EVCS wifi connect to CCGX ?

Im asking this question as a professional Victron installer, I propose to install a EVCS into a clients MP 3 Phase ESS system, they currently have CCGX with LAN connected. My question is will the EVCS connect via wifi to CCGX? and would i require a simple Wifi dongle? Can we have both wifi and LAN operating at the same time?

Victron Multi RS Solar 48/6000 connect to VRM (CCGX or RPi)

Hi everyone,

Can someone give a bit more clarity on how to bring the Multi RS in VRM?

The manual is... limited in this regards.

I have a CCGX (on my existing quattro installation) and just bought a RaspberryPi on which I installed VenusOS and I also purchased a MK3 adapter.

From what I can tell, only VECan is available on the Multi RS, but when I connect to CCGX it won't show anything. Do i need the little RJ45 end plugs (which didn't came with any device...) ?

What would I need to connect it to RPi?

  3. Entered the name of the Old Installation to confirm.
  4. VRM greys out.
  5. Can scroll up and down but nothing else.
  6. After 5 minutes still unresponsive kill the VRM app.
  7. Rebooted Cerbo.
  8. Old data not transferred.
  9. Old Installation still showing in VRM.
  10. Go into VRM and old installation shows attached (formatting seems to have got messed up).

Multiple Tank 140 to CCGX


Can I connect multiple Tank 140 to a CCGX. How many Tank senders would the CCGX recognise ? The CCGX has two USB inputs, meaning 2 Tank 140 ? or can I connect more via a USB hub ?

The question is answered for the Cerbo GX, but is the CCGX the same ?

CCGX Firmware update over v2.18 results in stuck at Victron Boot Screen logo

Hi all,

I'd like to update the fimware of the CCGX unit in my EasySolar 24/3000/70 to the latest version.

Anything over v2.18 results in the CCGX being stuck in the Victron logo Splash screen on boot.

I tried updating it via Wifi, the SD card via the 3 button boot menu procedure and with and without the CCGX connected to anything as suggested here.
Tried replacing the USB cable aswel to no avail...

The SmartSolar and Multi plus units inside the EasySolar never gave me any issues and I could update them to their latest versions.
(Currently both running on the latest stable release candidates.)

With v2.18 running the CCGX sometimes looses all readings on the SOC and/or spontaneously reboots.

I'd like to update the CCGX to the latest version (v2.98), any idea's what I might have overlooked or can try?

Thanks in advance for your input !

CCGX, EasySolar II and Pylontech

Hi all.

Salesmen have sold a job that I'm a little unsure about on paper. Have a 3kW EasySolar II with Pylontech setup (straightforward as have done many of these), alongside this though is a separate Colour Control GX device which will be situated in the living area of the home to allow for easier monitoring of the system.

Having a read through the manual I noticed it mentions difficulties setting up the CCGX if using VE Bus managed batteries. However with Pylontech being BMS Can, I'm just curious if it will be as simple as running a VE Bus and power cable from the EasySolar II out to the CCGX, standard VE Can to BMS Can on the battery and away we go as per usual? Or if there is anything else that might cause me some hiccups?

Cheers in advance.

Victron Color Control GX compatibility with LG Chem M4860P2S and Victron Quattro

I would like to replace a faulty controller (Blue Hybrid Energy controller) IMG_0550 conv.jpeg in an existing system that has been in operation for 5 years. The system has Victron Quattro inverters IMG_0551 conv.jpeg and LG Chem batteries IMG_0554 conv.jpeg IMG_0545 conv.jpeg.

The system also has a generator and air conditioning that needs to be controlled by the controller IMG_0548 conv 1.jpegIMG_0553 conv 1.jpeg

The idea is to replace the existing controller with Victron Color Control GX. Issue is compatibility with existing system.

Carlo Gavazzi EM111 feed-in feedback loop


I recently installed an EM111 Carlo Gavazzi meter to monitor my grid connection point to limit my grid feed-in.

To make the meter work, I had to change the meter parameter "Measure" to "b", such that reverse power flow would read as -ve and forward as +ve. When set up like this, the Victron system works perfectly.

However, after a couple days, I am finding this "Measure" parameter changes itself back to mode "a". When it does this, all power, even feeding-in to the grid, is labelled as a +ve power flow. The Victron sees energy being consumed, and then raises it's feedback to combat it. The system is actually feeding in this power, so this results in a positive feedback loop until the Victron maxes out.

Would Victron be resetting this parameter via the modbus RTU? I have seen no indication in the EM111's manuals that they would self-reset, so I am at a loss. Any help would be greatly appreciated!

My system is as follows:


Quattro 10KVa

EM111 connected to RS485-USB adaptor in CCGX

2x 150/45 BlueSolar MPPTs

400Ah 48v Lithium CANBus Battery Set.

ColorControl lost Connection to MPPTs, broke after firmware-flash


a few days ago, my ColorControl lost the connection to the BlueSolar MPPTs. After reboot, it worked for some seconds an then the values from MPPTs were not longer updated. In ESS-Mode they stop working. I tried to connect one MPPT with USB-VE.Direct cable, but it also just worked for a few seconds.

I then tried to flash the latest firmware. Was 2.18 before and I installed 2.87 from SD-Card. But after the installation-reboot, the ColorControl did not start anymore, just hangs in bootscreen. After more than one hour, I decided to fore a new reboot, but it's not working anymore.

I used the Serial Console to connect to the device, enabled the kernel-boot-messages and this is the last printed output:

The strange characters at the end appear in two steps. When I then insert the SD-card, some more of this characters appear. It seems, they are simply console output but with wrong baud rate or so.

Have you ever seen this behavior before? Is the ColorControl simply broken or is there a chance to recover from this?

CCGX not reporting properly to VRM

Have a system where we have recently added a second Fronius inverter to Multiplus.

The CCGX itself has been configured accordingly and is able to see values from both Fronius PV inverters. However, through VRM the customer is unable to see productions values from the new Fronius.

It’s as if the information is simply not being forwarded through to the VRM properly.

Has anybody had any experience with a similar issue and have a potential workaround?

Cheers in advance.

Reporting Generator AC supply source in VRM portal

Hi, I have a multiplus II (not a quattro) installed on boat with CCGX controller. I would like to be able to identify the incoming source of AC power and report it to VRM. The multiplus has inputs that I could trigger with a contactor when the generator is running. Can these be used to advise the GX that the AC input is coming from the geni rather then shore power?
