[Solved] 18kPV CTs not detecting Consumption

I’m setting up my EG4 18kPV in a very simple grid-tie configuration with the inverter connected to a backfeed breaker.

I connected the included CTs to the CT 1&2 port on the inverter and clamped them on my 2/0 copper L1 and L2 mains with the arrows pointing toward the inverter (backfed breaker on the inverter). The system shows 0 W house usage, even after multiple restarts and reversing CT direction.

Using a clamp meter, each main is pulling about 8 A (16 A total), so the CTs should definitely be reading current.

Here is a picture of the relevant CT setting on my 18kPV. Is something wrong here?
