Hi,

I am using a multiplus system in a 3 phase system. everything works well, except my SDM630 and modbus TCP system. I used this page to get the multiplus working with the SDM630 connected to a modbus tcp… Eastron SDM630/SDM230 Modbus Energy Meter - community edition - VictronEnergy I have used this modified SDM630 python file:
Eastron_SDM630v2.py.txt (2,9 KB)

Why doesn’t it work? It can’t find the SDM630. Do you know how to get the SDM630 with modbus TCP interface working with the multiplus?

Best regards,
Mark

Never heard, that the old SDM630 is compatible with victron…
At least it is not mentioned in the list for compatible meters like EM24, ET340, etc…

I had a SDM630 some years ago and changed it to a EM24 when I installed my Victron ESS, because one point is the connection itself, but the other part is also the “counting method” the meter is using. Don’t know if the SDM630 is accurate enough.

I have solved the problem with the SDM630. SDM630v2 has a standard setting of modbus address 1. SDM630v3 has a standard setting of modbus address 2. Guess which one I used? Yes, SDM630v3. Standard passcode is 1000 for the ones who need it. I recommend the HE11 Modbus TCP interface. I have the HE11-H (230VAC powered). Easy to integrate in your fuse box.
The SDM630 has 2 versions. a cheaper version and only slighty more expensive MID version.I recommend the MID version. I want to use the SDM630 instead of the EM24. Why? at the moment I am using a SDM630 in my system with Modbus TCP. This way the cerbo GX can get the information, but also home assistant.

This is a link to the files you need on the cerbo GX: GitHub - M-o-a-T/victron-meter-library
