CCGX Color Control Image

CCGX Color Control

Quattro stuck in "off" status and will not start

My system is grid connected ESS. Quattro 10000 + CCGX. Battery status ok at 48vdc. I switched off system due to some tripping issues caused by unknown house fault (I think it may be well pump). We were away so I wanted to ensure the system stayed powered from grid for the freezers. Now the system will not reconnect. CCGX shows Inverter as "off" so no AC input and no battery status. I can switch on the Quattro and it goes to "mains". But as soon as the CCGX is connected the system shuts off. I have tried "redetect" in the CCGX but it does not do anything. Tried rebooting but no difference. System will run off the grid OK until I connect the CCGX cable and then it shuts down. I tried switching quattro on via CCGX but this does not work in ESS.

No ESS assistants detected on CCGX. I checked the system via dongle and everything is loaded as it should be.

How do I get the system to detect the Quattro and restart in ESS mode again?

Color Control GX hanging, freezing

We are experiencing an intermittent case of a Color Control GX hanging, or freezing. The normal symptoms are the display looks live with an indication of AC input and battery charging etc. But in reality it has hung and showing a state that it was in when it hung.

So the first question is this common and can it be cured?

The firmware is latest and its connected to four BV700s, a Quattro and Ethernet. It is using MODBUS to communicate with PLC electrical variables and MODBUS via PLC HMI controls max AC input, i.e. 16A, 32A and 63A shore power.

There is a degree of worry that there might be an issue where the Quattro in conjunction with CCGX may be creating the hanging and thus reluctant to treat this as a pure CCGX issue. The reason for this is there have been some issues where Quattro has not always being doing exactly as expected and have experienced issues where after a hanging we can only get everything looking right after a number of resets of both Quattro and CCGX.

One of the most odd indications of something is not right is the MODBUS command to switch between 16A and 63A works fine and the CCGX shows the correct value on change. Thus that looks good. But when in VRM the Input Current Limit is showing 32A. Also I cannot connect to CCGX in Remote Console on Desk PC, Laptop or iPhone App, irrespective of what network I'm on. So something is not right.

Any thoughts welcome. Thank You

CCGX VRM remote firmware update 1342 error


I've a CCGX running 4.28 and a Quattro that is shown as not updeatalbe 1342:


Following the FAQ Q2:

I understand this is the reasons why I can't update it:


What I'm unsure if the reasons why is really that the CCGX hw is too old or it's the quattro that it's too old? The FAQ refers to the CCGX but what confuse me is that it's the Quattro being a MK2 rather than a MK3.

Can anyone confirm replacing the CCGX with a newer hardware would allow remote firmware upgrade on my Quattro?

Thanks a lot in advance

Measuring energy from single-phase PV Inverter on the second phase of Energy Meter

The Victron Energy Meter Manual for the EM24 RS485 states:-

Single phase dual function

If you are considering using a 3-phase meter in a single-phase installation to measure the grid on one input of the meter and the PV inverter output on another input of the energy meter, use the ET340 instead"

Is that because the EM24 counts total power, with net differential readings from each phase cancelling each other out, whereas the ET340 counts energy on each individual phase and then sums those values?

Also, the EM24 FAQ says "Attempting to use other brand battery inverters and trying to substitute their lack of data connectivity to the GX device by using Energy Meters will not work as expected"

My system was installed with an EM24 doing exactly that. Has that now been deprecated and it is no longer possible to set an Energy Meter as a dual "Grid + PV invertor" function anymore?

Monitoring daily total AC output on Multiplus?

I just want to be able to look at the total power inverted by the Multiplus. I can make a widget on the CCGX which makes a nice graph so it is obviously storing that data but I just want to see the value in KW much like I can with the DC power consumed from the batteries as monitored with the smart shunt.

Is this possible?

CCGX Firmware 2.42 Beta AC and DC readings

CCGX Firmware 2.42 Beta The problem I have is the AC reading and DC reading i.e. when in normal inverting mode there’s no problem but when I use my generator the AC out put goes from 16 to 4 watts the DC goes up from say 80 watts to 160 when the battery’s are fully charged the reading are about the normal but when the water pump kicks in the reading on the DC go up which is ok but the AC output takes a dive from 16-20 to 4-0 watts I have checked this with previous version of firmware 2.41

Multiplus with switched AC inputs generator and mains

Hi, We have a system with Multiplus, SmartSolar MPPT, BMV and CCGX plus a custom switchbox for mains or generator input. The CCGX relay starts the genset based on battery SOC (different levels in normal or quiet hours) but it thinks the generator is the only input because of course the Multi has only one AC input.

(I know we should have bought a Quattro, but we were in a crisis and there wasn't one in stock within the timeframe, hence the custom solution)

The switchbox won't allow the genset to be started (despite the command from the CCGX) if there is mains power. This has the advantage that the genset shuts down automatically when mains power comes back, without any intervention from the Multi or CCGX. On the other hand, the CCGX won't close its relay to start the genset if there is AC into the Multi since the SOC can only fall below threshold if there is no mains power.

Would it be possible to program the CCGX to recognize two AC inputs, Generator and Mains, based on: if a generator start has been commanded the input is Generator; otherwise the input is Mains? I guess that would be a custom mod to the software and we would need someone to do that for us.

Other ideas welcome!

Colour control gx wired connection stopped working

Hi There

I recently replaced my wifi router with a TP Link Deco X55. The VRM portal had worked seamlessly via a wired connection to my previous router for over 2 years. Within hours of installation the connection failed with #153 Connection Error {Errno -3} displaying on the CCGX. I managed to restore the connection eventually by unplugging the network cable from the back of the GX device and rebooting. The connection however only lasted a matter of hours before failing again.

I have subsequently installed a nano USB wifi device and all now works seamlessly.

Is there something I need to do or will I have to live with my solution. The local South African Victron people want me to send in the GX unit which I believe to be totally unnecessary.

VRM shows 0W PV Power, Grid shows only Critical Load not whole house consumption


In November 2022, VRM started showing ‘AC Loads’ as 0W and ‘Total Consumption’ & ‘Grid’ displayed only the Critical Load, rather than the figures for the whole house.

My Solar PV was fitted 5 years ago by a Victron dealer who has since gone bust and now the only Victron agent in Kent wants £780 to look at it. He told me to update the CCGX firmware from v1.74 to version v2.92 which I did (with trepidation) but I think this has made my situation worse.

Until this week, I knew nothing of PV systems, so please allow a little latitude while I try & explain;-


I believe i have a HUB 4 system, now known as ESS. It comprises: CCGX, MultiPlus Compact 12/1200/50-16, 3 x Lead Acid batteries, 2 x Solis PV Invertors and an EM24 energy meter. The EM24 is linked to the CCGX via Cat5 cable, but I think it is a serial model with an RS485 to USB interface hidden behind the CCGX.

The CCGX Settings (firmware v1.74) contained ‘Wired AC sensors’ and the EM24 appeared as “BQ21600350013” where it was set to ‘Grid meter + PV inverter’.


In firmware v2.92 there is no ‘Wired AC sensors’, but the EM24 appears under ‘Energy Meters’ but can only be set to ‘Grid meter OR ‘PV inverter’ (not both). The Phase type ‘Single Phase’ and ‘PV inverter on phase 2’ with ‘AC Input 1’ have been carried over from the previous firmware.


Whatever I do, I cannot get the EM24 to appear in the CCGX ‘Device List’. I think it is Modbus RTU (different to’ Modbus TCP’) but in desperation I enabled ‘Modbus TCP’ in ‘Services’ and scanned but of course nothing was found. Help! I am really out of my depth.



All I know is that VRM displayed accurate Grid and Solar figures up until November last year and no hardware has been changed. The EM24 local display is still showing the Grid on L1 and the PV Invertors on L2 so my theory is that an automatic CCGX update to v1.74 lost the connection with the energy meter and upgrading to v2.92 has not helped.



I have found that Victron now say “using an EM24 to measure both Grid and Solar PV on a single-phase installation does not work properly”, and they recommend using an ET340 instead. Is that because the firmware does not support the EM24 anymore? If so, what version of firmware will I need to downgrade to, in order to restore VRM back to reading correct Grid and Solar figures?

Lastly, am I doing any harm running the system without a Grid/Solar meter? I know it is still saving me energy because on a recent bright day, my smart meter was showing 0 watts and the EM24 had a negative figure on L1), I don’t think the solar battery was charging.

Pylontech High Voltage Alarm

Hi I'm getting hIgh Voltage warnings on the CCGX. I understand the cells need to internally balance as it's a new system. They are, slowly, day by day.

My issue is that I have set the DVCC to 53.2V to mitigate the alarms and to allow the cells to balance but it's not stoping the alarm!.

Any ideas?

The alarms currently trigger just above 52V.

Will the Fuse LEDs on Lynx Distributor illuminate without the 4-pin cable supplied with unit?

Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).

Orion-Tr Smart, VE.Direct and integration with GX devices?

Hey there, as I commented on the blog post,

"I'm curious if future versions will have VE.Direct or some sort of integration like that with GX devices? Currently, it seems that the MPPT and MultiPlus are able to coordinate their total charge rate with external BMS via the GX devices. But it seems that the Orion-Tr does not participate in this?"

I'm wondering if there's a way to integrate the Orion-Tr Smart chargers with the CCGX. In particular, as far as I understand, GX devices can coordinate with external BMS via CANBus to determine the charging parameters of a battery. It seems that the Victron MPPT and Victron MultiPlus can respect these limits via VE.Direct and VE.Bus respectively, which is great and a big reason why I bought this BMS and the suite of Victron product.

Now I'm considering purchasing Orion-Tr Smart chargers, however I noticed that they don't have any VE.Direct connectivity, or any other VE connectivity aside from the Bluetooth one. Is something like VE.Direct, VE.Bus or VE.Can planned? Will Orion-Tr Smart chargers integrate with GX devices?
