Manual

• 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
• The CCGX will not send proper data to VRM any more. The Venus GX does send information of both systems to VRM: its
therefor better to use a Venus GX for systems like this.
• 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
powering the VE.Can network, see Q17 in our data communication whitepaper.
2.3.2. Battery Monitor BMV-700 series; and MPPTs with a VE.Direct port
Direct connection via a VE.Direct cable is limited to the number of VE.Direct ports on the device (see Overview of Connections
[3]). 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 BMV-700 and BMV-702. Not for the
BMV-712, MPPT solar chargers and Inverters with a VE.Direct port. See next paragraph for more information on that VE.Can
interface.
Connecting more VE.Direct devices to your CCGX than number of VE.Direct Ports
First of all, note that the maximum of VE.Direct devices that can be connected is GX device specific, and constrained by the CPU
power. It may also be reduced for very complex systems, such as many AC PV inverters or synchronised inverter chargers, etc.
So always allow some additional headroom in the design. How they are connected, so direct, via USB or hub does not change
this maximum. See here for the maximum limit on all GX devices Devices.
For the CCGX, this limit is 5.
Then, these are the options on how to connect more VE.Direct products than available VE.Direct ports:
• Option 1: Use the VE.Direct to USB interface. The CCGX has built-in USB ports (see Overview of Connections [3]). Use a
USB-hub when additional USB ports are required.
• Option 2: (Only!) the BMV-700 and BMV-702 can also be connected using the VE.Direct to VE.Can interface. Note that the
BMV-712, MPPTs and VE.Direct Inverters
cannot be connected using this CAN-bus interface as it does not translate their data
into CAN-bus messages. When using the VE.Direct to VE.Can interface, make sure that the VE.Can network is terminated, and
also powered. For powering the VE.Can network, see Q17 in our data communication whitepaper. Lastly, note that this canbus
interface is deprecated.
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 CCGX , and unfortunately
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.
2.3.3. 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)
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 CCGX an MPPT 150/70 needs run firmware v2.00 or newer.
2. You can combine a Skylla-i control panel with a CCGX.
3. You can combine a Ion Control panel with a CCGX.
