Actually, U*I=Q (apparent power, in kVA)
Active power (in kW) P = U * I * cos phi
Low cos phi can be caused by electric motors and transformers (inductive loads) or, less frequent, capacitive loads.
But even then, your system would have a cos phi of 0.5, which is really really bad.
Are you sure the config of your meter is correct?
this is used to integrate a non victron inverter. i looked into the parameters but i am not sure what to configure. In Victron Connect I can not really adjust a lot.
I did double check but I could not really find a problem in the wiring. e.g The phase of the current clamp matches the phase of the Voltage Sensing wiring. I will double check again.
