Hi,

Amongst a couple of firmware upgrades and factory resets to my Cerbo GX, two devices have changed VRM instance. E.g. Smart Solar MPPT changed from 278 to 279. This also affected a GX Tank 140 input.

Is there an explanation for this, and is there a way to move VRM history from 278 to 279? I do not want to lose the history for the original VRM instance device.

Thanks.

From searching and reading and reading and searching it is still not clear whether I will be able to fully control, configure and update my MultiPlus with a MK3-USB and either a Mac using OS X or an iPad using iOS. Is updated advice available on this please?

I found this in the VE.Bus Configuration Guide, at para 3.3.
An MK3-USB is required to change settings and perform firmware updates and settings. And, as that requires a USB port, it is not possible to change inverter/charger configuration or perform firmware updates on a Apple iPad or iPhone.

My latest model iPad has a USB-C port and with its accessory USB-C to USB adapter it can easily work with USB devices, such as the MK3-USB, I imagine.

In case using an iPad is still a no-go, can a MacBookPro with OS X and MK3-USB provide full control, configuration and updating of my MultiPlus?

People often ask me on my YouTube channel whether they should buy Victron or MasterVolt systems for their boats. I tell them both systems are good but I prefer Victron for its openness, easy user controllability and Apple friendly orientation. I always feel nervous in providing this advice, given the unfathomable situation with respect to Apple unfriendliness of the MultiPlus.

Guten Morgen,

Es geht um folgende Anlage:

3 multiplus 5000 / 48v (3 Phasen System)

Cerbo gx mit Display

2 Smart mppt für Solar

Lifpo4 Speicher inkl. 123bms zur Überwachung

die Anlage läuft problemlos aber jetzt soll im Falle der Fälle ein Generator mit angeschlossen werden! Kein Automatik Start oder ähnlich soll alles von Hand gehen! Einfachste Variante ein Umschalter vor dem AC In und gut ist! Wie kann ich aber sicherstellen das nur als Beispiel je Phase 2kw gezogen werden ?

bei anderen Ideen gerne vorschlagen

Hello, I have a lifepo4 100ah aux battery and Victron blue smart 10A charger.

Can I use charger as power supply mode in subzero temps in order not to damage my battery and to run water pump or diesel heater while connected on shore power?

Thanks in advance...

I connected the charger under normal option to a good battery - 12.6v on multimeter - and left it there to charge and maintain for 10 days. When I checked today, battery was hot and had no charge - 10.1v. The statistics are shown in the attached screenshot. The battery now ruined!!

Why

Community, I’ve installed a Cerbo GX. I think I’m happy with the relay functionality. 3v3 octocouple relay to allow power to a 12v fan. The digital inputs are a whole other issue and are doing my head in.
I’ve read the manual and some background stuff but I think I’m not getting it.

1. Are the inputs powered at 3v3? Do I just need to complete a circuit to change the input state, I.e. short across the digital inputs (I don’t think this is the case but I need to check)?

2. So what I‘d like is a digital signal when the bilge pump goes on. Here’s what I think I need to do… Put a relay across the pump power. Have that provide a 3v3 signal to the cerbo digital input. I’m aware that I need a diode or octocouple to protect the cerbo from inductive current/voltage due to the relay coil. The problem is I can’t find such a circuit anywhere.

3. Because I can’t find anything it makes me think I’m way off with my plan. Can you guys suggest a better way of getting an on/off output from the bilge pump?

Thanks in advance,

Hi guys,

When I configure my new Multiplus 12/1600/70 with AES Search Mode enabled to start saving below 12W and stop saving above 44W - the lowest permitted values by Victron Connect (see the screenshot below), the AES actually never starts, despite Victron Connect showing consumption under 10W. When I increase start to about 22W it will properly switch to AES mode, but I would like to go as low as possible. There is nothing connected to AC OUT at this moment.

What could be the explanation for this?

thanks,

Martin

Hi Folks,

I am excited about the tank monitoring capabilities of the Cerbo GX but I see so many different and highly technical posts. I really am hoping that by now there is a "plug and play" recommendation. I have three fresh water tanks and would prefer outside sensor install but whatever is proven and most accurate. I have access to all tanks from the top and sides. I also have the Cerbo connected to a BMV-712 and a Multi-plus inverter by the appropriate wire cables and then on to the Raymarine Axiom Pro(where I will hope to read the water levels in addition to the phone app or VRM).

Appreciate your recommendations.

Neil

Hello, I just added a GPS to my Cerbo and see in VRM it will use the GPS to update the time zone automatically if its not set manually. How do i remove the manual setting that was configured prior to the GPS?

Hi, this keeps beeping periodically (approx once an hour) and the yellow charger light is flashing. Does anyone know what the beeping could indicate please?

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.

Hello!

I am an electrician and planning a ESS-system for my new house in Austria.

3x Multiplus-II 5000 (3-phase) with 48V Lithium-Battery (maybe some Pylontech US3000), with about 6kWp Fronius Symo PV-Inverter connected on AC-Out for higher self-consumption and UPS in case of grid failure.

Is there an extra anti-islanding-relay necesarry, or is the anti-islanding-protection from the Multiplus II enough? I only find the TOR D4 Certificate for Multiplus-II 3000!

Thanks for the Answers!

I have a Smart solar 250/100 Charge controller for a 48V battery system . my loads are flood lights which are above 4kW .
since this controller does not have a dedicated load output terminals so I am using external relays . I want to use the relay port on the charger to drive the load external relay. recently I came to know about street light function inside victron app but I am not sure about its real used-case scenario.

Can anyone guide me whether I can use this function to drive the relay port on the charger which can then trigger the external relay that will turn the load circuit on . My aim is drive my 4KW load at night time only and also take care of battery capacity too .

Ik ben enorm victron fan. Heel mijn boot zit vol met victron zonnepanelen, mppt laders, cerbo CX, multiplus, isolators etc. Ik woon zelfs semiars bij. Maar nu is mijn vertouwen toch wel tot een dieptepunt gekomen, helaas.

Ik heb een paar maanden geleden een Victron blue smart charger (15amp, 12v) gekocht. Aangesloten op mijn parallel geschakelde leefaccu's. Dat waren dure jongens van ca 800 euro per stuk, half jaar oud. Na 2 dagen zag 1 van de huishoudaccu's er zo uit.

[image]

[image]

LEt wel, het was een nieuwe accu van nog geen half jaar oud. Inmiddels had ik de lader er al weer afgehaald. Ik heb diverse bedrijven gevraagd. Niemand kon deze explosie verklaren. De enige verklaring was dat de accu dan wellicht al iets mankeerde. Raar, maar ik kon er ook niets anders van maken.
Inmiddels wilde ik de lader gebruiken om een andere accu, de startaccu(ook 12v uiteraard) te laden, niet wetende dat de lader juist het probleem is. Ook deze accu is nog geen half jaar oud. Een dag later was deze accu ook gesneuveld! Hoe is dat nou mogelijk? Wat was de gemeenschappelijke deler? De victron lader!
Wat blijkt? De lader laadt met een veel te hoge spanning van 16.4volt!

Dit is echt niet OK! Ik zit nu met een enome schadepost, waar niemand natuurlijk voor wil opdraaien. Dit is de reden dat mijn vertrouwen in victron verdwenen is. Ik baal er echt enorm van.

Heeft iemand soortgelijke ervaringen? Zou fijn zijn als Victron zelf zou reageren. Ik stuur met alle plezier de lader naar ze op zodat ze zelf onderzoek kunnen doen.

I have recently purchased a Phoenix 12/50 (1+1) 240V Smart battery charger and installed it on my boat which has 480AH of AGM batteries. I used to have a Projecta 50A charger which failed. I run the charger from either mains shore power at the marina or from a 2000W inverter generator when out sailing. After three days of charging (1 hour per day) from my original generator (a generic version of the Honda 2000i) it failed - it showed overload and stopped generating AC. However even after I disconnected the load I still couldn’t get the generator to run again. The engine runs fine but within two minutes of starting it the AC overload light comes on and the AC circuits cut out. Numerous resets and restarts don’t change this.

So I came back into port and borrowed a generator from a friend to head out again. This is a fairly new Yamaha EF2000is.

On the second day of running this generator it started labouring and the AC cut out though it didn’t show overload. Now the generator will start but runs very slowly and won’t produce power, with the engine cutting out after about two minutes.

I know this isn’t a generator trouble shooting site but my question is - could my Phoenix charger be causing these generator issues as it seems too strong a coincidence that two otherwise perfectly fine generators have failed within hours of having the Phoenix charger plugged in- after years of successfully running other chargers in this way.

Using quality clean fuel so this is not the issue. I am in Australia if this influences frequencies etc.

Would be interested in any suggestions or advice!

I am using Quatro 48V-10kVA inverter with 3 victron MPPT 250-100 charge controllers , Axitec lithium batteries , no grid meter along with Grid to work as backup only. I followed steps to setup ESS for this system but the issue is that whenever I turn on grid along with charge controllers inorder to charge my batteries faster , the inverter shows to be in Passthru mode and solar charge controllers go to 0W (basically they disconect).

When I turn off the grid mcb, the charge controllers come back on and start charging batteries again .. Can anyone guide me on whats set incorrect here that is causing this issue? I will share screen shots of my current ESS settings.

I accidentally zapped my CCGX when touching a button to wake it up and check incoming solar power. I gave it a pretty hard ESD shock. The unit rebooted and seems to communicate just fine to the VRM Portal. I can log in remotely and access my CCGX, but nothing appears on the LCD screen. Actually, I can see a hint of the old image and the back light is working, but otherwise displays no image. Can I repair it? Is there a replacement LCD? I'd rather fix it than replacing the CCGX and having to start over with a different account since the Unit ID is tied to the CCGX ID number.

Thanx,

Shane

I have a Cerbo GX connected to my MPPT and Multiplus via VE.direct. If I power off the Cerbo GX, what is the default operating modes of the MPPT and Multiplus?

My desired case is that my BMS turns off the battery and Cerbo GX and that the MPPT would be turned off.

I can hear a very faint humming noise like a coil whine coming from my smart shunt. Is this normal?

Hi there,

Kindy please can I get some clarification, I have to integrate a lithium [Plylontech] system with an existing off-grid SLA system, there's a few challenges on the PV side but I'm largely confident I've solved them and so my main question is coupling the Growatt 5000ES off-grid inverter to the Multiplus-II,

[image]

Question: What's the most practical option here to connect the Growatt and Victron?,

My gut feel is connect it [Growatt] to the AC In and I'll run the Gen into the AC Input on the Growatt.

The other option I see is connecting the Growatt to the AC OUT (1 or 2) but I need clarification on how the Multiplus will handle grid forming with a fixed frequency/voltage from the off-grid Growatt.

Also if anyone has any tips on this install, I'm keen to hear them.

Any questions let me know,

Thanks in advance!

I have (2)-Multi 12/3000/120-50's in my motorhome and I need to understand how to configure them in a way to utilize 120v(single phase) either 15/20/30amp as well as 240v dual leg.

The motorhome is currently set up with both Multi’s linked, each one is powered by its own 120v leg. I like this as they charge a single Lifepo4(home made) as one unit. So they charge fine off 240v shore or my 240v generator. They will not accept any common(split)120v single leg power though. Both units fault out immediately.

This makes sense as they are linked and are looking for separate legs. I have tried unlinking them by removing the cat cable and some reprogramming of the Multi’s, but no luck. I also tried running with one unit off in different combinations of cable or no cable, still no luck.

The need to utilize single phase 120v is not common, but it is important to have the capability even if requires some physical manipulation such as removing the cat cable and/or running with one unit off.

Hope my goal makes sense. If not ask away.

Looking for some direction or advise.

Thanks

Kevin

I want to operate an electric anchor windlass using the start assist for longer than 30 seconds, so if I connect the +ve up anchor switch to the Cyrix start assist wire, will the cyrix stay closed as long as that button is pushed?

Bonjour,

J'installe un Multiplus dans mon camping car. Pour le 220v, mon électricien Victron me conseille d'avoir seulement un Interrupteur differentiel avec un disjoncteur en sortie de multiplus AC OUT.

La protection en amont du multiplus AC IN étant réalisé par la prise de quai ou le disjoncteur differentiel du camping , ou d'une maison par exemple.

Je me pose la question, d'une probable anomalie à la source 220v inconnue lors d'un voyage qui pourrai mettre ma ligne AC IN en danger dans mon camping car.

Je vois certain diagramme Victron avec deux interrupteur differentiel et disjoncteurs avant et aprés un multiplus et d'autres qui n'en n'ont qu'une unité de protection sur AC OUT et rien en amont.

Est ce inutile de rajouter un disjoncteur differentiel ou non ?

Merci

Hi guys,

I'm trying to understand the AC-Out on the Multiplus 12/3000/12v. I've read the tech sheet and the manual and I'm still not clear.

The spec sheet says the "Maximum feed through current (A)" is 50A. Does this mean that the max current that can pass through AC-OUT-2 (that's the output that is pulled from the AC-IN and just passed through the inverter, I think?). In that case, the breaker I should have before AC-OUT-2 should be 50 AMPs right?

What's confusing is that in the "General" section of the spec sheet, it says "Auxiliary Output: Max 32A. Switches off when no external AC Source Available". So is it 50A or 32A or am I totally not understanding this.

Also, for AC-OUT-1 (the primary AC-OUTPUT) does a 30A breaker suffice? 3000w/110v = ~27A.

Thank you!

Luc

Bonjour

Quand mes batteries ont une limite de charge inferieure au réglage sur la console a distance (limite actuelle d'état de charge) le MULTIPLUS II recharge les batteries la nuit pour atteindre la limite supérieure (c'est normal) le problème est que cette recharge intervient aussi en heure pleine ! (mes heure creuse de 21h a 23h et 2h 8h) peut on choisir une plage horaire en heure creuse pour faire cette recharge ?

Merci

I am using Quatro 48/10000/140 inverter and would like to set battery settings for a combined 48V bank of 10s Axitech module (NCA) . I read an old post about such a setup showing battery settings but for the Axitech 7s/9s module. https://www.victronenergy.com/live/battery_compatibility:axistorage

so I want to know that can I use the same Absorption and float charge settings as in that article for the 10s Axitech modules or is it something diff ? In the tech manual for 10kVA Quatro , it has 57.6V Charge voltage 'absorption' (V) and 55.2 as Charge voltage 'float' (V) as per the manual , then setting 60.75V absorption as in the article makes no sense. From what I understand, it cant charge the battery bank above 57.6V for the absorption phase.

So what battery charging and other settings should I set for this Battery type inside VEconfigure? thank you

I have a system with 2 Quatros 12V with a bunch of Battleborn batteries. The RV has some LED light strips mounted under the counters. When the RV is on shore power everything appears to be fine however when I turn shore power off and switch to the Inverters the LED light strips start to flash/blink especially when they are dimmed. The more they are dimmed the more they flash but only on inverter power.

Any idea why that would happen and how I can correct it?
