How do I disable the auto-reverse function for CTs? - I only want to measure current moving in one direction and get zero when it is moving in the reverse direction.
I have 3 phase incoming and 3 phase solar.
I would like to be able to calculate:
I have two CT’s on each incoming phase and one CT on each solar phase. If my arithmetic/algorithm is right then.
- Export = what is measured in the outbound direction on the main incoming cables on each phase (just add up the phases to get the total)
- Import = What is measured in the inbound direction on each phase (we often are exporting on two phases and importing on one as the washing machine, well pump etc. operate)
- Consumption = generated + import - export
For the import CT I have ‘allow negative power value’ unchecked and ‘reverse’ unchecked. When we are exporting on that phase IoTaWatt shows the ‘reverse current arrow ring’ icon and gives a positive reading. I would like/expect the import CT to say zero when we are exporting.
Is there a config setting somewhere that forces reverse current to record zero?
