14.1. Q1: I cannot switch my Multi/Quattro system on or off
To solve the problem, first find out how the system is connected, and then follow the right step by step instruction below. There
are two ways to connect a Multi/Quattro system to a Color Control GX. In most systems they will be connected directly to the
VE.Bus port on the back of the CCGX. And, option two, in some systems they are connected to the Color Control GX using
a
.
Step by step instructions when connected to VE.Bus port on the CCGX
1. Update the Color Control GX to the latest available version. See our blog posts in the
https://www.victronenergy.com/blog/
.
2. Do you have a Digital Multi Control or VE.Bus BMS in the system? In that case it is normal that on/off is disabled. See also
the VE.Bus related notes in the
3. In case you have had a Digital Multi Control or VE.Bus BMS connected to your system, the Color Control GX remembers it
and even when those accessories have been removed the On/off switch will still be disabled. To clear the memory, execute a
Redetect system, the option is in the Multi or Quattro section of the Color Control GX menu.
4. For parallel/three phase systems consisting of more than 5 units: depending on temperature and other circumstances, it might
not be possible to switch a system back on after switching it off with the CCGX. As a work around you'll need to unplug the
VE.Bus cable from the back of the CCGX. And plug it back in after starting the VE.Bus system. The real resolution is to install
the “CCGX dongle for large VE.Bus systems”, partnumber BPP900300100. For details, read its
Step by step instructions when connected to CCGX via VE.Can.
1. Update the Color Control GX to the latest available version. See our blog posts in the firmware category.
2. Update the VE.Bus to VE.Can interface to the latest version. The easiest way to do that is by using Remote firmware update:
having a special piece of hardware, the CANUSB, is then not necessary.
3. Do you have a Digital Multi Control or VE.Bus BMS in the system? In that case it is normal that on/off is disabled. See also
the VE.Bus related notes in the CCGX manual
4. In case you have had a Digital Multi Control or VE.Bus BMS connected to your system, and it is now no longer connected, the
Canbus interface remembers it. Therefore, even after those accessories have been removed, the On/off switch will still be
disabled. Clearing this memory is unfortunately not possible yourself, please contact us so we can help you.
14.2. Q2: Do I need a BMV to see proper battery state of charge?
.
14.3. Q3: I have no internet, where can I insert a sim-card?
There is no 3G modem in the GX Device, and therefore also no slot for a sim-card. Go to a local store and buy a 3G router with
Ethernet ports. More information in the blog post link below and particularly in the comments section, as more users try differing
equipment:

Note that it is not possible to use a VGR2 or VER for this. Also it will not be possible in the foreseeable future.
14.4. Q4: Can I connect both a GX Device and a VGR2/VER to a Multi/Inverter/
Quattro?
No. Also, instead of this combination, we recommend to use the Color Control GX, and add a 3G or similar mobile router. See
.
14.5. Q5: Can I connect multiple Color Control GX to a Multi/Inverter/Quattro?
No.
14.6. Q6: I see incorrect current (amps) or power readings on my CCGX
Examples are:
• I know that a load is drawing 40W from the Multi, but the CCGX shows 10W or even 0W.
• I see that the Multi is supplying a load with 2000W, while in inverter mode, but from the battery only 1850W is being taken. Is
those 150W coming out of nowhere?
