VRM grid lost alarm will not clear

I labelled my Quattro AC input 1 as ‘shore power’, then set up an alarm rule on my CCGX where all input labels (not available, grid, generator, shore power) were enabled.

When I disconnected my shore power, the CCGX and VRM gave me ‘grid lost’ alarms. I acknowledged the alarm on the CCGX and reconnected shore power but it took a reset to clear the CCGX, and I can’t clear it on the VRM.

I’ve tried deleting the rule and setting up a new one, re-labelling my input as ‘grid’ to see if that’ll clear it - no luck.

Any advice appreciated - would like to clear from the VRM.

Two Multiplus in RV

I have two Multiplus 3000 mounted up in my 50amp RV. I want to run a leg from each phase coming in to each Multiplus. That way each side of the breaker panel has its own Multiplus. Has any one done this? How would you wire the Color Controller? Just run the Cat to one and run another Cat from one to the other? Would it work that way?

The Multiplus' run fine, charge as they should and power everything just fine running a leg each. Should I just parallel them and be done with it or can this work? Any help would be appreciated.

Best configuration for Narada 48NPFC100 in Multiplus II

Hello, I need help to configure a Multiplus II 3000 with 2 Narada 48NPFC100 lithium batteries in a PV system with 2 SMA Sunny Boy 1.5 in an off-grid system. The system is working fine and charging the batteries until for some reason unknown to me, the Multiplus raise the frequency and shuts down the SMA inverters (also the electricity in the house) even when the batteries are not fully charged. My supplier in Chile for both Narada Batteries and Victron Multiplus doesn´t answer my queries and I don´t trust in the batteries and charger configuration (VEConfigure and ESS) that the supplier gave me earlier. If more info is needed please ask me for it. Any help will be very appreciated.

PS: may be @NicoV or @Daniël Boekel (Victron Energy Staff) can help me? Thanks!!!

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.

Color Control GX making noise

I got my Color Control GX hooked up today and I noticed it makes a constant noise. I wouldn't call it a buzz. More like a muted white noise. Or maybe the sound of a loud speaker being but not playing music yet. Its not crazy loud or anything but you can hear it when close to it.

Is this normal?

CCGX crash and alternating device IDs

I have a rather complicated set-up(*).

Today my CCGX went through periods of rebooting continually. There is a single BMV connected to the CCGX. During the crashes, it seemed that the CCGX was assigning the BMV two different IDs (289 to start, and 288 to end). What would cause this?


(*) I have a 48V and a 24V system. They are connected by an MPPT (not connected to the CCGX).

There is a single CCGX

The 48V and 24V each have a MPPT connected to solar panels (each connected to the CCGX).

The 48V has a third-party BMS connected via CAN to the CCGX.

The 24V has a Victron BMV connected to the CCGX.

There is a Quattro connected to the CCGX.

There are two Oceanvolt motors connected via CAN to the CCGX.

Feature request: Add a Time-to-go indication to CCGX screen and VRM.

On the BMV (battery monitor) we have a screen with TTG (Time to go), indicating the time the battery will last with the current load (profile). It would be great to have a (customizable) "Time to go" indication on the CCGX overview screen. (And maybe also in VRM.) The feature would be great for situation where you depend on the battery and you have to adjust loads to make it through the night, for example. I have customers that removed their diesel generator and run their house completely with a solar-storage system. It would be very helpful if they have an indication if their battery is going to make it until the next morning and if they then can adjust the loads in their house, if they see that the battery will not make it.

Thanks in advance for considering this!

Connecting CCGX to Quattro inverters and NMEA network

I currently have four Quattro inverters connected to a CCGX through the VE Bus port. Does anybody know if I can connect my CCGX to my NMEA network via the VE Can port at the same time without crashing something? My goal is to be able to pull system data through that connection and display it on a computer elsewhere. I assume that wouldn't affect how the CCGX is currently controlling my inverters. Unfortunately the diagram in the manual isn't clear as to whether this is possible. Normally in such a situation I'd give it a try and see what happens - but I had a couple faulty CCGX units installed on this system previously and I'd hate to have to replace one again if it locked up.

MPPT 12v 100/30 Status offline


I have an 100/30 MPPT charge controller that shows status offline.

I have done the following when fault checking.

1. Checked connection and fuses - all good

2. checked the load from the panel to the MPPT - all good

3. run the battery and a load from the MPPT - it is working just showing status offline.

4. Updated firmware - all good

5. removed connection from solar panel and battery, left off for 2 minutes then reconnected. Status is the same.

6. removed the app and reinstalled the app on my phone, including disconnecting Bluetooth.

taken the vehicle back to the installer, who double checked wiring, fuses and connections- all good.

has anybody had the same experience and found out a remedy? why is the Bluetooth app not showing the graph information and showing status as offline.

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?

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).

No Smartsolar MPPT showing on color control GX display

I just installed a Smartsolar 150/100 VE.can enabled charge controller and connected to my Color Control GX and it's not appearing on the display.


I have dual Multiplus inverters connected to the VE.bus and the charge controller connected to the VE.can port, both terminators in pace as shown below:


The Vconnect bluetoothed to my phone shows the CC is working fine and producing power, no problem. I've changed cables, swapped everything around, rebooted, shut down numerous times, updated firmware on all components, but still nothing on the display for the CC. I do see the "charger" in the system settings and it sees the Smartsolar with correct serial number and firmware version - so the CCGX "sees" the CC, but won't display power info:




I checked the TX/RX settings - all per the instructions, normal, etc.

What next? I must be missing something. The CC works great, just won't show up on the CCGX :-(

How to see SOC on Easy Solar 24/3000/70-50 MPPT Colour Control Inverter Charger system

I have just had a Victron EasySolar 24/3000/70-50 MPPT 150/70 Color Control Inverter Charger System installed in an off grid setting, trying to make sense of the manual [which says for a multiplus so poss wrong manual? or is the EasySolar a MultiPlus?] though there is also a Smart Solar charge controller manual, [lists lots of various mppt] but can't really make any sense of this either. Basically would really love to be able to work out how to see the batterries SOC [state of charge] which is how I used to guage my old system, Firstly on the Color controller GX, Then I think I have connect to it online but can't fathom that out either, not sure if I some sort of wifi dongle {where would I plug it in as the color controller is attached to the inverter/charger] or plug in an ethernet cable? I have been trying to research it from the Victron site, but so many pages link to other pages that don't seem to function & I am getting more confused.

We used to have a 12 volt system & this one is now 24 volt so also quick question, before I could gauge my batteries by the dc voltage [Not wanting it to go below 11.5] now as this is a 24 volt system on the color controller in the bottom left hand battery icon, its states around 25.1 v -1.4A [fluctuating] is the 25.1 v the battery voltage as its on a 24 volt system [so 2 x 12 would be 24] so 25.1 is Ok & I guess if it goes down to 23v this would be equivilant on 11.5 on a 12 volt system.

It seems such a shame that there doesn't seem to be any guide on the victron site or in the manuals what this wonderful colour controller images mean! for non tech savvy folks like me

Thanks in advance

CCGX hardware problem detected #42

My Color Control GX (firmware v2.58) has been working flawlessly for a number of years but started beeping last night, with the notification "Hardware problem detected #42, storage is corrupted on this device". I have seen where others on these forums have indicated that it needs to be sent in for servicing, but have also seen a post where someone suggested they were able to do a file system check command (fsck) to repair the partition. So I am wondering if it might be possible to do this myself without sending the unit in to get serviced. I have experience with BSD but have never worked in Venus.

Install of both BMV-712 and Color Control GX

I noticed in a post of couple of years ago that both the BMV-712 and CCGX were needed in order for the CCGX to monitor the battery. Isn’t it true that this is no longer the case? With the release of the SmartShunt, there is no need for the BMV-712 as the SmartShunt can be connected directly to the CCGX via VEBus. I still see some installers installing both devices but my thought is that you only need to do that if you are NOT using a SmartShunt. Can anyone confirm this? I have the SmartShunt & CCGX combo and don’t see where a BMV-712 gives me any additional capability.

I hope the installers are not doing it out of habit if its not necessary.

Improved performance CCGX

Wrapping up an install on a boat with CCGX, 3x MPPT, 2x Multiplus, Wakespeed regulator and finding that CPU utilization is always over 4 and frequently hitting 5 on VRM diagnostics.

Was hoping to use Grafana for some custom displays, but it looks like the CPU is so maxed that real time data via MQTT is not possible.

Tried shutting off NMEA2k, and all other non mission critical services with limited improvement.

Not experiencing any reboots and the system generally runs well, but it's clearly maxed.

There is no space for a Cerbo and the cutout for the CCGX display is very different from the CERBO display.

Are there plans to release a CCGX with improved capabilities any time in the future?

Grid independent ESS

I have a multiplus ii 48/5000/70-50, DC PV array, Battery with built in BMS, MPPT and CCGX running ESS.

I want the system to run grid independent - using only PV and battery unless battery gets too low or load gets too high.

We have a very unstable AC input with large fluctuations of input voltage that result in regular inverter overloads and grid disconnects, even when the grid is available.

We have used the programmable relay assistants to prevent AC 2 out disconnect with the grid disconnections. (This is working well)

I want to use the Generator Start - Stop assistant to ignore AC input above a specified SOC and below a specified AC load. The point is to minimise exposure to the unstable grid input, but have it available when needed.

I have created the following config... not yet uploaded...




Will the assistants work together to give the outcome described above?

Is the order of the assistants correct?

Is there anything here that could cause damage to my system or electrical appliances connected to it?

Any other smart idea to fix the issue ? Or shall I reach out me reseller 600km away for warranty ?

If anyone from Victron sees this, VRM id is fc6947c33374 and remote support is enabled.
