CT’s for Eastron meter
Hi
Can you use the CT’s that come with the inverter for the Eastron SDM630MCT meter? My 12kW 3ph inverter came with 3x 100A/50mA CT’s. I can’t seem to change the ratio on the Eastron meter and the meter does not pick up any amps. Any advise?

This document should help with the setup of the meter.
This should help you. However the document shows Set Ct 2 as 1A and Set Ct1 as 0150. This means the CT ratio would be 150A/1A (as supplied by Sunsynk). I have also used 100A/5A CT which means you have to se Ct 2 to 5A and Ct 1 to 0100A.
The meter you have does not support the 100A/50mA
Also I have use this type of meter and it kept producing the W04 event quite frequently. It did not stop the inverter from working, I have now replace it with an Easton meter from Sunsysnk. It is just labeled SDM630MCT. Not sure what the difference is.
