18.2. FAQ
18.2.1. 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
VE.Bus to VE.Can
interface.
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/category/firmware-software/.
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 in the Remote Consolemenu for your Multi or Quattro.
For details see he
tAdvanced menu [56]
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.
18.2.2. Q2: Do I need a BMV to see proper battery state of charge?
It depends. For details see the
Battery state of charge (SoC) [44]
18.2.3. Q3: I have no internet, where can I insert a SIM card?
There is no 3G or 4G modem in the GX device, and therefore also no slot for a SIM card. Go to a local store and buy a 3G/4G
router with Ethernet ports. More information in the blog post link below and particularly in the comments section, as more users
try differing equipment:

18.2.4. 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/4G or similar mobile router. See
Internet connectivity
[29].
18.2.5. Q5: Can I connect multiple Color Control GX to a Multi/Inverter/Quattro?
No.
