I have a FLM02B with three current clamps on a three-phase system (no neutral wire), with the load very roughly split over 3 pairs of phases and a PV inverter on one pair. (schema attached)
The flukso is set to 3-phase (was 1 phase before)
I'm currently measuring very high power passing through the clamps, like 6000W whereas only 2600W is produced and less than 800W is consumed. The analog meter is running backwards.
When switching the inverter off, the flukso's measurements are within normal range (800W). After switching the inverter back on, the power appears to be realistic (having switched directions of course) for nearly a minute and then climbs back up to the impossible ranges. (logfile attached)
Is it even supposed to work in this condition? Am I doing something wrong?
(The clamps are tightened to a click. I couldn't avoid having the wires running from the clamps to the flukso close to the power wires for a few centimeter, but I minimized all other contact. The flukso is up to date (revision 250) and is fed with the original power supply and appears to be working fine otherwise. The number of clamp ports is set to three and the number of phases is set to the same. The inverter is a cheap chinese Sununo Plus 2.5K "transformerless")
