June 3, 20224 yr Please, any advise really appreciated here. Looking at the manual for the CHNT External Meter it looks like the meter is installed between the Grid and the Inverter. Based on the image from the manual below, it doesn’t seem to me that the meter can replace the function of the CTs and CTs are still required to control the power fed back into the home and to control the export onto the grid? Has anyone got advise on this and if they were able to replace the standard CTs with a CHNT DTSU666 meter at the main grid connection for your house. Or are the CTs always required for the SunSynk to work effectively in a grid-tied environment? My application is that I have various DB boards and need to measure the overall load from the grid connection point which some distance away from the inverter (30m+). So would like to use the CHNT Meter at my grid metering point for best accuracy rather than CTs with 30m long cables.
September 27, 20232 yr Hi Bryan, Did you ever get any more information on this? I'm busy with a similar install with 2 x 12kW 3ph inverters in parallel, and have just installed the CHINT meter, but had some strange readings, so want to check with someone who might have done this installation sucessfully.
September 27, 20232 yr The Meter is installed in between the inverter and the HOUSE's own energy meter. So the meter would be the FIRST device connected after the main fuses and before ANY consumers on the house. Same place would you install CT coils if you do not want to use a meter. When installing a meter , no need for CT coils.
September 13, 20241 yr Hi there, would you know the pin config on the inverter side? Sunsynk 12kva 3 phase.
