Victron GX product range
Introduction
GX products are Victron's state-of-the-art monitoring solution. The family consists of the different GX
products, and their accessories.
The GX-device lies at the heart of the system - providing monitoring, and operating as the
communication-centre of your installation. All the other system-components - such as
inverter/chargers, solar chargers, and batteries - are connected to it. Monitoring can be carried out
locally and remotely - via our free-to-use Victron Remote Management portal (VRM). The GX-device
also provides Remote firmware updates and allows inverter/charger settings to be changed remotely.
The GX Family consists of these models:
Cerbo GX - Our newly released GX product.
Color Control GX - Our first released GX product, the CCGX has a display and buttons.
Venus GX - The Venus GX has more analog and digital IO, no LCD and is more cost effective
than the CCGX.
CANvu GX - The CANvu GX is best for harsh environments - when its IP67 rating and touch LCD
is a must.
Octo GX - The Octo GX is particularly suited to medium size installations which have many MPPT
Solar Chargers, as it has 10 VE.Direct ports.
Maxi GX - Compared to the other GX devices, the Maxi GX has most CPU power and most
VE.Direct ports: 25. This is the GX device to use for large systems with many VE.Direct MPPT
Solar Chargers.
Lastly, there is a GX device built into our MultiPlus-II GX and EasySolar-II GX Inverter/chargers.
Available accessories
GX Touch 50 - Touch screen display accessory for the Cerbo GX
GX GSM - A 2G and 3G cellular modem. It connects to GX device via USB, and takes a simcard
GX LTE 4G - A 2G, 3G and 4G cellular modem. It connects to GX device via USB and takes a
simcard
WiFi USB sticks
Energy Meters - Measures PV Inverter Output where PV Inverters cannot be read-out directly.
Also used as a grid meter in an Energy Storage System (ESS).
VE.Can resistive tank sender adapter Allows a standard resistive tank-level sender to be
connected to the GX device.

Notes
The listed maximum on the `Performance` section in above table is the total connected1.
VE.Direct devices such as MPPT Solar Charge controllers. Total means all directly connected
devices plus the devices connected over USB. The limit is mostly bound by CPU processing
power. Note that there is also a limit to the other type of devices of which often multiple are
connected: PV Inverters. Up to three or four three phase inverters can typically be monitored on
a CCGX. Higher power CPU devices can monitor more.

later - early shipments of Venus GX units ran v2.05.

Systems and others, at 500kbps. The hardware does not meet the requirements for a VE.Can
port; and thus it is not possible to use to port to connect Victron products such as the
SmartSolar VE.Can MPPT product range. Note that for a while Venus OS firmware did allow to
select the VE.Can function and other baudrates. The result will be unreliable, and therefor they
have been updated to lock into BMS-Can only at 500kbps.

to connect Victron VE.Can products to that port. To connect such managed battery, use our
special cables, and see documentation here. Connect the side labelled 'VE.Can' into the BMS-
Can/VE.Can port on the GX Device. And connect the other side to the battery. The baudrate of a

cables, USB-sticks, USB-GPS-es, or other common USB usages. It’s a power port only, no data.
Future versions of Venus OS will disable all data related features of this port, so it should not be
used for anything other than powering the GX Touch screen. Attempting to use this port for
data purposes may lead to corrupted VRM data on USB sticks or unreliable communication to
for example a Solar Charger when using a VE.Direct to USB cable.
