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. The Venus-device ensures that they all work in harmony. Monitoring can be carried out locally …or remotely - via our free-to-use Victron Remote Management portal (VRM). The GX-device also provides Remote firmware updates and even allows the settings to be Changed Remotely.

The GX Family consists of these models:

Color Control GX
Venus GX
The CANvu GX is best for harsh environments - when its IP67 rating 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 - suited for systems having many MPPT Solar Chargers, as it has 25 VE.Direct ports.

Also, there is a GX device built into our MultiPlus-II GX and EasySolar-II GX Inverter/chargers. There, its referred to as the GX Card.

Available accessories

GX GSM - A cellular modem. It connects to Venus-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 Venus-device.

Notes

The maximum number of VE.Direct devices which can be attached to a CCGX is 5 (2 direct, and 3 via USB); on a Venus GX the number is 6 (2 direct and 4 via USB); on an Octo GX it is 10 (all attached directly). VE.Direct ports on a Venus-device are isolated.
Though the CCGX has no built-in WiFi that functionality can easily be added by attaching a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details.
The built-in WiFi in the Venus GX has a very low signal strength - unfortunately. It is strong enough to connect to a phone, tablet or laptop in order to access setup and monitoring. But to connect the Venus GX to the internet either use the built-in Ethernet port or add a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details. Make sure the Venus GX is running v2.06 or later - early shipments of Venus GX units ran v2.05.
The hardware of the Venus GX and Octo GX includes a built-in Bluetooth Smart chipset which hasn't proved satisfactory. Bluetooth Smart for Venus-devices is coming soon but will not use built-in chipsets.
Larger SD memory cards (SDXC) are not supported. SD cards can be used for two purposes:
1. Logging data, see this section in the ccgx manual for details.
2. Updating firmware, see this section in the ccgx manual for detials.
The second CANbus port is accessible via the GND, CAN-H and CAN-L terminals. Note that the port is not Isolated. See Settings → Services for configuring that port.
The programmable relay can be set to act as an alarm relay, automatic genset start stop, or an on/off switch, and is controlled via the GUI and/or ModbusTCP.
In the Venus GX hardware there are two relays - at present only one of them is available for use.
The tank level inputs are resistive and should be connected to a resistive tank sender. Victron does not supply tank senders. The tank level ports can each be configured to work with either European (0 - 180 Ohm); or US tank senders (240 - 30 Ohm).
The Venus GX has two temperature terminals which 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 not the same as the BMV temperature accessory.)
Octo GX comes with a small Wifi antenna. You may remove and replace it with any other Wifi antenna having an RP-SMA connector.
Requires the CANvu GX IO Extender and wiring kit
