CCGX not displaying alarm notification when it should

In the screenshots below:

  • My battery SoC is 16%
  • The CCGX is set to turn the generator on when the SoC is below 25%
  • The CCGX has (correctly) sent a start signal to the generator.
  • The CCGX says that the Generator Start/Stop state is "Running by SoC condition"

All the above is as it should be.

However, the generator failed to start because of a mechanical fault. Under these circumstances, I would expect the CCGX to raise an alarm notification (after a few minutes), but it has not done so. In the past, it definitely HAS raised an alarm notification under these circumstances, I think the message that I used to get was "Generator not detected at AC input".

The CCGX is on firmware version 2.81 (auto-updates disabled)

My objective is to start getting this alarm message again when the situation arises.

Screenshots below.

VE Bus 276 - low battery alarm when turning on Multiplus II

Some background on my system: I have a 1995 Casita RV with the following power system:


1780 watt Canadian Solar bifacial solar array powering the following Victron components:

4x 12 volt LiFePo4 smart batteries,

1x Lynx Smart BMS,

2x Lynx Distributors,

1x Multiplus II 12V/3000 watt Inverter,

2x Bluesolar 150/70 Charge Controllers,

1x Cerbo GX/Cerbo Touch 50.


Now that I have my system online and charging (thank you Stefanie for the expert advice on the jumper wire :-)

Here's the new issue: The DC side of things works as it should, however, when I turn on the Multiplus II the system tosses out the following error:

VE Bus system (276) - low battery: alarm.

However, the battery bank is not anywhere near low - in fact, it is fully charged (see photos below).

I have tried clearing the alarm and re-initializing the inverter - and I continue to receive the same alarm...

Does anyone have any ideas on what may be going on with my system and how I should proceed to get the AC side of the system online and operational?

BMV 712 - can I set alarm on current/amps?

The manual says it should be possible to set an alarm on any reading, but then only describes alarms for voltage, temperature, state of charge.

I really want an alarm to sound when too much current is drawn. Anyone know if this is possible?

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.

Pylontech Internal Failure after adding a third module

Hello everybody,

after adding a third Pylontech US2000, I'm experiencing the Pylontech battery alarm Internal Failure.

First of all, my previous setup:

Multiplus-II GX (Venus OS 2.82), combined with 2 Pylontech US2000B-Plus (according the the part number) and an EM24, configured as a grid tied ESS system (AC IN connected only); grid tied PV micro inverter (Hoymiles)

The setup ran just fine, no problems at all. Even high load (2000W, deliberately limited in the settings) never threw any alarm.


Then I decided to add another US2000, this time it's a US2000C.

The SOC indicator of all modules showed the same number of leds lighting.

I connected the cables as mentioned in the manual and the Multiplus-II GX detected them correctly, the US2000C being the master.

I started to use a fan heater (1400W) the same evening, eventually the new module threw an Internal Failure alarm. Strangely, just 2-3 minutes earlier, the Maximum Cell Voltage shot from 3.29 V to 4.10 V. Just before that event, the Minimum Cell Voltage and Maximum Cell Voltage were just 0.02-0.03 V apart. Switching it off and on got it back working again.

The next days, the error came back again, even at night where there was almost no load (100-150W) at an SOC of 49%.

I kept the modules in Keep batteries charged mode over night. The next morning the Multiplus-II GX still reported being in Absorption mode.

Unfortunately, the error occurred again. So yesterday evening, I started to charge module per module separately (Keep batteries charged mode, all wires to the other modules disconnected). The SOC of all modules was off, especially from the new one. Every module was in Absorption mode when I ended the charge, the difference between the Minimum Cell Voltage and Maximum Cell Voltage was just 0.02 V. Every module didn't light up the SOC leds, so according to the manual, the module was in idle.

So I tried it another time. This time, I had some load (800-900 W, 25 minutes), the error didn't occur. Some time later (1 hour) I had some more load on it again (2100W, 42.6A, 49.56V, Minimum Cell Voltage 3.28V, 4.10V) and the error came back.

Was I not patient enough and should've kept it in Keep batteries charged mode until Absorption ended? Can Absorption end at all?

Does anybody have a clue the problem is and how it could be solved?

Thanks in advance.

easysolar 24/1600/40 low battery voltage alarm

Intermittently charger/inverter LEDs go from normal flashing amber (charge) to alternating amber/red(Alarm) at same frequency. Checked the manual, checked Victron toolkit, nothing to give reason.

System is running on grid. Grid voltage is fine, not dropping. Main AC load is a fan heater drawing about 970W on AC out 0 (passthrough only connection).

No alarms reported in VRM.

BVM 712 shows no issues, voltages match CCGX/VRM.

CCGX shows VE.Bus Error 0, VE.Bus Error 8/11 report is blank (should these be showing?).

When LEDs flashing alternately, CCGX shows Low battery voltage alarm, whether alarm disabled or not.

System is running on grid. Grid voltage is fine, not dropping. Main AC load is a fan heater drawing about 970W on AC out 0 (passthrough only connection).

Also an LED light and low wattage charger on the other AC outs.

Tested fan in unit, as expected not running, but does when needed (like disconnecting AC in). So not overheating.

Solar charge v low due to weather, but charging ok.

House battery 100% at 26.7V.

VE Bus state is storage, MPPT is bulk (configured like that to prioritise solar) and solar is giving about 1amp.

So why is this alarming?

Hi Voltage Alarm

I have a Victron Quattro 15kva + cerbo GX touchscreen 2 X BYD B-Box LVL 15.3kW batteries. Occasionally I see a Hi Voltage Alarm in the VRM Portal. Last two occasions voltage was 54.9V and 57.05V when the alarms were registered.

Is this something to be concerned about? What are the likely reasons for the alarms?

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.

Why is the BMV-712 beeping?

My solar installer put in the BMV-712 to monitor and control the SOC of the lead acid coach batteries in my RV, These are charged by the engine while on or the 48V solar charged battery bank when the engine is off. It worked great for a few days but it's now beeping at me occasionally, usually while driving. The SOC seems to be 98-100%, and all alarms except for a SOC < 50% are off. Any idea why it might be doing this? He looked at all the settings, displays, and histories and doesn't know.

Multiplus Compact Alarm on cold mornings?

Hi all, I have been using a secondhand Multiplus Compact 1600VA 12V for 5 years, with errors every now and then. I take this to be a good run for a secondhand product, but it would be a pity to replace a good piece of gear unecessarily.

On cold mornings (<5degC) the unit wont start, and the Alarm LED light up with no pre warning code. When the day warms up, the unit will start, but makes a loud vibration noise!

Also, sometimes after running for 5 hours or so continuously with a moderate load, the unit will go into alarm mode. In these cases, the battery voltage is still good (e.g. yesterday at 13.4V). I can only think this is due to overheating? The load is never near max (1600VA).

My setup is a Victron Multiplus Compact 1600VA 12V. I only have two LiFePO4 90Ah 12V batteries wired in parallel. These are about 6 years old. I also have a Digital Multicontrol Panel but only use it as a remote control for the inverter. I have a Smart Solar 100/50 hooked up and running throughout the day.


My theories are:

1) the unit is no longer tolerant to extemes of temperatures.

2) I need to hook up the temperature sensor that I never installed?

3) My battery bank is of too small capacity for this size inverter?

4) There is some internal component that is failing


Any ideas? The charger circuit still works fine.

Any way to dignose the error? I think I have a USB connector somewhere...

Alarm notification

Hi,

I prefer to receive my Cerbo GX alarms, especially the bilge as SMS text or on Whatsapp. Is this possible or a possible future development? I only see the notification by email option. I have currently set up an automated task (opdrachten) in iOS but this does not work without issues.

Any help is much appreciated
