• 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. Setting the input current limit is possible in systems with a VE.Bus BMS.

• Combining MultiPlus/Quattro with a VE.Bus BMS and a Digital Multi Control is possible. Simply connect the Digital Multi Control

to the RJ-45 socket on the VE.Bus BMS labelled Remote panel.

• To allow auto-power-down in the Cerbo GX in case of a low battery, make sure the Cerbo GX is powered via the VE.Bus BMS:

connect Power in V+ on the Cerbo GX to Load disconnect on the VE.Bus BMS. And connect both negative leads to the nega-

tive stub of a common Battery.

Combining the Cerbo GX with a Digital Multi Control

It is possible to connect both a Cerbo GX and a Digital Multi control to a VE.Bus system. The ability to switch the product On, Off

or set it to Charger Only via the Cerbo GX will be disabled. The same applies to the input current limit: when there is a Digital

Multi Control in the system, the input current limit which is set at that control panel will be the master-setting, and changing it on

the Cerbo GX will not be possible.

Connecting multiple VE.Bus systems to a single Cerbo GX

Only one VE.Bus system can be connected to the VE.Bus ports on the back of the Cerbo GX. The professional way to to monitor

more systems is to add a second Cerbo GX

If you do require to connect more than one system to the same Cerbo GX, use an MK3-USB. Functionality will be limited:

• 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.Bus ports is used in the ESS mechanisms. The other

one is displayed in the device list only.

Alternatively the VE.Bus to VE.Can interface (ASS030520105) can be used. Add one for each additional system. Note that we

advise against it; this interface is a deprecated product. Make sure that the VE.Can network is terminated and powered. For pow-

ering the VE.Can network, see Q17 in our data communication whitepaper.

2.4.2. Battery Monitor BMV-700 series; and MPPTs with a VE.Direct port

Either one or two compatible products can be connected directly to the Cerbo GX using a standard VE.Direct cable. There are

two types of VE.Direct cable available:

1. Straight VE.Direct cables, ASS030530xxx

2. VE.Direct cables with an angled connector on one end. These are designed to minimize the required depth behind a panel,

ASS030531xxx

VE.Direct cables have a maximum length of 10 metres. It is not possible to extend them. If longer lengths are required, use a

VE.Direct to USB adapter with an active USB extension cable.

It is also possible to use the VE.Direct to VE.Can interface, but note that this only works for BMV700 and BMV702. Not for the

BMV712, MPPT solar chargers and Inverters with a VE.Direct port. See next paragraph for more information on that VE.Can in-

terface.

Connecting more than two devices to your Cerbo GX using VE.Direct

First of all, note that the maximum of VE.Direct devices that can be connected, regardless of the interface is limited. How they are

connected, either direct, via USB or via CAN, does not change the maximum. See here for the maximum connected device limits.

Select the correct GX device for the number of connected devices required by the system.

• Option 1: Use the VE.Direct to USB interface. The Cerbo GX has built-in USB ports (see Overview of Connections [5]). Use a

USB-hub when additional USB ports are required.

• Option 2: The BMV700 and BMV702 can also be connected using the VE.Direct to VE.Can interface. Note that the BMV712,

MPPTs and VEDirect Inverters cannot be connected using this canbus interface as it does not translate the data into canbus

messages. When using the VE.Direct to VE.Can interface, make sure that the VE.Can network is terminated, and also pow-

ered. For powering the VE.Can network, see Q17 in our data communication whitepaper.

Notes about older VE.Direct MPPTs

• An MPPT 70/15 needs to be from year/week 1308 or later. Earlier 70/15s are not compatible with the Cerbo GX, and unfortu-

nately upgrading the MPPT firmware will not help. To find the year/week number of your model, look for the serial number

which is printed on a label on its back. For example number HQ1309DER4F means 2013, week 09.

2.4.3. Skylla-i, Lynx Shunt VE.Can, Lynx Ion + Shunt and MPPTs with a VE.Can port

To connect a product with a VE.Can port, use a standard RJ45 UTP cable. (Available with straight and elbow connectors)
