CCGX Generator Start-Stop "Do not run genset when AC 1 is in use"

I'm not sure I get the logic behind this?( )

I thought the best practice was to connect the genset to AC1 and shore power to AC2?


"Two AC inputs; integrated switch-over system between shore voltage and generating set The Quattro features two AC inputs (AC-in-1 and AC-in-2) for connecting two independent voltage sources. For example, two generator sets, or a mains supply and a generator set. The Quattro automatically selects the input where voltage is present. If voltage is present on both inputs, the Quattro selects the AC-in-1 input, to which normally the generating set is connected."

Would it be possible to add "Do not run genset when AC2 is in use" as well? (given people are probably already relying on the version with AC1 I understand just changing it to AC2 may not be possible).

ignore generator auto start, when shore power is connected

Finally I will install my auto start/stop panel of my generator.

And now I would like to use the functionalities of the CCGX!

But how to ignore the the auto start, when shorepower is connected to AC2?

Getting real time data from GX without using VRM portal

I am looking to get real time data from the CCGX without using the VRM Portal.
Reason is that the internet here is not reliable and could cause issues.


* 2 each of 10 x 315W panels with SmartSolar MPPT 250/60
* 2 x Multiplus 3000
* 1 x Fronius 5000
* Color Control GX
* 24KW Li-Ion batteries

Reason i ask - i would like to be able to detect when power available is less than demand and shut off via smart switches the heavier using appliances such as the electric geyser, dishwasher, dryer, washer, compressor, pool pump

ie: Cloud cover suddenly reduces available power from the Fronius and demand would exceed the capacity of the 2xMultiplus 3000 (4200W). Say the Fronius is pushing out 5000W and demand is 6000W - meaning the MPs are supplying 1000W. Cloud cover comes along and reduces the Fronius to 1000W, which would result in the MP having to supply 5000W, which it can do for a few seconds, but would ultimately overload it. In this case, would need to react quickly and shutoff the heavier loads until stable sunshine returns.

is this possible?


(Edit: I should mention we are completely off-grid)

CCGX & Fronius Symo - Connected Unknown

Hey there!

I got a 3P Multiplus 48/5000 installation running, with 10kw Solar and ~45kwh LiFe4Po Battery storage. The PV Inverter is an Fronius Symo 10.0-3-M.
This setup has been running totally fine for the last ~2 years.

Now... it's happening EVERY morning, that the solar inverter is no longer present on the main tab, but it still is in the menu. CCGX and Fronius are hard-wired, network settings haven't been touched - but of course, both are in the same network, ( /

The CCGX does indeed 'see' the fronius, the IP address is detected and fine, but in the device list the fronius appears as "not connected", and if I enter its device parameters, it appears as "connected unknown".

As soon as I restart the CCGX (every morning) all is fine and the whole setup is running like a charm until the Fronius looses DC power (sunset). The next morning the above mentioned is happening again.... groundhog day^^.

Any clues?!

Same Fronius PV Inverter appears on 2 Color GX setups

Hi everyone

We're big Victron fans - and are lucky enough to have 2 setups. They each have a Color CCGX unit.

We have 1 Fronius PV Inverter but it is appearing on both Color GGCX displays.

I have clicked Remove Device on one Color CCGX but it reappears - I presume because it is still on the same network.

How can I prevent it returning to the one Color CCGX where it is not actually connected please?

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?

Why is the Wifi connection CCGX dropping out regularly?

I have a Victron ESS system with a CCGX in the garden shed (with solar panel roof) in the garden behind my house. The distance from my Wifi router is around 8 meter.
I have a Nano Wifi USB adapter in the CCGX that connects to the router. The signal strength is indicated on the CCGX at always around 45%.
Now for days or sometimes even max. 1,5-2 weeks the connection is stable, but eventually it always drops out at some point. I then reconnect and then it fine for a few days again.
Why is the connection dropping out every time?
And why is it not reconnecting? I now have to connect manually every time.

Sometimes the reconnection also a few times before succesful. Why is this?

Can Color GX use Wifi for remote VRM comms and wired LAN for direct comms to SolarEdge HD Wave

My system has a Multiplus 2 with color GX and SolarEdge HD wave solar inverter.

I can successfully connect to remote VRM using the recommended Asus USB-N14 Wifi router.

I can also conect the SolarEdge to the Color control via wired LAN.

Can I enable both interfaces to work at the same time. The Wifi is intermittent at this location so I want to use the simple (reliable) LAN connection to the SolarEdge and then use the unreliable Wifi for remote VRM updates.

Is there only one ethernet stack in the Color Control which can only be switched to either Wifi or LAN or is there a way I can enable both, but with only the wifi being used for remote VRM use?

Color Control sees the system fine and displays data after boot, but this is no longer continualy updated. Always been perfect up to the recent update.

If the CC is rebooted, the curent state updates the displayed data. But any change in state, there are no changes to the data displayed. (also echoed on the VRM portal in the Advanced data displayed)

Downgrade back to 2.71 makes no difference.

Internet connection problem in Colour Control


I have enjoyd using Easysolar 3000 in my summer cottage. This off-grid installation has been connected to internet by using mobile phone’s usb hotspot - and this did worked well until MAY 2019.

So last spring -a year ago - usb internet connection stopped working and haven’t worked since. I’ve updated firmwire to latest version several times, tried different phones and connections, contacted national (Finnish) importer...

My understanding is that this connection problem is not due to mobile but instead of Easysolar. I’d love to have this fixed at last now when summer is about to start.

What should I do? Is there a chance that something has broken? Could I buy a and use wifi-dongle to connect wia wlan?

Easysolar temp sensor/CCGX

Hi, doing my nut here.

I have an easysolar 24/1600/40 with ccgx.

Initial problem is that temp sensor supplied with it reads 4-5 degrees high. Searching here, I found that it's possible to correct in the superuser mode of the OS. I set superuser, but the sensor doesn't show up in the device list. And now I'm stuck in superuser mode. It won't let me out unless I enter passwords for user or user/installer. Password checks disabled, CCGX restarted. Can't find any way of resetting/clearing these passwords. Can't remember ever using them, but my memory is terrible, so take that with a big pinch of salt.

So two questions

How to get the sensor to show up?

How to get out of superuser?

DC load on CCGX not indicating load

Installed are Victron LiFePo 12.8v Smart batteries with VEBus BMS, Quattro, Smart Solar MPPT and CCGX in a motorhome which has DC loads (12v lights, refrigerator etc) . Everything is working apart from the DC load readout on the CCGX, which I suspect will result in an inaccurate SOC. When I select "DC Load - ON" on the CCGX config settings, the DC load box appears on the Home Screen, however the dc load box only ever displays "--" even when there is a DC load turned on connected directly to the battery. As far as I can see from the setup manuals, the Smart batteries should show as a selectable option in the Battery Monitor list, however only the Quattro on VEBus appears as a battery monitor option. The battery monitor function has been turned on in the Quattro VEConfig. Anyone able to suggest what I may be missing?

Color Control wrong date/time - ethernet connected - must be manually set?


Firstly - love my VRM system. Had very little problems with it since it's been set up for more than a year now. However, one niggling thing lately that has me confused.....

My Color Control is running the latest firmware and connected to the internet via ethernet.

We have had a couple of grid power cuts recently and it seems that the Color Control is unable to set its time/date? Which I find confusing because it's such a clever system!

I have to go into the control panel and manually update it. Although somehow, it does remember it is October 2020?

Power off - go in to the control, random time is set, and the UTC date is 1-10-20. Why is this? I thought all these systems got their time/date from the internet? I could understand it if it reset completely or if it wasn't connected to the internet. It also seems to remember I'm in the London timezone.

Not a massive issue but as I charge overnight it's messed up a couple of times and I've started the day with an empty set of batteries.

Not sure if a fix could be made available? Or if the unit could get the correct UTC time from one of those time server things.

Anyway, many thanks for producing such a great product anyway!

Which GX device would you recommend? And LTE 4G, or router?


I've tried reading up on the different GX devices, but I don't have the full overview. I'd like some input in regards to what others would choose.

My needs, in prioritized order, is to remotely:

- Open a relay to start the generator. This is an old yanmar diesel with a starter engine, so the relay needs to be open for a few seconds to connect the starter battery with the starter engine, and then the relay needs to close again.

- Turn on and off the inverter part of the Multiplus

- Turn on and off the charger part of the Multiplus

- Any BMS functionality is an added bonus, but not strictly needed

Which GX would you choose?

I don't have wifi with the system yet, so the next question is:

would you choose a victron LTE 4G to remotely operate this, or a standard 12v router?

After a restart of the CCGX the system runs well again (until next night).

Multiplus charging following BMS low cell voltage with CCGX powered by BMS load disconnect pin

Hi I'm using a 3kVA Multiplus with an inverter generator attached to AC input, smart lithium batteries, BMS, MPPT 100/50 and the BMV712. I would like to tie everything into the CCGX.

The CCGX manual suggests powering the CCGX from the load disconnect pin of the BMS.

Assuming I do that, and the BMS senses a low cell voltage, the CCGX will be disabled and the inverter will be disabled.

From the CCGX manual I understand the deadlock that can arise in this case

My question is, when low cell voltage is triggered by the BMS with a CCGX connected to the Multiplus over VE.Bus, if AC is applied to the AC input of the multiplus, will the VE.Bus AC detection module connected to the Multiplus enable the Multiplus to charge the batteries?

This is the section in the manual I am referring to:

When the CCGX is used in an installation with a VE.Bus BMS, connect the Power in V+ on the CCGX to the terminal labelled 'Load disconnect' on the VE.Bus BMS. Connect both negative leads to the negative stub of a common Battery.

A Cautionary word about Powering from the AC-out terminal of a VE.Bus Inverter, Multi or Quattro:

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 will 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.

Thank you
