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 Color Control GX 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, whether via VE.Direct, via USB or USB hub,
does not change this maximum. See the Victron GX product range for the maximum limit on all GX devices.
For the CCGX, this limit is 5.
Options to connect more VE.Direct products than available VE.Direct ports:
1. Use the VE.Direct to USB interface. The CCGX has built-in USB ports. Use a USB-hub when additional USB ports are
required.
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
CAN-bus 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.
4.3.1. DC load monitor mode
If you wish to use a SmartShunt or BMV-712 to monitor individual DC circuits, rather than as a whole-of-system battery monitor,
you can change the Monitor mode setting from Battery Monitor to DC Energy Meter in VictronConnect.
If DC meter is selected, you can then select the following types (also in VictronConnect):
Solar charger, Wind charger, Shaft generator, Alternator, Fuel cell, Water generator, DC-DC charger, AC charger, Generic source,
Generic load, Electric drive, Fridge, Water pump, Bilge pump, DC system, Inverter, Water heater
Once connected to the Color Control GX, the type and the amps and power of the DC load is shown in the user interfaces and
available on the VRM Portal.
When configured as type “DC System”, the CCGX does more than just recording and visualisation:
1. The power shown in the DC system box is the sum of power reported by all SmartShunts configured as such. Allowing
multiple meters is done to accommodate for example a catamaran, so you can measure the DC Systems on Port hull and on
Starboard hull.
2. The DC system current is being compensated for when setting DVCC charge current limits to Multis, Quattros and Solar
Chargers. For example when a load of 50A is being measured, and CCL by the battery is 25A, the limit given to the Multis &
Solar Chargers is 75A. An improvement for systems with significant DC loads such as Yachts, Coaches and RVs.
Notes and limitations:
• This feature is available for SmartShunts and BMV-712. Not for BMV-700 or BMV-702.
• Setting the meter mode is done with VictronConnect, in the BMV/SmartShunt itself. For details see the BMV-712 or SmartShunt
product manual on the Battery Monitor product page.
• The NMEA2000-out feature does not support these new types, for example when using a SmartShunt to measure output of an
alternator, that data is not made available on NMEA 2000.
