Cerbo GX Manual 1. Introduction 1.1. What is the Cerbo GX? The Cerbo GX 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 Cerbo GX ensures that they all work in harmony. There is an optional touch screen accessory for the Cerbo GX called the GX Touch.
Cerbo GX Manual 2. Installation 2.1. Overview of connections VE.Direct inverter, charger, peak power pack Networking Modbus TCP, Internet connectivity VRM & Remote Support Internet router GX Touch 50 touchscreen display RS inverter Skylla-i, Skylla-S charger VE.Can RS485 Energy meter, IMT solar irradiation, wind and temperature sensor BMV & SmartShunt Compatible AC PV inverter HDMI USB Compatible Marine MFD 3 x VE.
Cerbo GX Manual • The VE.Direct ports are isolated • The VE.Can ports are not isolated. • The USB ports are not isolated. Connecting a Wi-Fi Dongle or GPS Dongle will not create a problem as it is not connected to another power supply. Even though there will be ground loop when you mount a separately-powered USB hub, during extensive testing we have not found that it caused any issues.
Cerbo GX Manual It is possible to mount the GX Touch in several different ways, using the included bracket frames.
Cerbo GX Manual 2.4. Connecting Victron products 2.4.1. Multis/Quattros/Inverters (VE.Bus products) 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 Cerbo GX 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.
Cerbo GX Manual • Connect the Cerbo GX to the socket labelled ‘MultiPlus/Quattro’, or to one of the Multis/Quattros in the system. Do not connect it to the Remote panel socket on the VE.Bus BMS. • Note that it will not be possible to control the On/Off/Charger Only switch. This option is automatically disabled in the Cerbo GX menu when a VE.Bus BMS is used. The only way to control a Multi or Quattro when used with a VE.Bus BMS is to add a Digital Multi Control to the system.
Cerbo GX Manual Don't forget to terminate the VE.Can network at both ends using a VE.Can terminator. A bag with two terminators is supplied with each VE.Can product. They are also available separately. Other notes: 1. 2. 3. 4. In order to work with the Cerbo GX an MPPT 150/70 needs run firmware v2.00 or newer. You can combine a Skylla-i control panel with a Cerbo GX. You can combine a Ion Control panel with a Cerbo GX. The Skylla-i, Lynx Shunt VE.Can, Lynx Ion + Shunt and the MPPTs with a VE.
Cerbo GX Manual Type Zero feedin Details AC Current Sensor No Connected to inverter/charger analog input. Lowest cost - least accurate. Energy Meter 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 2.7.
Cerbo GX Manual It is also possible to connect an independent IMT Tm-RS485-MB module temperature sensor (visible as ‘cell temperature’) or IMT Ta-ext-RS485-MB ambient temperature sensor (visible as ‘external temperature’) directly to the Victron GX device, without a solar irradiance sensor or in addition to one. Operation The IMT Si-RS485 series solar irradiance sensors operate using RS485 electrical interface and Modbus RTU communication protocol.
Cerbo GX Manual The maximum DC power supply voltage permitted for the IMT Si-RS485 series solar irradiance sensor range is 28.0 VDC - accordingly for 24 V and 48 V battery banks/systems an appropriate Victron DC-DC converter (24/12, 24/24, 48/12 or 48/24) or ACDC adaptor must be utilised in the installation. 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.
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.
Cerbo GX Manual Data from all available sensor types will be automatically displayed in the graph.

Cerbo GX Manual Note that this feature requires recent firmware versions in both the Multis or Quattros (402 minimum), and the Cerbo GX (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. Configuration: 1. Connect the battery communications cable to the Cerbo GX according to the instructions. 2.
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 3. the system has other DC loads, or other chargers, connected to the same battery, which are not connected to the Cerbo GX. 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.

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 Systems where it is not possible to control the input current limit It is not possible to control the input current limit in certain installations. In these cases, the Cerbo GX menu will not allow changing the setting: 1. Installations with a VE.Bus BMS 2. Installations with a Digital Multi Control (or its predecessors) Also the on/off/charger only switch in the Cerbo GX will be disabled in the case. In installations with a VE.
Cerbo GX Manual And on the VRM Portal, it is visible on the VE.Bus Alarms & warnings widget on the Advanced page: 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.
Cerbo GX Manual 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. But also for yachts or vehicles on shore power. Note that this settings monitors that the system is connected to grid/shore. Generator monitoring is already available as part of the Generator start/stop function and not part of this.
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 The MPPTs internal charge algorithm is disabled; instead it's being controlled by a charge voltage setpoint coming from the inverter/charger. 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.
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 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 2. There must be an IP address, that does not start with 169. 3. There must be a gateway 4. 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. If there is no DHCP server running, then configure the ip address manually.
Cerbo GX Manual If a Connection error is shown, the Cerbo GX is not able to contact the VRM database. The connection error will show an error code that indicates the nature of the connectivity problem. Also, details of the error message are shown, to facilitate on site IT experts to diagnose the problem. • Error #150 Unexpected response text: A connection succeeded, but the result was incorrect. This might indicate that a transparent proxy is hijacking the connection.
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 inverter/charger. Victron Battery monitor. Network cable connection between MFD and GX device (directly, or via network router) UTP network cable. 10.2. Compatible MFDs and instructions Instructions for Garmin MFDs Instructions for Navico MFDs (Simrad, B&D, Lowrance) Instructions for Raymarine Furuno: support on Furuno MFDs is in the pipeline. There is no expected date of availability.
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 je 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 Only VE.Bus type inverters are supported: any Inverter connected using VE.Direct is not (yet) made available on the N2K bus. Battery monitors Supported. This includes any battery monitor as supported by the GX Device. Other data and product types Not supported. Above are the only now supported types. For example tank levels are not yet transmitted out on N2K, nor is any data from a charger (such as the Phoenix Smart Charger connected via VE.Direct), and neither is data from solar chargers.
Cerbo GX Manual 1. 0xFD (253) - Reserved 2. 0xFE (254) - Unable to claim address - for example when all others are in use 3. 0xFF (255) - The broadcast address 11.4.1. NMEA2000 Glossary 11.4.2. NMEA2000 Virtual-devices35 (Electrical generation) When the NMEA2000-out feature is enabled, the GX Device acts as a bridge: it will make each Battery monitor, Inverter/charger or other device that is connected, available individually on the CAN-bus.
Cerbo GX Manual The ECU instance and Function instance In some documentation and software tools, yet other terminology is used: • • • • ECU Instance Function Instance Device Instance Lower 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.
Cerbo GX Manual 12. Digital Inputs The Cerbo GX digital inputs are shown in the overview of connections. [5] 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. 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 14. FAQ 14.1. Cerbo GX FAQ 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 In more detail, there are several causes for measurement inaccuracies: 1. Part of the power taken from a battery by the inverter is being lost in the inverter, converted into heat: efficiency losses. 2. The Multi does not really measure the power being drawn from the battery. It measures the current at the output of the inverter, and then makes an assumption of the power being drawn from the battery. 3.
Cerbo GX Manual 14.14. Q14: The Blue Power Panel could be powered through the VE.Net network, can I also do that with a Cerbo GX? No, a Cerbo GX always needs to be powered itself. 14.15. Q15: What type of networking is used by the Cerbo GX (TCP and UDP ports)? Basics: • The Cerbo GX needs to get a valid IP address from a DHCP server, including a working DNS server and gateway, or a static IP configuration.
Cerbo GX Manual 14.18. Q18: What is the data usage of the Cerbo GX? Data usage depends heavily on amount of connected products, and behavior and usage of those products. The measurements below are an indication only, and taken from a system with one Cerbo GX, one Multi, one BMV and one MPPT. Log interval set to 15 minutes. If you are on an expensive data-plan, do make some fail-safe.
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 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. 14.25.
