Trickle feed and real grid consumption
So on my 8kW inverter, with 10kWh batteries and 5kW solar, I noticed some funny consumption from the grid.
When the battery has enough capacity and/solar is generating sufficient to supply the load, the trickle feed is set at 50W so as not to export.
I noticed that the CT shows say 50W, load is being supplied by solar or battery, but if check the incomer with a different CT or meter, there is 300W or so being imported.
Why is the inverter drawing more than the 50W trickle feed? Anyone with ideas, ? Is there another setting?
The CT is connected to the incoming phase from the grid.

Is your CT_ratio setting under Advanced Settings correct (mine is set to 2000 with a 5kW inverter)? I will need to check with an external meter, but my inverter reading for grid draw match what my conlog meter uses in a day, so can't be too far off... Also, check the pdf for ratio details here: https://www.sunsynk.org/post/using-a-ct-coil
