Warning, Installation too busy, real time data link disabled

Hello community,

It's been over a year since my system was installed and I've had this problem for only 2 months but I can't find it. I have three MPPT 250/100 connected together to a Cerbo GX, two Multiplus II and a Lynx shunt. The message only appears at the end of Am or early PM and stops in the evening when the PV is low. I don't think it's an internet speed problem because it's the same since 20/1 mbps. Thanks for your help!

Here my installation I have

24 Agm 6v 400amp (3 strings)

40 solar panel 310w connected 8 strings

3 MPPT 250/100

2 Multiplus II 240v

Cerbo GX

Phase rotation Issue

We have a three phase system with 3 Quattros 8000. The Inverters/chargers accept the AC supply normally and go to charger mode but there is an alarm of Phase rotation warning raised on CCGX and VRM

"VE.Bus System - Phase rotation: Warning "

Since the system accepts ACin and charges the batteries normally as well as passing this input to loads why we get this alarm on the system. Can this happen? Any ideas?

Quattro overload warning

Hi all,

I have a 15 kW and 48V Quattro inverter with a 55 kWh battery bank and two AC-Coupled PV inverters.

With no reason and every few days I get an overload warning that always lasts exactly 22 seconds. This issue sometimes happens at night, with almost no load engaged, sometimes happens during at noon, in the evening...

This does not make any sense, I think it is just a flaw in the firmware because it always lasts 22 seconds and happens at any time of the day

Any clue?

System Alarm Grid Lost

For a few days now we've been getting a system alarm that says "Grid Lost." I can highlight it on our CCGX screen, but it doesn't go away. (I.E. The warning triangle in the top of the screen keeps flashing no matter what I do.) It also does not register on the VRM site under Alarm Logs...

We have not lost grid power once in this time period.

I do however use the CCGX's relay and it's automatic Generator on/off rules to tell the Quattro when to pull power from the grid. (I do this so we can use the energy stored in our batteries first.) So while the Shorepower meter shows zero, we are still connected to the grid.

We also have a PV inverter connected to our Quattro's 230v output, which gave me a grid error once, but I've not seen that happen again. (Meaning it might have but then went away before I noticed it...)

Did something change in the firmware to cause us to get this alarm?

We were running 2.51 but it also happened when I updated it to 2.52.

Thanks to anyone that can help!

Spurious inverter temperature warning?

I have a generator connected to AC2in on my Quattro 15KVA. The generator is turned on by Venus GX to charge a battery automatically.

Each time the generator is shut down (when the battery is finished charging), the Quattro throws a Temperature Warning event that then goes through the VRM alarm rule ("Automatic alarm monitoring") and ends up as an email/text message on my phone.

Just one second later, the Quattro then clears the Temperature Warning.

This happens every single time, no matter the actual temperature or anything.

1. Is this normal? Why would the temperature of my Quattro change so suddenly?

2. If this is just a spurious warning that is to be expected and ignored, is there any way in VRM to configure it to wait a few seconds before escalating a warning? Or maybe there is some other way I can filter out this type of false warning.

Temperature L1: Warning


We keep receiving this "Temperature L1: Warning" message in the last period of time, an alarm that's always cleared after a few seconds.

Does anyone have any idea what's this about?

Overload Diagnosis (data included)

Need a little help with an Overload warning. I can't seem to identify the problem. All connections look good. Doesn't show up in VRM, only on the GX. Didn't come close to overloading the inverter's output capacity so can't quite figure out whats going on. Oddly, I get a Grid Lost error simultaneously. From what I Can tell, the inverter never shut down. I've included screenshots from VRM and the logs here, which show the Overload warning, but I can't see anything out of the ordinary...

System specs:

48V 200AH AGM / using 1/0 wire

Multiplus II 48v 3000/35 120

SSCC 150/45

SmartShunt 500A

Lynx Dist

as the title says, how can we disable the very annoying "low voltage warning" in the victron app? i never wanted to set this warning and i can not find any option in the app to disable it. (please see, that this is warning is different from the "low battery voltage alarm")

Relation / Action to Battery temperature

Yesterday my battery temperature rose above 30°C, I got a warning, , no alarm.
But in the charge characteristics I did not notice a reaction of the Quatro.
At what temperature a reaction will be noticeable?

INVERTER OVERLOAD WARNING - Multiplus 48/5000/70

I'm getting an "inverter overload" warning on my 48v Multiplus. These are occurring even when the AC loads are disconnected at the AC breakers.

I've been getting these sporadically (maybe once every 3 months) for almost a year. Normally it goes away if I disconnect the batteries then reconnect them to the multi. However, the latest error message is more persistent and reoccurs soon after the battery is reconnected.

I've searched the group for possible solutions and someone had mentioned updating the firmware to v481 which I have just done, followed by rebooting the CCGX and multi, but the inverter overload warning keeps occurring

There has to be someone in this group smart enough to have some suggestions on a fix

Can I Receive Text Message for Alerts

I have set up my alerts and warnings from my Color GX to generate an email, however I would also like to receive a text message, especially in the case of alerts. Is there any configuration I can do without coding?

Multiplus/EasyPlus Issues: Grid Lost & High Temperature Warnings

Marine EasyPlus install with CCGX.

Issues after last firmware upgrade (469);


As mentioned elsewhere here, the latest firmware versions have addressed excessive fan running time and things seem to have gone from one extreme to the other. Our fan used to run ALOT. Now our fan NEVER runs! We have never had a High Temp warning before. We assume that the new frugal fan program is to blame. It is Australian summer here so ambient temp was in high 20's (deg celcius) but we have had the unit for several summers now and we believe some sort of compromise is needed with the fan program or we fear more warnings and possible damage due to unit high temp.

The more persistent problem is the 'Grid Lost' Alarm. Again these are happening after the firmware upgrade (done so we could access VDCC). We run grid/mains/shorepower into AC Input 1, charge our FLA bank from the mains and atm exclusively use the boiler AC thru-put AC circuit to power our mains kettle etc. We have no ESS tied to grid etc.

When the alarm goes off we have tested the marine shorepower receptacle with a hair dryer and it works fine. The CCGX AC1 Input screen of the multi tells us that shorepower is available ie 240ish volts and 50hz but something has triggered the alarm and cut off grid to the unit even though grid is available.

The issue seems to go away if charger only switch is selected but I can't be sure, it maybe coincidence.


This shot was taken just at the grid was reconnecting but the AC-in L1 had zeros in the Amps and watts boxes but the 244V and the 50.1Hz was showing even as 'Grid Lost' was sounding.

I see that other posters here have had 'Grid Lost' alert whilst still connected to the grid... hmmmm.
