Isolation Because the Cerbo GX 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. • • • • The VE.Bus ports are isolated The VE.Direct ports are isolated The VE.Can ports are not isolated. The USB ports are not isolated.
Cerbo GX Manual • • • • • Only the system connected to the built-in VE.Bus ports is used to generate the data on the Overview pages. All connected systems will be visible on the Device-list All connected systems will be taken into account for Energy consumption and distribution calculations (kWh graphs on VRM) Only the system connected to the built-in VE.Bus ports is used for the Generator start/stop logic In case of an ESS system, only the system connected to the built-in VE.
Cerbo GX Manual VE.Can is intended to be used for the Victron (and Victron compatible) VE.Can products, such as the VE.Can MPPTs, and VE.Can Lynx Shunt. You can string these VE.Can 250 kbit/s devices together along this bus. It must be terminated at both ends with the included VE.Can terminators. BMS-Can is intended to be used with compatible managed battery systems, such as Pylontech, BYD, Freedomwon and many more.
Cerbo GX Manual Type Zero feed-in Details Energy Meter No Wired to the Cerbo GX, or connected wirelessly using our Zigbee to USB/RS485 interfaces. See the Energy Meters start page Wireless AC sensors No See the Wireless AC Sensor manual - Discontinued 2.5. Connecting a USB GPS 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.
Cerbo GX Manual To physically attach the tank probes requires a ferrule or exposed copper end of at least 10 mm+ to be inserted into the removable terminal block connector. Once correctly attached, you must use the orange tab if you wish to remove the secured wire. 2.8.
Cerbo GX Manual 2.9. Connecting Temperature Sensors See the Connection Overview [2] for the location and number of temperature sensors. They can be used to measure & monitor all kinds of temperature-inputs. Temperature senders are not included. The required sensor is ASS000001000 - Temperature Sensor QUA/PMP/Venus GX. (Note that this is different to the BMV temperature accessory.) They are not required to be connected to the battery (though they appear like a battery lug).
Cerbo GX Manual The IMT Si-RS485 series solar irradiance sensors operate using RS485 electrical interface and Modbus RTU communication protocol. The required interface software is pre-installed within the Venus OS, however the Victron GX device must be running recent firmware - FW v2.40 is the minimum requirement. Physical connection to the Victron GX device is via USB port and requires a Victron RS485 to USB interface cable.
Cerbo GX Manual For 12 V battery banks/systems the IMT Si-RS485 series solar irradiance sensor range may be powered directly from the battery bank and will continue to operate down to minimum voltage of 10.5 V (as measured at the sensor, account for voltage drop in the cable). For detailed wiring/installation notes and specifications refer to the IMT Si-RS485 series solar irradiance sensor 'Quick Reference Guide' and Victron RS485 to USB interface cable ‘Datasheet’.
Cerbo GX Manual Within the ‘IMT Si-RS485 Series Solar Irradiance Sensor’ menu all available parameters will be automatically displayed (dependent on the sensors connected) and update in real time. Within the ‘Settings’ sub-menu it is possible to manually enable and disable any optional/additional external sensors that are connected to the IMT Si-RS485 Series irradiance sensor.
Cerbo GX Manual 2.10.1. Data Visualisation - VRM To review logged historical data on the VRM portal, expand the ‘Meteorological Sensor’ widget list and select the ‘Meteorological Sensor’ widget. Data from all available sensor types will be automatically displayed in the graph. Individual sensors/parameters can also be disabled/enabled by clicking on the sensor name/legend.

Cerbo GX Manual 4. Accessing the GX device It is possible to access the GX device using either a smartphone, tablet or computer. This access is called Remote Console. In GX devices with a display this Remote Console feature may be disabled by default and need to be enabled. GX devices without a display have Remote Console enabled by default.
Cerbo GX Manual Make sure that the Cerbo GX is powered on, and the Bluetooth LED is blinking. Open the VictronConnect App within 10 meters of the Cerbo GX and wait for nearby devices to be discovered. Once discovered, Click or Tap on the Cerbo GX. On first connection you will be asked to enter a bluetooth PIN code - the default PIN is 000000 You will then be asked to change this insecure default PIN code to a more secure unique code.
Cerbo GX Manual From the main device screen it is possible to change the networking settings, view the system on VRM, or open the Remote Console. Network settings for the Cerbo GX are set in the Cog menu.
Cerbo GX Manual Note - Bluetooth functionality is limited to the features mentioned above. It is intended to be used to assist with initial connection and networking configuration. You cannot use Bluetooth to connect to other Victron products (e.g. SmartSolar charge controllers). For more information about how to connect other Victron products, please see Connecting Victron products [3] 4.2.
Cerbo GX Manual IP Address on VRM On the VRM Portal, you'll find the IP address on the Device List page of the installation. Note that this does require the Cerbo GX to be connected to the internet. Network (on Microsoft Windows) In a local network, for example at home, you can also find the Cerbo GX in the Windows 'Network' overview: Double-clicking the icon will open up Remote Console on LAN.
Cerbo GX Manual Open the 'Properties' window to see the IP address.
Cerbo GX Manual This uses Universal plug-and-play broadcast technology. 4.4. Accessing via VRM This method requires a working internet connection, both on your phone/tablet/laptop as well as for the Cerbo GX. For a new install, this means that it needs to be connected by Ethernet cable. Step by step instructions: First, connect the Cerbo GX to the internet by plugging it into a working Ethernet network which has a DHCP server, as most networks do, and which is connected to the internet.

Cerbo GX Manual Item Default Description MQTT on LAN (SSL) On Enables MQTT on LAN - More information on MQTT is available on Victron Community. MQTT on LAN (Plaintext) Off This setting is required to be enabled when connecting an Marine MFD VE.Can port VE.Can CAN-bus profile (Disabled, VE.Can & Lynx Ion BMS 250 kbit/s, VE.Can & Can-bus BMS 250 kbit/s, CAN-bus BMS 500 kbit/s, Oceanvolt 250 kbit/s), Send data to VE.Can, Unique device number for VE.
Cerbo GX Manual No battery monitor is required, as long as all MPPT Solar Chargers are Victron products and are connected to the Cerbo GX . The Cerbo GX 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. Configuration: 1. Enable and configure the Battery Monitor in VEConfigure. 2. On the Cerbo GX , in Settings → System setup, verify the selected Battery Monitor.
Cerbo GX Manual 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: 1. When available, it will use a dedicated Battery Monitor, such as the BMV or a Lynx Shunt, or a battery with built-in battery monitor. 2. When there is more than one of those connected, it will use a random one - although you can select one manually. 3.
Cerbo GX Manual 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. 5.2.5. Details on VE.Bus SOC • While the Inverter/Charger is in bulk, the SOC will not rise above the value as set in VEConfigure3 for the “State of charge when Bulk finished“ parameter on the General tab; default 85%.
Cerbo GX Manual 6. GX - How to update firmware 6.1. Changelog The change log is available in Victron Professional, under Firmware, Venus OS. 6.2. Via internet or with microSD-card/USB-stick There are two ways to update the firmware: 1. Update it via the internet, either manually or let it check for new updates every day 2. Update it from a microSD-card or USB-stick 6.3.
Cerbo GX Manual Step 4. Initiate the update Navigate to Settings → Firmware → Offline updates. Press Check for updates If the firmware in the microSD-card or USB-stick is newer than the running one, “Update available” item will appear, press it to start the update process.
Cerbo GX Manual 7. VE.Bus Inverter/charger monitoring 7.1. Input current-limiter setting 'Overruled by remote' setting in VEConfigure 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 Cerbo GX will be applied to all inputs where 'Overruled by remote', configured with VictronConnect or VEConfigure, is enabled: Using the example of a boat with two AC inputs and a Quattro where: 1.
Cerbo GX Manual Minimum input current limit values 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).
Cerbo GX Manual And also it will be listed in the Alarm Log on VRM, and an email will be sent; using the VRM Alarm Monitoring system. 7.3. Grid failure monitoring When this feature is enabled, an alarm is raised when the system hasn't been connected to the AC input configured to be Grid or Shore for more than 5 seconds. The alarm shows as a Notification in the GUI, and as an alarm on the VRM Portal, and is available on ModbusTCP / MQTT. Recommend to use for backup systems.
Cerbo GX Manual System reset Restarts the inverter/charger when it has stopped retrying. For example after a (very) heavy overload; or three overloads in a row. ESS Relay test Shows the status of the ESS Relay test. Only relevant when its an ESS system. See Q9 in the ESS Manual FAQ for details Page 41 VE.
Cerbo GX Manual 8. DVCC - Distributed Voltage and Current Control 8.1. Introduction and features Enabling DVCC changes a GX device from a passive monitor into an active controller. The available features and effects of enabling DVCC depend on the type of battery used. The effect also depends on the installed Victron components and their configuration.
Cerbo GX Manual 8.2. DVCC Requirements Battery compatilibity For CAN-bus connected batteries, check the relevant page on the Battery Compatibility manual to see if enabling DVCC has been tested with your battery-type and is supported. 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.
Cerbo GX Manual MPPT indicated charge state: Ext. control. Battery The internal charge algorithm is disabled; and instead, the device is being controlled by the battery. Inverter/charger indicated charge state: Bulk when in current controlled mode, Absorption when in voltage controlled mode. Never Float; even though currents might be low / battery might be full. MPPT indicated charge state: Ext. control. 8.4.
Cerbo GX Manual 8.4.3. Shared Temperature Sense (STS) Select the temperature sensor to use; and the GX device will send the measured battery temperature to the Inverter/charger system as well as all connected Solar Chargers. Selectable sources for the battery temperature are: • • • • • • BMV-702 battery monitor BMV-712 battery monitor Lynx Shunt VE.
Cerbo GX Manual 8.6. DVCC for systems with the ESS Assistant • The ESS Keep batteries charged mode works properly. It does not without DVCC. • A fixed solar offset of 0.4V is used instead of a variable 2V. (values for 48V systems, divide by 4 for 12V). Note that this solar offset is only applied when ESS-mode is set to Optimized in combination with the Feed-in excess solar charger power-setting enabled, or when ESS-mode is set to Keep batteries charged.
Cerbo GX Manual 9. VRM Portal 9.1. VRM Portal Introduction When connected to the internet, a GX device can be used in combination with the Victron Remote Management (VRM) portal, which enables: • • • • Easy remote access to all statistics and systems status online Remote Console on VRM: access and configure your system as if you were standing besides it Remote Firmware updates of connected Solar Chargers and other Victron products. Use of the VRM App for iOS and Android.
Cerbo GX Manual Manually transferring datalogs to VRM For devices permanently without Internet, it is possible to take the data out, and then upload it manually from a laptop. 1. go to Settings → VRM Portal, and click Eject the storage. Make sure to never just remove the SD-card/USB-stick, this can lead to corruption and data loss. 2. now, remove the storage device and insert it into a computer or laptop that is connected to the internet. 3. open a webbrowser, and navigate to the VRM Portal. 4.
Cerbo GX Manual 1. 2. 3. 4. State must be ‘Connected’ There must be an IP address, that does not start with 169. There must be a gateway There must be DNS servers For a GX GSM, see the Troubleshooting guide in the GX GSM Menu. In case the IP address starts with 169, check whether your network has a DHCP server running. 99% of all networks have a DHCP server running and it is enabled by default on all well-known ADSL, cable and 3G routers.
Cerbo GX Manual • Error #150 Unexpected response text: The http/https call succeeded, but the response was incorrect. This indicates that there is a WiFi or network login page. Such as seen in Airports, Hotels, Marinas or RV campgrounds some times. There is no solution to make the CCGX work with a WiFi network that requires such login page and/or accepting of terms of use.
Cerbo GX Manual Check 'Last contact'. If this shows dashes, the GX device has not been able to contact the VRM Portal since power up. If it shows a time, but still an error is shown, then the GX device has been able to send data, but has since lost contact. The 'Buffered items' indicates the number of logs that it has stored to send later. If this is larger than 0, it means that the Cerbo GX can not connect to the VRM Portal.
Cerbo GX Manual When using Remote Console on VRM, the browser will connect to either vncrelay.victronenergy.com, or vncrelay2.victronenergy.com, using websockets on port 443. For more details of used connections by the GX Device, see Q15 of the FAQ.
Cerbo GX Manual 10. Marine MFD integration by App 10.1. Introduction & requirements A Glass Bridge is a MFD (Multi-Functional Display) that integrates a boat’s systems and navigation status into a large screen or screens at the helm of the vessel, so doing away with multiple gauges, brackets and wiring complications. A Victron system can be easily integrated into that, as shown in this video: https://www.youtube.com/watch?v=RWdEQfYZKEs Functionalities: • Monitor shore power and generator status.
Cerbo GX Manual • • • • • • Battery system. Victron GX Device (all models are compatible: CCGX, Cerbo GX, Venus GX, and so forth) Victron Inverter/charger. Victron Battery monitor. Ethernet network cable connected between MFD and the GX device MFD specific ethernet adapter cable (only for some brands, see detailed information in below links) 10.2.
Cerbo GX Manual 11. Marine MFD integration by NMEA2000 11.1. NMEA2000 Introduction Our GX Devices feature an NMEA 2000-out function: when enabled, the GX Device acts as a bridge: it makes all Battery monitors, Inverter/chargers and other products connected to the GX device available on the NMEA2000 network. Using that feature, and having the GX Device connected a NMEA2000 network, Marine MFDs can read this data and visualise it to the user. Often in a highly configurable manner. Use our VE.
Cerbo GX Manual Displays not being capable of doing so will regard the data as belonging to the mains (utility). The Inverter Output is then interpreted as utility #0 and Inverter Input as utility #1. These default instance numbers can be changed by a network configuration tool if necessary. Battery temperature as measured by the inverter(/charger) is transmitted as well. All VREG communications need to be sent to be sent to the address representing the Inverter function.
Cerbo GX Manual Table 1. Setting Default Description CAN-bus Profile VE.Can Defines the type & baudrate of the CAN-bus network. To use in combination with NMEA2000, make sure to choose one of the profiles that include VE.Can and is at 250kbit/s NMEA2000-out Off Enables and disabled the NMEA2000-out function Unique identity number selector 1 Selects the block of numbers to use for the NAME Unique Identity Numbers in the PGN 60928 NAME field.
Cerbo GX Manual 11.5. NMEA2000-out technical details 11.5.1. NMEA2000 Glossary Here is a glossary to help with the interpretation of this text: • Virtual-device: a Battery Monitor, Inverter, or other Victron device that does not have a CAN-bus port by itself, made available “virtually” on the CAN-bus by the NMEA2000-out function of the GX Device. • CAN-bus: the VE.Can port on the GX Device, that, in the context of this chapter, is most likely connected to a NMEA2000 network.
Cerbo GX Manual Address Class Function Description 0xE4 35 (Electrical generation) 170 (Battery) The 2nd BMV 0xD3 35 (Electrical generation) 153 The inverter/charger (AC-output) 0xD6 35 (Electrical generation) 154 The inverter/charger (AC-input) 11.5.3. NMEA2000 Classes and functions As per NMEA2000 specification, these define the types of senders and devices connected to the CAN-bus. Classes are the main categories, and functions specify it to a further detail. 11.5.4.
Cerbo GX Manual • Device Instance Upper Here is how they all relate: the ECU Instance and Function Instance terminology originates from the SAE J1939 and ISO 11783-5 specification. And they do not exist in the NMEA2000 definition. However, they all do define the same fields in the same CAN-bus messages which NMEA2000 defines as Device instance. In more detail: the field that J1939 defines as ECU Instance is in the NMEA2000 specification renamed to Device Instance lower.
Cerbo GX Manual 12. Digital Inputs The Cerbo GX digital inputs are shown in the overview of connections. [2] 12.1. Configuration Each of the digital inputs can be configured as one of a number of predefined sensors that can also be configured as alarms. Note Pulse Meter is not supported in Cerbo GX.
Cerbo GX Manual Other parameters related to that function can be configured by entering the device menu and selecting Setup. For sensors and alarms, you can decide whether the input should be treated as an alarm condition, whether the labels should be inverted, and whether the logical levels should be inverted. • To swap the labels attached to the alarm, set Inverted to on. • If a logical low input (0V) should be considered a positive condition, set Inverted alarm logic to on. 12.2.
Cerbo GX Manual 13. GX - Generator auto start/stop 13.1. GX - Generator auto start/stop Introduction An internal relay on a GX device (eg Cerbo GX/Cerbo GX) can be used to automatically start and stop a generator. This relay - or switch - can be 'tripped' by a number of user-defined conditions. This manual will explain what conditions are available to you; and it will guide you through the steps required to set-up this useful functionality.
Cerbo GX Manual 13.4. General start/stop - Main Page From the Main Menu select Settings > Generator start/stop: • • • • • • • Generator state: Current status of the generator. Error: Error description. Runtime: Generator run-time since last start. Total run time: Accumulated running time since the first start. Time to next test run: When the 'test run' option is enabled this item shows the time remaining until the next test run. Daily runtime: Running time history for the last 30 days.
Cerbo GX Manual * Battery monitor: Select how the battery will be monitored - if at all. The battery monitor data will be used for DC-related conditions. * On loss of communication: If ever there is a communication breakdown between the Cerbo GX/Cerbo GX and the selected battery monitor, and/or VE. Bus inverter/charger; and parameters have been set which depend on this information - choose between the following actions: • Stop the generator: If the generator is running, it will be stopped.
Cerbo GX Manual • Start after condition is reached for: Set a delay before auto-start. Some AC device will draw a short-term, high-peak current on start-up. Instigating a delay before auto-start will avoid starting the generator unnecessarily. • Stop when battery current is lower than: Set the current for auto-stop. • Stop value during quiet hours: If Quiet hours has been defined, set a higher current level to achieve shorter generator runtimes.
Cerbo GX Manual Automatic periodic 'Test run' This feature allows automatic generator starts, periodically, as a 'test run'. • Test run interval: Set the interval between test runs. • Skip test run if has been running for: The test will be skipped if during the test run interval the generator ran for at least as long as it would on a 'test run'. • Test interval start date: The 'test run' interval counter will start from the date entered here.
Cerbo GX Manual Quiet hours Quiet hours allows you to define a period during which the noise from a running generator would be a nuisance; and to set different values to the conditions which would cause an auto-start during this period - thus ensuring that the generator will only start during a quiet period when it is absolutely necessary. From the main menu go to: Settings → Generator start/stop → Settings; and then toggle-on the Quiet hours feature.
Cerbo GX Manual 14. Error Codes Different origins of errors On your GX device, some error codes shown will be from the GX device itself, in that case see below list. As the system control panel, it also shows error codes from the connected devices. • Multi and Quattro inverter/chargers: VE.Bus Error Codes • MPPT Solar Chargers: MPPT Solar Charger Error Codes GX Error #42 - Storage corrupt This error means that the flash memory inside the GX Device is corrupt.
Cerbo GX Manual 15. FAQ 15.1. 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 Cerbo GX. In most systems they will be connected directly to the VE.Bus port on the back of the Cerbo GX. And, option two, in some systems they are connected to the Cerbo GX using a VE.Bus to VE.Can interface.
Cerbo GX Manual • 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? The general answer is: the Multi and Quattros are not measurement instruments, they are inverter/chargers, and the measurements shown are a best effort delivery. In more detail, there are several causes for measurement inaccuracies: 1.
Cerbo GX Manual 15.11. Q11: How long should an automatic update take? The size of the download typically is around 90MB. After download it will install the files which can take up to 5 minutes. 15.12. Q12: I have a VGR with IO Extender, how can I replace this with a Cerbo GX? It is not yet possible to replace the IO Extender functionality. 15.13. Q13: Can I use Remote VEConfigure, as I was doing with the VGR2? Yes, see VE Power Setup manual 15.14.
Cerbo GX Manual • Port 22 - see the Venus OS root access documentation. • This is a software developers feature. 15.16. Q16: What is the functionality behind the menu item Remote support (SSH), in the Ethernet menu? When enabled, the Cerbo GX will open a SSH connection to our secure server, with a reverse tunnel back to the Cerbo GX. Through this tunnel, Victron engineers can login to your Cerbo GX and perform remote support. This works when the Cerbo GX is installed on an internet connection.
Cerbo GX Manual The disadvantage of cutting pin 7 is that switching the VE.Bus device off will be less effective: although it will stop charging and inverting, it will still be in standby mode and therefore drawing more current from the battery than if pin 7 had been left in place. Typically this is only relevant in Marine or Automotive systems where it's normal to regularly switch the VE.Bus device off.
Cerbo GX Manual 15.24. Q24: What is Error #42? If the GX Device shows an Error 42 - Hardware fault. In that case, the flash storage on the device is corrupt. As a result, settings will not be saved (rebooting resets back to default) and other problems will rise. This error is not recoverable in the field or by repair departments. Contact your dealer for a replacement. Firmware versions until v2.30 did not report the error. Since v2.30; its visible on the device itself (in the GUI) and on the VRM Portal.
