter my ET340, or internal the 3 quattros 10kva.

Also in cerbogx if I look at external grid meter device, it reads the same inconsistencies A vs W just like internal inverters.

Why is that? Does the formula P=U*I does not apply when calculating these numbers for some reason? The W seem to be the correct value, but why is A weird?

P = U * I * PF where PF is the power factor.
