How Many Ac Current Sensors Can I Connect In One Ve.bus System?; Issues With Multi Not Starting When Ccgx Is Connected - Victron energy Color Control GX Faq

Last update: 2020-10-15 10:33
Data usage depends heavily on amount of connected products, and behavior and usage of those
products. The measurements below are an indication only, and taken from a system with one Color
Control GX, one Multi, one BMV and one MPPT. Log interval set to 15 minutes. If you are on an
expensive data-plan, do make some fail-safe.
Data consumption per month:
VRM logging: 15MB download, 45MB upload
Remote support: 22MB download, 40MB upload
Update checks: 8MB download, 0.3MB upload (This does not include the update itself)
2 way communication: 26MB download, 48MB upload
Mentioned megabytes do not include the download of a Color Control firmware update. Firmware
updates of 60MB are not uncommon.
Q19: How many AC Current Sensors can I connect in one VE.Bus system?
The current maximum is 9 sensors (since CCGX v1.31). Note that each need to be configured
separately with an assistant in the Multi or Quattro to which it is wired.
Q20: Issues with Multi not starting when CCGX is connected / Caution when
powering the CCGX from the AC-out terminal of a VE.Bus Inverter, Multi or
Quattro
NOTES:
1. We recommend to power a GX device from the battery. Not from the AC-out. In case you still
power it from AC-out, carefully read this FAQ item.
2. This FAQ item applies to Venus GX, CCGX, and all other GX Devices, but not the Cerbo GX. It
has an improved design due to which its no longer recommended to cut pin 7 of the VE.Bus
cable when powering the GX device on the AC-out port.
3. Make sure that the GX device and MultiPlus is running the latest firmware version.
If you power the CCGX from an AC adaptor connected to the AC-out port of any VE.Bus product
(Inverter, Multi or Quattro), then a deadlock can occur after the VE.Bus products are powered-down
for any reason (after any operational fault or during a black start). The VE.Bus devices will not boot-up
until the CCGX has power ...but the CCGX will not boot-up until it has power.
This deadlock can be rectified by briefly unplugging the CCGX VE.Bus cable at which point you will
observe the VE.Bus products will immediately begin to boot-up.
This deadlock can be avoided in two ways:
Power the CCGX from the battery; or
Cut pin 7 in the VE.Bus cable connected to the CCGX
Cutting/Removing pin 7 of the VE.Bus cable to the CCGX (brown/white according to standard RJ45
ethernet cable colour coding) allows the VE.Bus products to start up without waiting for the CCGX to
boot up first.
