Thanks, will you send us a screenshot? We did add + and - to watts in this version, I imagine that you had reverse current this whole time, it is just that you did not notice it. In the previous version we have watts on each line (all positive values) then in a separate area we had direction of current on each line.

Total Watts is still the same as it was before. But now we have added Total Net Watts as a new calculated value.

If you are seeing reverse kWh increment or negative watts and you should not, then you probably have something that is not properly connected.

If you are NOT sending electricity back out through the meters (towards the grid) then you should NOT be seeing any incrementing kWh on display #02 (Reverse kWh) of the meter itself. Here are some things to check (this assumes a “single phase, “120/240” system):

Make sure the arrows on the CTs are facing towards the load.

Make sure you have CT1 on line 1, CT2 on line 2, etc.

Make sure the voltage reference from Line 1 goes to Line1 power on the meter, make sure the voltage reference from Line 2 goes to Line2 power on the meter, etc. Connect your neutral to the meter.

Make sure your CT wires are connecting into the meter in the right order: For OmniMeters it should be black-white, black-white-etc. from left to right, going into the meter itself.

Make sure that the CT on hot line 1 is connecting in to ports 1 and 2 on the meter, and not 3 and 4 , etc.

Here is a video showing proper wiring of a 120/240 volt 3-wire system:

Make sure that the neutral wire is connected and tight. A loose neutral connection will cause the meter to measure improperly.

If you are still having trouble please send us clear photos of the wiring and/or the data from either your EKM Dash or EKM Push system (if you have your meter connected)

Note that once you have it working correctly the existing Reverse kWh will not go away — just not increment any further.

Note also that even if you do have reverse kWh and it matches your Total kWh then your Total kWh is very likely still accurate!
