Hi
We have a customer who has these Victron Multiplus Quattro inverters to provide power for their buildings. I was wondering if/how we can get Modbus TCP data from this device?
Regards
Mike

Modbus TCP from Multiplus Quattro?
If you haven't already found it, below is a link to the Victron Modbus TCP FAQ

The easiest way is to add a Victron Venus Device to your system. (CCGX, Venus GX, etc.). They communicate with the Quattros and have a built-in Modbus TCP slave functionality. You can then read/write the information from any external Modbus TCP client.
That's what I did with my system.

Forgot to add: You can download the Venus Modbus TCP registry list from here:

I want to access quattro ccgx on my laptop window 10 through modbus how can i do it??
I also want to moniter status of each device connected to ccgx?
Main thing is how to establish connection between ccgx and laptop through modbus-tcp ccgx already connected with quattro.
You say add ccgx on your computer.I am confuse how can i add ccgx to my laptop
thanks in advance
You will have to connect the CCGX to your local ethernet LAN using a Cat5e UTP cable with RJ45 connectors. Then you will need software on your laptop that acts as a Modbus TCP client.
Assuming you are using a Windows laptop you can test and query individual modbus registers with an application called AVReporter or similar. To perform logging, monitoring or control you will need a SCADA (Supervisory Control and Data Acquisition), with modbus TCP support, application on your laptop.

thanks pat davitt in this software firstly connected laptop with ccgx by giving ip and port number.
secondly i want moniter things can i get status like writing 824 register no on register box and click on calculate ?? thanks
If you don't want/ have a venus GX device, you can simply use a MK3 and use this python script:
