Good morning chaps,
I am just after a bit of help/advise. I have just finished installing a Victron Multiplus in a motorhome conversion. It is installed alongside a 70a MPPT solar controller and all are wired to a CCGX. I recently upgraded the firmware in the CCGX as the multiplus and ccgx were previously in a household setup and they have been stored over a year since I purchased them used.
The MPPT shows in the CCGX via the VE Direct cable and that shows fine, showing the solar input, battery voltage etc.
The issue is that the CCGX does not show when the Multiplus is turned on, it shows a symbol for a Multiplus but it always shows off, even when the inverter is on and powering appliances. The Multiplus is connected using one of the blue bus cables to the VE BUS input on the back of the CCGX and I have tried it plugged in to both connectors in the Multiplus but nothing shows up as working. The Multiplus also and has a temp sensor that is connected from the Sensor connection in the Multiplus to the negative terminal of my battery bank (this all came as a used setup kit other than the mppt).
Should it be a case of just plugging in the blue network cable in both the Multiplus and CCGX and it should all display as connected and working? I presume I am correct with the temp to the negative?
The setup and install is pretty much complete, I just want the Multiplus to show on the CCGX as everything is getting boxed in very soon so wouldn't want to have to rip everything out to change a cable etc....
Attached is a pic of the CCGX, I can take more pics of the back and cabling if required.
Can anyone help out here with some info or advise to get the Multiplus showing on the CCGX?
