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.

If you don't want/ have a venus GX device, you can simply use a MK3 and use this python script:
