Multiplus shows Off on Colour Control after firmware update on Multiplus

Good day.


We installed a Victron Multiplus 48/5000/70 with a Color Control GX and MPPT 250/60.


After updating firmware on Color Control and Multiplus the inverter shows Off on display of color control. The MPPt and battery do come up on display on Color controller but no Multi plus.

There are power on the inverter and works as normal with correct outputs. It's clearly a VE.Bus conflict. Are there any way to hard reset the Color Control?

Hi, did you solve the problem? I do have the same problem with a three-phase Multiplus II 48/5000. It appeared in the Color Control the first time but now it desapear and I cannot detect the Multiplus II in the Color Control anymore. How did you sole it if you actually did?

I had to do it a few weeks and its quite hard to find

I dug through the menus until I found It.


I have not got a CCGX near me as I cant remember the exact spot

Hi Paul where do I do the detection on the CCGX. The Multi plus selection does not come up.

Ironically, and unhelpfully, the detect system options are in the Multiplus menu, which is not appearing for you.

Another thing I have noticed on my own system which is a multipus 48/5000 as well is if you still have a MK2 connect then this off on the CCGX shows.


another thing is upgrade the Multiplus firmware to the latest 433 version. may help you never know

mine was on 430 so have upgraded it to 433

Try pressing the two top buttons simultaneously, and then releasing them.

I had tried that multiple times with no luck.


Can you post a picture of what you are seeing?

Inverter not connecting to Color Control

That all looks good (except for the missing multi).

Can I get a photo of both data connections on the back of the CCGX and the multi?

Be careful, as the connections are close to live terminals.

Back of Color control and Multi connection

Have you tried swapping ve.bus ports on both, and a different Ethernet cable?

Also is the inverter actually on and inverting? It looks like the inverter light is off?
