How to use more than 2 MPPTs with Byd and CCGX on ve direct/usb

Just wanting to put this one out


Colour gx, byd, Bmu 3 smart mppt’s


The colour gx only has 2 ve direct ports so is it safe to say the ve direct to usb lead can be used for the 3rd mppt and not cause any issues?

Correct!

You can safely use the VEdirect to USB converter to increase the number of controlled MPPT’s (or other VEdirect devices) to a total of 5(ish) on the colour control.

There are 2 USB ports available on the back of the CCGX. If you need another, you will need to use a powered USB hub.

To add: see here for max number of mppts that can be added:

And see the manual for more information on the initial question; it has a long chapter detailing all ways to connect products to the CCGX.

Hi Guy,

latest training there is no wiring diagrams for the use of a BMV 700 shunt for use of BYD

I have 2 mppt 250/60 solar chargers, multi plus 5000, and Byd cabinet with 2 batteries with colour control all mounted together. I also have a high power usb wifi adaptor for colour control and a basic usb hub not powered but only 4 ve direct cables with no, usb .

how can I connect ve connect cables to charges, bmv and colour controller.

Can this work with out with out a usb hub or

should I connect usb hub supply from from colour controller to connect my three items

by ve direct from usb.

This was happening a lot on my personal install. Make sure you have the latest version of firmware loaded on the MPPT's as this was a known bug that was fixed.

I have also an industrial USB hub (powered) running 5x MPPT's and this has worked fine for the last six months through a CCGX.

I noticed Victron have released a new unit cable of running x10 MPPT's.

This very helpful. Thank you guys.

Another question though; so I have to connect 2 MPPT controllers to my CCGX. How do I do that, since the CCGX has only 2 VE.Direct ports? I have 2 MultiPlus, and a BMV-702 to connect to the CCGX as well.

Thanks
