When measuring a consumption of 2.2 kW at my heat pump ("WP buiten") with my Shelly EM, it also measures a reactive power of almost -600 W. (Which I think is abnormally high?)
At the same time, the other current clamp on my Shelly EM measures the total consumption of my house: 2.6 kW and -1.000W of reactive power.
I have no clue where this extra -400W of reactive power comes from.
No special appliances were running at this time. I have a PV-array with 4 kW inverter, but it was not delivering any power yet at 7h06...
