Hi to all !

Read and searching here for similiar problem but didn't find anything......

So I have fitted Chint dtsu666-CT (with ct's) , not regular in line dtsu666

I have strange readings....

In parameter I set CT ratio to 40, because ct's are 200A / 5A (=ratio 40........ok?)
And Ct's are in good position ....between House load / PV and Grid....and arrows are turned to house....

Phases are also correct A /B /C phase with A / B / C transformer

But I have odd readings, when PV production grow, also Load of house grows......PV product 12.5kw, Load is 9.2kw and 3.3kw "going to grid"
But I don't have 9kw consumption in house

It's seems to me that the box "Grid" is consumption of house, and box "Load" is actually grid.......is this possible?

oh, and I tryed to reverse the ct's arrows......then I have pv load 12.5 kw (ok)...... Load/consumption of house is 15.8 kw! and taking from Grid is 3.3kw....


Don't know what to do anymore 😓

Does anybody maybe have some solution?

Greeting!
