Fox R100-G2 and CHINT DTSU666 smart meter error code 1285

[VakiNaki]

Hello team

I use the Fox R100-G2 inverter ON GRID and I also use the Zero export option, I do not use batteries

I am trying to eliminate the code -1285 error on my inverter. The Chint DTSU666 is connected to the R100-G2 inverter by connecting the smart meter pins 24 and 25 to the smart meter inverter pins 6 and 7.

In the Chint DTSU666 settings I set
CT= 40 (I use clamps 200:5)
Addr=1
baud=9600
nEt=n34
Pt=1.0
Prot=n1
In the inverter settings
quick settings/R&D(Others)
GridMeterCommunicationCheck=enable
SolarMeterCommunicationCheck=enable
MeterCommunicationCheck=enable
CTRatioEnable=enable
CTRatio=40 (1-9999)
I don't know what I'm doing wrong




If I set it to export limit in the quick settings
Export limit settings
PowerLimitOfGridFeeding=Disable
PowerLimitPrecentOfGridFeeding=100.0 (0-100)%
ExportLimit=0 A
It looks like I'm exporting, and I use the zero export option and it doesn't show me the consumption in my house
