The wire is shielded and a twisted pair of 1mm wire about 25 - 30 m. That reading is when the wires are unplugged. The clamp is on the incoming supply from grid to my non essential loads. The new pic is when the wires are connected in 3 and 4 of my 5k Sunsynk.
I am getting a negative watt reading on the CT before the CT wires are even plugged in. When the CT is plugged in I get positive readings but it seems to under read what is really being drawn from the grid. This is all resulting in me using a lot more power than I should be. Does anyone have any idea what could be causing this kind of interference?
