The Color Control GX (CCGX) sits at the heart of your energy installation. All the other system-components - such as inverter/chargers, solar chargers, and batteries - are connected to it. The CCGX ensures that they all work in harmony.
Monitoring can be done either with the CCGX in front of you - or from anywhere in the world using an internet connection and the VRM Website
The CCGX also provides Remote firmware updates and even allows the settings to be Changed Remotely.
The Color Control GX is part of the GX product family. GX products are Victron's state-of-the-art monitoring solution that run our VENUS operating system.
All the information in this manual refers to the latest software. Your device will update itself to the latest version automatically. Check our blog posts to see that your device has the latest firmware:https://www.victronenergy.com/blog/category/firmware-software/
In order to reduce Electromagnetic emissions in compliance with class B EMI you should place the provided snap-on ferrite beads around every connection cable as close as possible to the Color Control.
Power the device using the Power in V+ connector. It accepts 8 to 70 V DC. The device will not power itself from any of the network connections. Be sure to use a 1A slow blow fuse.
When the CCGX is used in an installation with a VE.Bus BMS, connect the Power in V+ on the CCGX to the terminal labelled 'Load disconnect' on the VE.Bus BMS. Connect both negative leads to the negative stub of a common Battery.
If you power the CCGX from an AC adaptor connected to the AC-out port of any VE.Bus product (Inverter, Multi or Quattro), then a deadlock will occur after the VE.Bus products are powered-down for any reason (after any operational fault or during a black start). The VE.Bus devices will not boot-up until the CCGX has power …but the CCGX will not boot-up until it has power. This deadlock can be rectified by briefly unplugging the CCGX VE.Bus cable at which point you will observe the VE.Bus products will immediately begin to boot-up.
Or a modification can be done to the RJ45 cabling. See FAQ Q21 for more information about this.
Because the CCGX is connected to many different products, please ensure that proper care is taken with isolation to prevent ground loops. In 99% of installations this will not be a problem.
Although the number of USB ports can be extended by using a hub, there is a limit to the amount of power that the onboard USB port can provide. When extending the number of USB ports, we recommend you always use powered USB hubs. And to minimize the chance of issues, be sure to use good-quality USB hubs. As Victron also offers a VE.Direct to USB adapter, you can use this arrangement to increase the number of VE.Direct devices you can connect to your system, please see this document for the limit of how many devices can be attached to various different Venus-Devices.
In order to keep this document short we are going to refer to all Multis, Quattros and Inverters as VE.Bus products.
The earliest version of the VE.Bus devices which can be connected to the CCGX is 19xx111 or 20xx111, which were released in 2007. VE.Bus firmware 26xxxxx and 27xxxxx are also supported …but 18xxxxx is not.
Note that it is not possible to use the Remote On/Off (header on the VE.Bus control PCB) in combination with a CCGX. There should be wire between the left and middle terminal, as it is when shipped from the factory. In case a wired switch that disables the system is required, use the Safety Switch Assistant.
Single VE.Bus products
To connect a single VE.Bus product, connect it to one of the VE.Bus sockets on the back of the CCGX. Both sockets are identical, use either one. Use a standard RJ45 UTP cable, see our pricelist.
Parallel, split- and three-phase VE.Bus systems
To connect multiple VE.Bus products, configured as a parallel, split-phase or three phase VE.Bus system, connect either the first or the last VE.Bus product in the chain to either one of the VE.Bus sockets on the back of the CCGX. Use a standard RJ45 UTP cable, see our pricelist.
Systems consisting of five or more VE.Bus products, connected to a CCGX with serial number HQ1628 or earlier require the 'CCGX dongle for large VE.Bus systems (Product Number: BPP900300100).
VE.Bus systems with Lithium batteries and a VE.Bus BMS
Combining the CCGX with a Digital Multi Control
It is possible to connect both a CCGX and a Digital Multi control to a VE.Bus system. The ability to switch the product On, Off or set it to Charger Only via the CCGX will be disabled. The same applies to the input current limit: when there is a Digital Multi Control in the system, the input current limit which is set at that control panel will be the master-setting, and changing it on the CCGX will not be possible.
Connecting multiple VE.Bus systems to a single CCGX
Only one VE.Bus system can be connected to the VE.Bus ports on the back of the CCGX. The professional way to to monitor more systems is to add a second CCGX.
If you do require to connect more than one system to the same CCGX, use an MK3-USB. Functionality will be limited:
Alternatively the VE.Bus to VE.Can interface (ASS030520105) can be used. Add one for each additional system. Note that we advise against it; this interface is a deprecated product. Make sure that the VE.Can network is terminated and powered. For powering the VE.Can network, see Q17 in our data communication whitepaper.
Either one or two compatible products can be connected directly on the back of the CCGX using a standard VE.Direct cable. There are two types of VE.Direct cable available:
VE.Direct cables have a maximum length of 10 metres. It is not possible to extend them. If longer lengths are required, use the VE.Direct to VE.Can interface. Note that this only works for BMV700 and BMV702. Not for the BMV712, MPPT solar chargers and Inverters with a VE.Direct port. See next paragraph for more information on that VE.Can interface.
Connecting more than two devices to your CCGX using VE.Direct
First of all, note that the maximum of VE.Direct devices that can be connected is 5 for the CCGX. How they are connected, so direct, via USB or via CAN, does not change the maximum. See here for the Venus GX, Octo GX, and other limits.
Notes about older VE.Direct MPPTs
To connect a product with a VE.Can port, use a standard RJ45 UTP cable. (Available with straight and elbow connectors)
Connect the BMV-600 using the VE.Direct to BMV-60xS cable supplied. (ASS0305322xx)
Connect the DC Link box, using the RJ-12 cable supplied. Then connect the BMV-700 to the CCGX - see 1.2.2 above for instructions.
See its page and manual on our website for details about the Adapter.
To connect a product with a VE.Can port, use a standard RJ45 UTP cable.
Don't forget to terminate the VE.Can network on both ends using a VE.Can terminator. A bag with two terminators is supplied with each VE.Can product. They are also available separately (ASS030700000). (Available with straight or elbow connectors.)
Make sure that the canbus is powered, see the Power chapter in the Tank Sender Adapter manual for details.
A tank sender must meet the following requirements to be visible on the CCGX:
Since v2.17 the following functions are accepted as well:
A single function reporting multiple Fluid Levels is currently not supported.
For some tank senders it is also possible to configure the capacity and the fluid type from the CCGX - for example the Maretron TLA100. This facility may be available with other senders made by other manufacturers - it's well-worth trying.
To connect an NMEA2000 network to the VE.Can port on the CCGX, use a VE.Can to NMEA2000 cable.
Alternatively, instead of a VE.Can to NMEA200, you can use a 3802 cable from Oceanic Systems: https://osukl.com/ve-can-adaptor/. The difference is that it lends itself well to connecting a single NMEA-2000 device into a VE.Can network. It's also able to power a lower voltage NMEA-2000 network directly from a 48V Victron system.
Measuring the output of a PV Inverter will provide the user with an overview of both actual power balance and the energy distribution. Note that these measurements are only used to display information. They are not needed, nor used, by the installation for its performance.
There are several ways to get the system to show the output of a PV Inverter:
Connect the CCGX to the internet to get all the advantages of the VRM Portal. The CCGX sends data from all connected products to the VRM portal - from where you can monitor energy usage, view the current status of connected products, configure email alarms and download data in CSV and Excel formats.
To monitor this data from your smartphone or tablet download the iOS or Android VRM App.
In addition to remote monitoring, an active internet connection allows the CCGX to regularly check for a new firmware versions - which will be automatically downloaded and installed.
There are several ways to connect a CCGX to the internet:
The chapters below describe these options in detail.
When you connect an ethernet cable between a router and CCGX, the Settings>Ethernet page of your CCGX will confirm connection.
Using a Wi-Fi dongle it is possible to connect to WEP, WPA and WPA2 secured networks. There are four supported USB Wi-Fi dongles. Two of them are also available from stock at Victron Energy:
New model coming early 2019: Asus USB-N14, slightly higher cost and also better reception. Victron part number: BPP900200300. Requires a firmware version not released yet.
Although other Wi-Fi dongles may work, they have not been tested and we do not offer support for other dongles.
The Wi-Fi menu shows the available networks. When a network is selected, it is possible to fill in the password (if the password is not already known) to connect to the network. Setting up via WPS (Wi-Fi Protected Setup) is not supported.
When the CCGX finds multiple Wi-Fi networks of which the password is known, the strongest network is selected automatically. When the signal of the connected network becomes too weak, it will automatically switch to a stronger network - if it knows the password of that network.
To connect the CCGX to a mobile (cellular) network, such as a 3G or 4G network, use a cellular router. Connect the CCGX to that router with either a LAN cable or the router's Wi-Fi network.
Make sure you use a router that is designed for unattended setups. Do not use low cost consumer-grade routers intended for business or leisure travel. A more expensive professional router will quickly pay for itself, and you won't have wasted journeys simply to perform a re-set. Examples of such professional routers are the H685 4G LTE from Proroute, as well as the Industrial 4G router range from Pepwave.
More information in this blogpost.
Note that the CCGX does not support USB 3G/4G dongles.
This is a useful facility when it works - but don't rely on it because it has not proved very dependable. Consult the internet for instructions about tethering for your phone and its particular operating system. We have heard of it working on:
…but not on:
Almost no installations will need the IP address configuration to be inserted manually as most systems support automatic IP configuration (DHCP) - and that is also the CCGX default setting. If you do need to configure the address manually, select the following template:
Complete details of IP requirements, as well as used port numbers will be found in the VRM FAQ - ports and connections used by the CCGX.
It is possible to connect the CCGX to both Ethernet and Wi-Fi. In this case, the CCGX will try to determine which interface provides an active internet connection and then use that interface. When both have an active internet connection, the Ethernet connection is used. The CCGX will automatically check again for active internet connections when something changes on the interfaces.
In situations where internet traffic is expensive, for example a satellite uplink or with roaming GSM/cellular charges, you may want to minimize the internet traffic. The steps to take are:
To find out how much data allowance you need to buy the best way is to let the system run for a couple of days and monitor the internet RX and TX counters in your 3G or 4G router. Or even better, some mobile companies will report the data used via a website.
The amount of data used is also very dependent on the system:
Note that CCGX versions prior to v1.18 will check for software updates daily even when auto-update is switched off. This was changed in v1.18. Disabling auto-update also disables the check - saving a lot of data.
We recommend setting-up your data plan in such a way as to avoid costly 'excess' charges. Make sure you put a cap on your data usage; or use a pre-paid plan.
One customer - burdened with global costs of between twenty cents and several euros per mb of data - invented a clever solution: Using a VPN he modified the IP to route ALL traffic to and from the CCGX via his VPN. Using a firewall at the VPN server allows him to control traffic according to time, connection type, place and destinations. Although this is beyond the scope of this manual it works, and - with the help of a Linux and networking expert - it can work for you.
Use a GPS to track remote vehicles or boats and, optionally, get an alarm when they leave a designated area (geofencing). It is also possible to download a gps-tracks.kml file which can be opened with Navlink and Google Earth for example.
Victron does not sell USB-GPS, but the CCGX will support third-party GPS modules which use the NMEA0183 command-set - almost all do. It can communicate at both 4800 and 38400 baud rates. Plug the unit into either of the two USB sockets …connection may take a few minutes, but the CCGX will automatically recognize the GPS. The unit's location will automatically be sent to the VRM online portal and its position shown on the map.
The CCGX has been tested for compatibility with:
After completing the installation and setting up the internet connection (if required), go through the menu from top to bottom to configure the CCGX:
|Remote support||Off||Enable this to allow Victron engineers to access your system in case there is a problem.|

|Enable password check||Choose password to allow remote console access.|
|Enable on VRM||No||Enabling on VRM will allow connection to the CCGX from anywhere via the VRM portal. Trouble shooting Remote Console on VRM|
|Enable on LAN||No||Enabling will allow direct connection to the CCGX by typing it's IP address into a web browser. Only Enable this function on trusted networks.|
|AC input 1||Generator||Select Generator or Grid. (We will shortly be adding the setting 'Shore power' instead of grid.)|
|AC input 2||Grid||Same choices as above.|
|Battery monitor||Automatic||Select the SOC source. This function is useful where there is more than one BMV. More details.|
|Synchronize VE.Bus SOC with battery||Continuously copies the SOC from the battery monitor to the VE.Bus system. This feature is automatically enabled when the active SOC source is not a VE.Bus device, and there is no Hub-2 Assistant configured. The purpose of this is to be able to use the BMV SOC to trigger some Multi or Quattro features - such as Genset start/stop. Multis and Quattro's don't use the SOC for any other purpose. More information|
|Use solar charger current to improve VE.Bus SOC||Send the total charge current from all connected Solar chargers to the VE.Bus device to improve its SOC computations. This feature is automatically active when 'Synchronize VE.Bus SOC with battery' is not active. Requires Multi Firmware version >= 402. More information|
|Solar charger voltage control||Use the 'charge voltage' information provided by the VE.Bus device to control the amount of power fed from solar chargers back to the grid. Active if the ESS or Hub-1 assistant is present. (See also: 'Feed-in excess solar charger power' in the ESS settings.)|
|Solar charger current control||Limit the charge current of the connected solar chargers if a CAN.bus BMS is present - using the maximum charge current information provided by the BMS.|
|Has DC system||No||Enable this for boats, vehicles and installations with DC loads and chargers - in addition to Multi and MPPT chargers. This won't be applicable to most off-grid installations; and any discrepancy between the DC current measured by the Multi, and by the BMV, will be attributed to a 'DC system'. This may be power-in from an alternator, or power-out from a pump, for example.
A positive value indicates consumption. A negative value indicates charging, for example by an alternator.
Note that the value shown will always be an approximation, and is affected by the variation in sample rate between elements of the system.

When using a VE.Bus system, it is possible to configure the severity of problems on the VE.Bus system that should cause a notification to show up on the CCGX (and make it beep):
When all done, don't forget to change the access level to user when required.
Click the thumbnail below to see the complete menu-tree:
The CCGX can be used in combination with the Victron Remote Management (VRM) portal: The CCGX monitors all products connected to it and the VRM portal makes the statistics easily accessible.
Since version 1.40, dealing with an absent or intermittent internet connection has changed. Data is sent out via the Internet if it's available, and will fall back to non-volatile storage when there is a (temporary) Internet outage. The built-in non-volatile storage can contain 48 hours worth of data. To extend this period, one can insert an microSD card or USB stick, and the CCGX will automatically transfer any data that may reside on the internal storage to it, and will start using this external memory as backlog buffer. You can see that it's active in the settings menu:
When using this external memory, it will still make use of an active internet connection to send its backlog. That means that even with months worth of backlog, once the CCGX re-acquires an Internet connection, all of the backlog is sent out. And because of an enhanced algorithm, this takes considerably less time and traffic than before.
When a CCGX is permanently without Internet, one can choose to upload the backlog buffer manually. The first step is to use the GUI (Graphical User Interface) to eject the storage (don't just remove the SD-card/USB-stick). The storage device can then be removed from the CCGX and inserted into a computer or laptop, the data file on it can be uploaded on the VRM Portal with the 'Upload CCGX File' option:
It's important to know that when the microSD card or USB stick is re-inserted, the existing buffer - including its data - is used again. This allows for removing the microSD card temporarily for whatever reason, but this also means that when the data file has been uploaded to VRM, it needs to be renamed or cleared from the microSD card / USB stick before re-inserting, otherwise the data will be transmitted again, sooner or later, on-line or off-line.
Because of the aforementioned improvement in sending of backlog data, the data logging is also highly resillient to bad internet connections. Lines of up to 70% permenant packet loss are still sufficient to get the data out, albeit somewhat delayed.
With a log interval of once per minute, the required storage space roughly amounts to about 25 MB per month, depending on the number of connected products. So with a 1 GB microSD card, you can store about 3 years of backlog. In other words, any microSD card or USB stick should be sufficient to store the 6 months of data which VRM retains.
When the storage device is full, no more data will be logged. This is due to the nature of Sqlite files. Removing data from the Sqlite database doesn't free-up usable disk space; and because of internal fragmentation, it doesn't guarantee more data storage.
If both a microSD card and a USB flash drive are connected to the CCGX, then data is logged to the one that was inserted first. If one is removed, the CCGX will not try to write to the other, but will create an internal backlog buffer until a new storage medium is inserted when it will use that storage medium.
This chapter explains the implications of enabling or disabling user control of the input current-limiter setting, as seen here in the menu:
The limit as set by the user in the CCGX will be applied to all inputs where 'Overruled by remote', configured with VEConfigure, is enabled:
Using the example of a boat with two AC inputs and a Quattro where:
Configure the system exactly as in above VEConfigure screenshot. Input 1 has priority over input 2, therefore the system will automatically connect to the genset whenever it is running. The fixed input current limit of 50A will be applied. And when the genset is not available, and mains is available on input 2, the Quattro will use the input current limit as configured in the CCGX.
Two more examples: (In both cases if you disable 'Overrule by remote', setting a current limit in the CCGX will have no effect. And if you enable 'Overrule by remote' for both inputs, the current limit set in the CCGX will be applied to both inputs.)
It is not possible to control the input current limit in certain installations. In these cases, the CCGX menu will not allow changing the setting:
Also the on/off/charger only switch in the CCGX will be disabled in the case.
In installation with a VE.Bus BMS, use the rocker switch instead - or add a Digital Multi Control to the installation.
When PowerAssist is enabled in VEConfigure, there is a minimum input current limit. The actual limit differs for each model.
After setting the input current to a value below the limit, it will automatically be increased again to the limit.
Note that is still possible to set the input current limit to 0. When set to 0, the system will be in passthrough (charger disabled).
The configured input limit is the total limit per phase.
There are three products types that calculate State Of Charge (SOC). The CCGX itself does not calculate SOC, it only retrieves it from the connected devices.
The three products that calculate SOC are:
When to use what?
If you have a battery with build-in battery monitor, such as a BYD or Freedomwon battery; its easy. Use that.
If the MultiPlus or Quattro inverter/charger is the only source of charge to the batteries and the only draw then it can function as a basic battery monitor because it counts what went in and counts what comes out. No need for a dedicated battery such as the BMV.
If the systems consists of an inverter/charger, MPPTs and a Venus-device, then there is still no need to add a dedicated battery monitor.
For any other system types, such as a boat or vehicle with DC lights and other loads, a dedicated battery monitor will be required.
(A) Battery and Multi or Quattro (a typical backup system)
No battery monitor is required: the Multi or Quattro is the only product connected to the battery and has full control over all charge and discharge currents. Therefore it can calculate the correct SOC itself.
(B) Battery with Multi or Quattro and MPPT Solar Chargers -ALSO- An EasySolar with CCGX built-in
No battery monitor is required, as long as all MPPT Solar Chargers are Victron products and are connected to the CCGX. The CCGX will continuously read the actual charge current from all solar chargers, and send the total to the Multi (or Quattro) which then uses that information in its SOC calculations.
Note that this feature requires recent firmware versions in both the Multis or Quattros (402 minimum), and the CCGX (v2.06 minimum).
(C) Batteries with a built-in battery monitor
In cases where the system includes a battery which has a built-in battery monitor and SOC calculation - such as many of the batteries listed here - a dedicated battery monitor is not required.
Note that the Battery Monitor setting in VEConfigure3 is irrelevant. For systems like this, changing this setting will have no effect on the charge or any other parameters in this type of system.
(D) Other system types
When there are more chargers, or loads, connected to the battery than just the Multi or MPPT Solar Chargers, a dedicated Battery Monitor will be required. Examples are:
Note that the Battery Monitor setting in VEConfigure3 is irrelevant. For systems like this, changing this setting will have no effect on the charge - or any other parameters - in this type of system.
(Settings → System Setup → Battery monitor)
In the image below you can see a range of selectable choices for the SOC values which are shown in the main Overview screen. Choose the source you want to see on the main Overview screen of your CCGX.
In the image above we have chosen the Automatic setting. When automatic is selected the System setup screen will be as shown in the image below.
The 'Automatic' function uses the following logic:
When should I use the 'No battery monitor' option?:
Use that in systems where:
A short explanation: the VE.Bus SOC as determined by the Multi or Quattro will be incorrect in above situation. As it will not take the discharge and charge currents by those other DC Loads, and also unmonitored chargers, into account.
It is possible to use a custom logo onto the Boat & Motorhome page.
Type the following address into the web browser of a device connected to the same network. Using this address as a template: http://[ip-here]/logo.php (inserting your device’s IP address between the square brackets). The IP address can be found by going to Settings > Ethernet or Wifi. Once the page is loaded, Choose an image file from your device. Re-boot the VENUS device.
With DVCC enabled, the Venus-device takes a more central role in the Victron system, improving and changing system behaviour. DVCC allows you to set a maximum charge current setting that applies to the whole system.
For example, an Off-grid system with MPPTs, Multis and a diesel generator. The MPPTs are sized and configured such that they charge the battery with the maximum allowed charge current. If the genset starts while there are no AC loads, with DVCC enabled, the Multi will be limited and prioritise the MPPTs. Without DVCC, the Multi would also start charging with its maximum configured charge current.
This system is also used to apply the various charge and discharge current limits for various CAN-bus BMS connected batteries.
Enabling and disabling DVCC:
Required minimum firmware versions:
In case of an ESS System, the ESS Assistant needs to be version 164 or later (Released in November 2017).
In case of installing a MultiGrid 48/3000 the firmware needs to be version 424 or later.
Do not use DVCC in cases where these requirements are not met.
Important: Where batteries are connected via CAN-bus, check the relevant page on the Battery Compatibility manual to see if enabling DVCC has been tested with your battery-type, and is OK. If DVCC is not mentioned in notes relating to your battery, do not enable DVCC.
For Gel, AGM, OPzS and other lead batteries, DVCC can be used without any problem. The same is true for Victron Energy lithium batteries with the VE.Bus BMS, the Lynx Ion + Shunt BMS or the Lynx Ion BMS. DVCC is the preferred operating mode for Redflow ZBM2/ZCell batteries using the Redflow CANBus BMS.
Below features apply to all types of systems when DVCC is enabled: Offgrid, Backup, ESS, marine and others. And applies to all types of batteries: lead batteries as well as lithium batteries, both with and without a CAN-bus BMS connected to the Victron system.
These features apply to all types of systems (ESS and not ESS), that have a CAN-bus BMS connected battery.

Optimized (with BatteryLife). The system will automatically recharge the battery (from the grid) when the SOC drops 5% or more below the value of ‘Minimum SOC’ in the ESS menu. Recharge stops when it reaches the Minimum SOC.
Sustainmodes were added. In addition it also shows reasons for the state it is in:
