FoxEss T25 G3 series problem with Chint smart meter DTSU666CT
Posted: Thu Mar 16, 2023 9:05 pm
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!
