4Wire setup strange readings

Open krikke999 opened this issue 5 years ago • 0 comments

I have flashed the latest Firmware on the Emontx and adjusted the parameters:

  • define EMONESP and //#define RFM69CW
  • double vCal = 260.00; // for the EU adapter use 260.00
  • I am using the CT 100A clamps so iXCal and iXLead left to default

installation overview:

main -> IEM -> EmonTX -> consumers and on Phase 3 I have my PV installation injecting into the grid most of the time

When I compare the values from a Schneider IEM3155 with the values from the emontx connected after the IEM. I see the following values: image

Are these diviations normal for CT readings? Does this firmware identifies direction => PV injection are not? Why is CT4 connected to N is so high?
