Bug in Lithium BMS assistant on Multiplus

Hi,

After updating the assistant using VEconfigure on my 5kVA Multiplus, I got an error message regarding the BMS assistant for Lithium batteries (see the screenshot below).

I assume the error comes from a translation bug, although I'm using VEconfigure in english (I'm located in France).

QUESTION : is this bug gonna affect the assistant ? I'm worried for instance my lithium batteries would get overcharged...

I've updated the Multipus to the latest firmware (2624430), it doesn't change anything.

Thanks

SOC or SOC

Hi,

I'm using a MP (firmware 2624-413) with two BMV-702's (firmware v3.08), one for each parallel battery bank. There's a pretty steady ~50W DC load on the system. The MP is the only charger (using in combination with a AC coupled PV inverter). The SOC as recorded by the MP is significantly lagging behind the SOC as recorded by the BMV702's, see these graphs:

[image]

[image]


If anything, I would expect the MP to be ahead of the BMV-702's, since the MP doesn't know about the DC loads. The BMV-702's also jump from 95% to 100% while the MP's SOC increases only very gradually.

The option "Synchronise VE.Bus SOC with battery" is greyed out (and reads Off) if I select the MP on VE.Bus as the Battery monitor. When I set Battery monitor to Automatic (or explicitly one of the BMV-702's), the option "Synchronise VE.Bus SOC with battery" switches to On. Am I correct assuming that when a BMV-702 is selected as the Battery Monitor, VenusOS will update/sync the MP's SOC with the SOC as measured by the BMV-702?

My first question is: what is the effect of that?

The batteries were still accepting approx 20A (~10A for each bank) when the BMV-702's decided to jump SOC from 95% to 100% which would indicate that the MP's opinion re SOC would be more accurate.

My second question is: why do the BMV-702's jump their SOC instead of showing a gradual increase?

regards,
Jan

VE.Bus BMS, CCGX and MPPT without MultiPlus/Quattro

Hello,


Is it possible to connect a VE.Bus BMS directly to a CCGX (without MultiPlus/Quattro)?


Will this setup allow me to control/end charging from two Blue Solar MPPT 100/50 connected to the CCGX or is it required to use a VE.Direct non-inverted on/off cabel for this - even if a CCGX is present?


Thanks!

Good afternoon,

Is there a solution in the VRM app that the correct data (Time since last full charge) indicates. In the CCGX it does indicate the correct data. Is this a bug?

MPPT/DVCC output settings

Hi all.

I'm installing a victron off gird system in the next few weeks (5kva multi, 250/100, venus gx) and I have a question that has a couple people (and myself) stumped.

Say the mppt was set for 50A max output to suit the batteries

The batterys were at float and a load was switched on meaning the multi was drawing 80A.

Would DVCC allow the MPPT to ramp up to output 80A (if the amount of PV was available) so that the batterys didnt have to supply the extra 30A?


Cheers

AC source symbol changed to grid instead of generator since venus upgrade

Since the last update i noticed that the AC source symbol in the VRM portal has changed from generator to grid. This is on the VRM portal and in the APP

When i change back to an older version of Venus OS it is back to "normal"

All appears to be working fine.

Is this a bug, or can i resolve this myself?

BMV 712 partially clear history data

Goedemorgen.


Today a short question on the BMV 712.

Is it possible to clear only single data from the history?

Background is that I have invalid values in the battery voltage (eg lowest batterie voltage: 4,85V). Of course, I have not had them yet, I think these are still from the installation. Surely I could delete all values, but would like to keep the remaining valid data.

Is there a possibility? Thank you.

System - AC Genset graph in VRM

In "Advanced" menu of VRM portal, there is a graph named "System - AC Genset". I guess the data from this graph is coming from VE.Bus system. Yet, as my VE.Bus is a Phoenix 5000 mono-phase and my Genset is connected to 3 Multiplus (for tri-phase), I do not see the power brought by the genset in the VRM.

Yet, my genset load is monitored by an ET340 meter that could be connected to my CCGX via a Victron RS485 to USB interface cable. My question is:

How to display the data of the GenSet meter in this "System - AC Genset" graph in VRM using the Victron RS485 to USB interface instead of the VE.Bus connection?

Thanks for your help.

I need your help, the Quattro 48/3000 / 35-50 / 50 120V and Quattro 48/5000 / 70-100 / 100 120V inverter / chargers have anti-island protection to deliver surplus to the grid?


Since its datasheet is not mentioned and that feature is not clear.


Or do I need to add other equipment to my system to comply with the protection anti-island?

Unusual Charging Activity by a Bluesolar 150/70-Tr

Hi guys. We have a site that has three solar arrays connected to 3 different 150/70-Tr Bluesolar charge controllers that charge same battery bank. The system has been working very well up to some time this week when we noticed a very strange phenomenon on the VRM regarding one of the controllers. In the early morning hours, it charges well but from around 11 a.m. onwards, the controller drops the charging power abruptly and eventually ends stops charging . See attached images taken about 1 hour apart depicting today's activity. What might be the issue? @mvader (Victron Energy Staff) @Guy Stewart (Victron Energy Staff)

VRM => include 3rd party AC generator via modbusTCP

Hello,

our setup is a standard AC-coupled single-phase multiplus-II based ESS (connected to phase 1). However, we do not have any PV, but a 230 AC fuelcell unit running 24/7 (connected to phase 2).

The generated electricity is continously measured and monitored, and the data is available on a homeserver, but it is not (yet) included in the VRM overview.

To achieve this, I guess I could include another CG 1-phase meter, but I was wondering whether I also achieve this by:
- setting up a modbusTCP server on the mentioned homeserver and
- asking the Venus GX device to look to the modbusTCP server - pretty much as if it was an SMA PV inverter (=> https://www.victronenergy.com/live/ccgx:ccgx_sma)

For this I would have to make the modbusTCP server look like a SMA PV inverter.

I've also seen a rather old entry in google groups:
https://groups.google.com/forum/#!msg/victron-dev-venus/TN7iwVdr-uQ/zhTzPIT5DgAJ

My preference would be a solution where I do not need to customize the VenusOS install, but I'd like to ask, which solution would be the easiest/preferred.

Thanks for any comment/suggestion/hint.

I have some issues on the VRM main dashboard. The consumption chart is not displayed on the dashboard, there is only the PV production and battery SOC.

For information my system has a VENUS GX, a Phoenix Inverter Compact 24/16000 (VEBus firmware starts with 19), a Blue Solar 150/70 and a BMV700.

Does someone have this issue or can someone have an idea on how to get the consumption chart on the main dashboard of the VRM. Thanking you.

Multigrid II issues

Hi,


I have 2x Multigrid II's in parallel with a Fronius 5kW AUS on the load side with the entire house. I have a BYD 10kWH battery in the IP56 cabinet

When first programmed and commissioned it seemed to work fine until the PV turned off, then the battery seemed to export to the grid.

The next morning, once the PV started back up, the battery re charged, but whatever the PV was putting into the battery, it was also importing the same amount from the grid into the battery. This went on for weeks with support from The Netherlands and Ciaram from My Energy SA trying to solve the issue. Eventually with Ciaram's help, we updated the firmware which had come out that day and we didn't have any issues.

Three weeks later after everything had been running smoothly, the Master Multi went out on overload and shut down power to the house. We have now bypassed the entire system and he is now back on grid only.

Nobody was home at the time this happened, the customer didn't know until he got home for lunch that day. According to VRM it happened about 0755 in the morning.

I have not yet been back to site since, and it won't let Ciaram remotely reset the Multi for some reason.

Has anyone else had a similar issue? What should I look for once I'm back on site?

Ciaram and Wayne from My Energy SA have been very helpful, but just thought I would ask on here as well.


Thanks
