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. In order to work with the Cerbo GX an MPPT 150/70 needs run firmware v2.00 or newer.
2. You can combine a Skylla-i control panel with a Cerbo GX.
3. You can combine a Ion Control panel with a Cerbo GX.
4. The Skylla-i, Lynx Shunt VE.Can, Lynx Ion + Shunt and the MPPTs with a VE.Can port all power the VE.Can network …so it
won't be necessary to power the VE.Can network separately in these circumstances. All the protocol converters - for example
the VE.Bus to VE.Can interface; and the BMV to VE.Can interface, do not power the VE.Can network.
2.4.4. BMV-600 series
Connect the BMV-600 using the VE.Direct to BMV-60xS cable. (ASS0305322xx)
2.4.5. DC Link box
Connect the DC Link box, using the RJ-12 cable supplied. Then connect the BMV-700 to the Cerbo GX - see connecting
BMV-700 for more instructions.
2.4.6. VE.Can Resistive Tank Sender Adapter
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.
2.5. NMEA Tank senders from other manufacturers
A tank sender must meet the following requirements to be visible on the Cerbo GX:
• Transmit the NMEA2000 Fluid Level PGN, 127505
• The NMEA2000 device class needs to be 'General', 80
• The NMEA2000 function needs to be 'Transducer', 190
Since v2.17 the following functions are accepted as well:
• The NMEA2000 device class 'General', 80 and function 'Sensor', 170
• The NMEA2000 device class 'Sensors', 75 and function 'Fluid Level', 150
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 Cerbo GX - for example the Mare-
tron 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 Cerbo GX, 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-adap-
tor/. 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.
2.6. Connecting a PV Inverter
Measuring the output of a PV Inverter will provide the user with an overview of both actual power balance and the energy distribu-
tion. Note that these measurements are only used to display information. They are not needed, nor used, by the installation for its
performance. Besides monitoring, the GX device can also curtail some types and brands of PV Inverters, ie. reduce their output
power. This is used, and required, for the ESS Zero feed-in feature.
