Hi everyone!
Does the distance between your grid mains incomer and inverter exceed 10 meters, resulting in inaccurate power readings? Don't worry! We have a solution for you: installing an EASTRON meter extends the connection distance and ensures precise readings.
These EASTRON meters can be provided by your wholesaler. It is essential that the model number is SDM120CT, as this should come with a CT clamp featuring a 120A/40mA ratio. Using any other EASTRON meter may result in potential inaccuracies.
Contact your wholesaler directly to get the right meter and enjoy accurate power monitoring for your solar power system!

Hi there
Will the Eastron SDM630MCT-Modbus-MID 3 phase meter work with the 12kW 3 phase inverter?
The SDM630RTM V2 meter is only for single phase, 1 CT and not 3 CT’s.
Please advise
Hello Georgia,
Is there a 3phase equivalent of this meter. We are really struggling with our large 3phase installs especially when we have a 300A+ supply. Current install has a mains supply of 0.4MVA and the CT mentioned here will suffice. We have also been trying to get the Chint DTSU666 meter working but also without success.
Any help would be greatly appreciated.
Hi All, I was going to order a SunSynk hybrid for an installation this week - but this CT Distance limitation is causing me headaches. I'm replacing a Sofar inverter, where the existing CT is wired via Cat5 directly into that inverter ... reading below i understand the limitation, but here in the UK i'm finding it difficult to find these exact Eastron components.
Last comment was some time ago - so before i explore further, i just wanted to see if this is still the recommended solution - and if there is an alternative meter/clamp combination thats been validated.
In my case, i think the CT is in the region of 35m or from the Inverter.

Yep, it’s the meter port, tech help desk got back to me
Can I have confirmation what port this plugs into on the inverter please. Initially I thought it was the RJ485 port (not that my inverter has one as I found out today - I've got the 2-in-1 that is used to connect to the batteries).
However, should the Eastron be plugged into the meter port? (port is not detailed in the instructions).
