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?
Obviously, I have not connected the inverter to the breaker yet as I want the CTs to be properly measuring current before doing so. Is this part of my issue?
