Measured numbers don't add up - 100% of PV Gen going to Consumption Power

I noticed my PV power generation was 496W and I was consuming 703W but nowhere does it show where the other 207W is going.

I know there is an adjustment for the CT units for what's going to/from the grid but these things are being measured internally:

PV 1-3, Load, Gen AC-coupling and Battery.

Right now, my batteries are putting out 435W while my Load is consuming 572W.

Where are the CT's located?
I would recommend making sure they are connected and placed properly. 

It could be using the grid but there could be something missing and the inverter is not getting any data from the grid.

They are on the input to the grid breaker before the 18KPV. I originally had them inside the 18KPV box but was told that can sometimes be noisy so I moved them.

I don't think it would be the CTs although we do dribble 2kWh per day into the grid. Which equates to .07 kWh/hr according to the grid operator.

I also understand the inverter eats ~70W.
