How do I use the digital inputs in cerbo GX

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,

interrupteur differentiel multiplus


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 ?

Understanding Multiplus 12/3000/12 AC-Out

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!

CCGX LCD Panel Has Stopped Working


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.

Cerbo GX Water Tank Level Sensor Recommendations Needed

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.

Quatro 48/10000/140-100 compatibility with Axitech Li 10s


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.

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

LED Light strips blinking when on inverter

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?

Multiplus2 Integration

Hallo Gemeinde,

ich habe nun den Multiplus2 mit VE Config parametriert. Im Anhang sende ich die Zusammenfassung. Der Multiplus nutzt gemäß seines Standorts den französischen Netzcode.
Der nächste Schritt wäre nun der physische Anschluss des MP2. Geplant habe ich ja die Phase 1 komplett über den MultiPlus laufen zu lassen um im Falle eines Netzausfalls alles auf Ersatzstrom zu haben was daran angeschlossen ist. Heizung, Licht, Telefon, Kühlschrank, etc.
Dafür trenne ich die vom Netz kommende L1 und N von der Hauptverteilerklemme und führe beide auf AC in. Dann verbinde ich AC out 1 L und N zurück auf die Hauptverteilung. Die Zuleitung zum MP sichere ich mit einem Leitungsschutzschalter 25A Kat. B ab.

Ich habe 2 Pylontech US2000 95 B V.2 zum Speichern, 4,8 kW/h

Ist dann der ESS Assistent die richtige Wahl, da es sich dabei nicht um eine reine netzparallele Installation handelt?
Wie vermeide ich Batterienutzung, wenn, wie in den letzten 4 Monaten nichts vom Himmel kommt?
Wie kann ich den Batteriestrom auf z. B 1000 W begrenzen (dreifache Grundlast) und den Rest auch auf L1 aus dem Netz beziehen?

Gibt es Gründe die gegen eine solche Einbindung des Multiplus sprechen? Gibt es etwas zu beachten bei Nutzung des Drehstroms?

Ich brauch die drei Phasen normalerweise nur für meine 400V Drehstrommotoren. Mein Kochfeld nutzt noch Phase 2 und mein Backofen noch Phase 3. Mein jährlicher Stromverbrauch liegt derzeit bei 2500 kW/h.

Vielen Dank für eure Gedanken und Hilfe zu dem Thema.

Phoenix Smart charger goes straight to absorption


I have a Phoenix Smart Charger IP42 50A 1+1 that I am using to charge my lithium bank (not victron, DIY build).
My problem is that only minutes after switching on the charger, even if batteries are almost empty, the charger goes to absorption stage. The voltage (as shown in screenshots below) have not reached my set absorption voltage. The charger is not charging at max capacity, not is it charging at any constant voltage. The voltage changes slightly up and down. I don't see how this should be possible?



I really just want my charger to go full power constant current until my BMS system switches it of. I have set the absorption voltage higher in the charger than in my BMS. I do not want to use the supply function in the charger since I like the fact that the settings in the charger will protect my batteries should the BMS fail somehow.


Now the absorption timer kicked in and it transitioned to float. Dropping the voltage and charge current even more.... :-(

Still nowhere near absorption voltage I set...

It’s 2022. Is configuring a MultiPlus with Mac or iPad possible yet?

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.

(2)-Multis configured to accept both 120v common leg and 120v dual leg.

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.

CCGX with Smart Shunts, MPPT and without inverter/charger


I am thinking of putting together a boat system with CCGX, 3x Smart Shunts and SmartSolar MPPT. System also has DC loads and a BlueSmart battery charger (3 outputs), but this can not be connected to the CCGX. System has no AC loads. I am not thinking of buying an inverter/charger anytime soon which would be connected to the VE.Bus input on the CCGX.

My question is, will the CCGX function with three Smart Shunts and one MPPT connected to it without anything connected to the VE.Bus input? How do I know what the display will show with this kind of setup? My goal is to have one display (instead of two or three BMV-s) for my starter, house and bow thruster batteries (batteries are separated by battery isolators) which displays not only voltage but also state of charge. I want to see the status of MPPT and send all this info to the helm to a Raymarine MFD

In all example schematics and articles I can find about CCGX, there is also input on VE.Bus from some inverter/charger present and I am afraid to make the investment without knowing if the CCGX will work wihtout anything connected to the VE.Bus port.

Unable to set shore power above 32A

Using a Multiplus II 3000 in an ESS configuration, and using scheduled charge settings to make the most of low cost off peak power at night.

I've noticed when loads are high, charging a car for example, scheduled charge does not charge the batteries, in fact the multi inverts to help out, thus draining the batteries.

I think this is because the shore current setting has a max of 32A, when my loads go over this the multi "helps out".

A this is a ESS, and the house is fitted with a 100A fuse i want to be able to set the shore power above 32A, in VE Configure.

Victron charger overcharge batteries, resulting in exploding battery

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.



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.
