Best way of integrating a battery switch with a lynx bus
Since Victron refuses to release the visio shapes (on the wrong grounds in my eyes - it has NOT hurt other like Cisco) I cannot provide a sketch which would have explained this better so I will have to try in words instead.
I'm looking for a good design that contains a Power in module first, followed by the shunt VE can module. After that there should be a battery switch and the chain then ends with one or more distributors.
suggestion to the product team: A Lynx power switch would be a nice extension to the product range

System shutdown and restart
My system shuts down when the sun is shining brightly but not when it’s cloudy. It always restarts straightaway. What could be the cause of that?

Boat battery management system design
Hi Victron community. We have a 43 foot boat that we are rewiring. First step was to install 480kW woth or solar panels and a Victron 100/50 Smartsolar MPPT. We currently have twin banks of 2 x 200AH Lead Acid batteries (12V) and a single 120AH battery that is used as the cranking battery for the genset.
We like the look of the cerbo GX Touch 50 combo as the core of the management system, and the Centaur 12/60 (3) looks like a great charger option. We are having extra alternators added to the new Volvo Penta D6 engines to help increase our electric output.
We ideally want to make the genset redundent and so are looking at the Phoenix 12/1600 Smart Inverter. The main question we have is whether we need Smartshunts on one/two or all three battery banks to ensure we can see flow in/out of all banks and devices. I assume we would not need this if the Centaur was "smart" and it would be great if there was a SmartCentaur, but none of the other chargers seem to be able to handle 3 battery banks. Is this all sensible assumptions?

Lithium SuperPack drop-in replacement feasibility
Hi, I've been reading though all the posted questions but can't find a clear answer.
I'm considering replacing the current AGM house bank on my boat with SuperPack batteries, and I'm trying to understand what it would involve.
Below an attempt to visualize my current setup:
[image]
I understand that I'll have to replace the shore charger for a Lithium one, but beyond that, is there anything else I would have to replace/modify, or will the SmartPacks be a simple "drop-in" replacement?
My main doubt is:
Since the BMS is integrated, what will happen if the batteries are fully charged and the engine/alternator is running? Is there a risk the BMS will trigger the over-charge protection and disconnect all the loads (e.g. loosing plotter and instruments when approaching an anchorage/marina)
Any other suggestion/input is highly appreciated, like: does the Argo Fet still make sense with the SuperPack, or should I replace it with an Orion-Tr DC-DC charger? Do I need a separate external BMS to protect the batteries from overcharging?
Thank you!

"Balkonkraftwerk" inkl. Speicher mit MultiPlus 48/500/6 möglich?
Hallo,
ich würde mir gerne ein so genanntes Balkonkraftwerk anschaffen. Im prinzip geht es nur darum, die PV nicht aufwendig beim EVU anmelden zu müssen. Wenn ich eine Leistung von weniger als 600W am Wechselrichter habe, dann bewege ich mich Gesetzeskonform und habe ein vereinfachtes Anmeldeverfahren, was ich als Privatperson selber machen kann.
Daher meine Frage: Kann ich mit dem MultiPlus 48/500/6 oder mit dem MultiPlus 48/800/9 eine Anlage inkl. Speicher aufbauen, die die Einspeisung ins öffentliche Netz verhindert? Also so wie beim Multiplus II in den Datenblättern dargestellt als "Topologie parallel zum Netz mit MPPT Solar-Lade-Regler". Auch mit Stromsensor und GX-Modul.
Ich wäre sehr dankbar für eine kleine Antwort, weil ich mir eine solche Anlage sehr gerne anschaffen würde.

Looking for engineering support
Hello, I have built a three phase 60Kw system with approximately 300 panels, four wind turbines. The system is based on 6 Victron quattros. This is a three phase system with two quattros in parallel per phase. 300KwH of batteries.
The system works well, but I would like to work with a real electrical engineer (aka not me) to document the schematic, move the DC system to a busbar system, implement a couple of automations, make sure all the system safety and managment are in place and ultimately make the system such that it can be built out in a container and shipped to specific sites.
Do you have any recommendations of individuals or companies who could help me ?

Can a Multiplus 24/5000 run a 2.2kW SCUBA compressor?
Hi all.
I'm currently designing a system for my sail boat that I would like to run a Bauer Junior II dive compressor (2.2kW) from a Multiplus 24/5000. My research so far has indicated that people typically spec a 8-9kW generator to handle the start up current of the compressor. In my case, I won't have any generator.
My research has dug up anecdotal evidence of a 5kW inverter (unknown brand) starting a Junior II with a smart softstart from Hyper Engineering. I'm hoping that Victron inverters, given their capability to do 200% for 30 cycles should be able to start the compressor without issue, however I'd like to be a little more certain before dropping the $$$.
Does anyone know of this being done successfully?
Could the MP 5k still start it, even if the ambient temperatures are a bit higher (40ºC)?
Any help is greatly appreciated.
Regards,
Justin

New System, do I have everything?
Having had Victron components in may last system, We went pretty much all Victron in the new system. I am just looking for some insight as to if I am missing anything. This has all gone in to our 2021 Grand Design 2800BH, that replaced the 2018 that was destroyed in a rollover last summer. I have purchased;
- 12V Multiplus 3000
-Victron Lynx Distributor
-Victron SmartSolar MPPT 150/100 (for the 4 275W31V panels)
-Victron Color Control GX
-Victron SmartShunt 500A/50mV
-Victron ASS000100000, temperature sensor (which as I understand works with the Smartshunt)
-To be paired with a Lithium 320Ah 12V
So aside from the 2 marine style kill switches and fuses, Am I missing things, such as the VE.Direct cable? I was lead to understand I could control things from CCGX. An further insight would help.

Big open ended question about a new design.
Sorry if this is too open ended for this forum.
Looking for help designing a new victron system for a boat.
Inputs:
4200 wats of Solar
Wind generator
Diesel generator
(2) 30amp dock lines from shore power.
Batteries:
Lithium-ion Batteries (Most cost effective reliable manufacture recommendation welcome)
Consideration:
Expect global travel. Would like to consider a power converter to convert what ever shore power is available (120 50/60, 220 50/60) to standard 12v marine system. Would of course need a charging system. I have seen several different displays out there for a system like this. Any recommendation for that is appreciated as well.
I am still learning so any resource or suggested design is welcome and greatly appreciated.

Help needed vetting initial design ideas for van electrical system
Newbie here, designing a van system.
I would like help vetting the big picture design. Once the big picture is solid, I will move onto current, distances, wire size, fuses, etc. I would really appreciate your comments, criticism, and suggestions on this big picture design.
The idea is to initially start with something without a lot of solar or a large battery bank. But design/build it so that solar and batteries can be doubled. Inverter, wires, and fuses, for example, would all be sized for this later use. A few years down the road, I will know a lot more about my system and my needs.
Random factoids:
- This is a passenger van, which will only be 'half converted', so I would like to keep the system smaller, particularly initially.
-
My 2020 Transit has a LOT of alternator power available (details in diagram).
-
Would prefer to keep my roof rack for things other than solar, for now anyway.
-
Do not want built-in propane. Will take propane/butane camp cookstove for longer trips.
-
Initially, will only use inverter cooktop/microwave occasionally - quick stop when pulling over on a road trip over, horrid weather, hot water/soup/heat up leftovers/etc. Am willing to not use when house batteries low, or when I know I will be off-grid for longer. In a few years, I will know more about whether this restriction is one I want to keep.
-
Traditionally, I don't tend to stay in one place for long, and with all that alternator power available, it is not obvious that I need a huge bank. Having said that, with all the kids we have now, this may change. Time will tell.
-
For the next few years, this van will only be for weekend camping trips, and road trips. A few years down the road, when kids older, it will be used more off-grid.
-
Would add an audible alarm, hooked up to inverter/charger, to warn when too much draw. I'm not the only one using this van, and others may not remember "the rules". Initial phase would probably have one and only one easily accessible AC outlet from (battery side of) inverter, to preclude running more than one heavy hitter at the same time.
-
All Victron, except for solar panels, and possibly batteries. I've been super impressed with the help and knowledge available in this community, and I like the fact that they play well together and have great monitoring. I'm willing to pay up front for something safe and reliable that I will not have to replace/fix later.
To keep this uncluttered, a lot of my thinking is 'encoded' in the diagram below. For example, at first I thought that with 2x 175w panels, I should be fine with an MPPT 100/30, which is supposed to be able to handle 400w. But once I started looking into online discussions about solar panels and cold morning startups, I came to understand that, as usual, it is not as simple as it seemed at first. Even with just 2x 175w panels, I might need the 100/50. I haven't bottomed out on that yet.
I would very much appreciate
-
A review of the possible "final" system - is it well balanced? Is there anything that stands out as unwise, unnecessary, or missing?
-
Opinions on this "initial" system approach... is this silly / crazy / wise / doable, but...? Any time caveats here? For example, you can go one or two years before buying second battery, but no longer, to avoid mixing battery ages.
Thanks much!!

Design pour un CC avec EBL existant
Salut les gens
Je suis de retour et en français cette fois, plus simple pour moi aussi !
J'ai apporté des modifications quant à la première conception postée sur forum anglais, y compris avec le matériel existant.
L'équipement existant, encadré en vert en bas à droite, est physiquement situé à l'intérieur du véhicule. Les lignes vertes partent de l'EBL119. L'EBL119 est une unité électrique d'origine et intégrée dans le véhicule. Elle est utilisée pour la distribution du courant 12V / 220V et pour la gestion d'une seule batterie de service cabine AGM ainsi que d'une batterie de démarrage. L'EBL119 n'accepte que du 12V / 220V. Je n'ai pas encore déterminé la section des câbles, mais cela dépendra aussi des longueurs, à voir sur place.
Dans mon précédent post sur forum anglais, on m'avait conseillé de passer du 12V au 24V pour tout le système. Mais au vu de l'EBL119 présent et que je veux garder pour la gestion de tous les éléments internes, frigo, éclairage, alimentation externe... je vais rester au banc 12V.
Mon objectif :
- Retirer les éléments encadrés par une ligne verte en pointillés ainsi que les lignes en pointillés verts: batterie de service et ligne directe 220V vers la distribution des prises.
- Laisser l'EBL119 en place mais en installant un interrupteur à 3 positions pour la distribution du 220V dans les 5 prises existantes du véhicule: 0- pas d'entrée de courant, 1- alimentation 220V par le convertisseur, 2- alimentation 220V de la connexion externe au véhicule.
- Recharge des batteries Lithium avec un Buck-Boost grâce à l'alternateur / Euro-6.
Reste à résoudre:
- Recharge du banc de batteries Lithium 12V par l'alimentation externe 220V de l'EBL119 ou directement par une alimentation séparée à un chargeur? Je ne connais pas encore le meilleur. Peut être avec un convertisseur / chargeur au lieu du seul convertisseur.
Ou pluôt, rester en 12V avec les batteries, comme ça, pas de souci avec l'EBL119 ( comme sur mon design joint ). Ou quand même mettre tout en 24V ( selon les commentaires apportés depuis le forum anglais ).....Argggg...je ne sais plus par où commencer ou plutôt finir...
Cela vous parle-t-il et suis-je sur la bonne voie?
Merci beaucoup pour vos fabuleux commentaires sur ce projet.

Your evaluation before installation
Hi Folks
Before installing my system in my motorhome, I wanted to submit to your experiences on this installation.
The green part is the support panel. The cables pass through the rounds to pass to the rear. This forms like a door with a hinge to facilitate assembly and to carry out subsequent additions of elements. The dimensions of all elements are exact dimensions in mm. The thin cables are in 2.5mm2 or VE.Direct or USB, the medium ones in 16mm2, the batteries in 35mm2. The battery fuses are 175 ANL. The red lines are + or Line or Phase, the black lines are - or Neutral.
No cables cross and the support panel is 80 cm x 60 cm, made of fireproof wood. Did I miss something in this assembly diagram?
I thank you in advance.

System Monitoring and Diverting loads
Hi - forum newbie here,
I'm looking at upgrading my off grid set up and welcome comments on the proposed works.
I'm keen to take advantage of the solar generation when my battery bank is charged (see No 7 below) and am still looking for solutions. This is one of the main things I'm struggling with so if anyone can help that'd be fantastic.
Having a way to monitor the whole system would also be great. Currently no comms leads run between any of the Victron kit. Maybe there's a monitoring solution built in to the multiplusII - which I haven't found time to fully research yet. So any pointers on how these devices should be talking to each other is also gratefully received.
And the other main thing I'm struggling to find is a resistive element solution that can be wall mounted for my ballast load - which would replace my elecky convection heaters (see No 6 below).
I've included a sketch of my existing and proposed layout to help with the context. The rational behind these changes is to upgrade some of the 9 year old components, to switch from a flooded lead acid to LiFEPO4 battery bank, add heating to the small outbuilding (approx 40 sq m) as part of the renovation works, optimise how things are configured and be able to monitoring the system.
Proposed Upgrade Info
- Upgrade inverter to a Victron Multiplus II
- Upgrade battery bank to a 48v 16s 2p prismatic battery solution using 280Ah cells, add a BMS - possibly from overkillSolar, new enclosure with low temp heating solution. Batts will probably be imported from China via AliExpress or Alibaba.
- Install a new change over unit to create an additional route for the ballast load from the existing hydro. This would divert the ballast to heat water for under floor heating in an outbuilding that's slowly being renovated. I've an M&E engineer who'll build this for me.
- Install a new 250l unvented tank. Possibly something from Gledhill.
- Install a new pico hydro scheme that’s designed to run in our wet Welsh winters to generate hot water. Probably using an off the shelf solution like PowerSprout, AmpHydro or StreamEngine
- Upgrade resistive ballast elements to a wall mounted solution. Still looking and struggling to identify components that could work.
- Identify a solution to harness energy from the solar PV when the batts are fully charged and also have a way to monitor the entire system.
If anyone spots any errors, has suggestions or can offer any input, all comments are encouraged and welcome.
Thanks in advance

Hi - forum newbie here,
I'm looking at upgrading my off grid set up and welcome comments on the proposed works.
I'm keen to take advantage of the solar generation when my battery bank is charged (see No 7 below) and am still looking for solutions. This is one of the main things I'm struggling with so if anyone can help that'd be fantastic.
Having a way to monitor the whole system would also be great. Currently no comms leads run between any of the Victron kit. Maybe there's a monitoring solution built in to the multiplusII - which I haven't found time to fully research yet. So any pointers on how these devices should be talking to each other is also gratefully received.

System design help (Marine)
Hi, At present I only have a Victron Smartsolar MPPT 75/10 solar controller. I want to add a battery monitor and display. I am considering the Cerbo GX, the GX touch display and a 500A smart shunt. Are these items all compatible with the 75/10? I also want to future proof the system as much as possible to add Victron charger/ inverter etc at a later date. Any advice appreciated.

Victron 100/50 + Inverter Wiring Setup Help?
Hey guys, this is the very simple setup I intend to run in the coming weeks - can you please help me with the following:
[image]
1. Should I have a circuit breaker (as depicted)? And/or, any other protective devices in the diagram - and if so, what type/rating?
2. The system will be contained within a car for 85% of the time, I assume I should Ground the Inverter and MPPT to the vehicle (wherever I can find good contact). Though, the other 15%, it will be completely standalone at a campsite without being grounded...which I assume is the case for many setups?
3. The Panels come with some 12 Gauge, I assume that's fine to run there on? 4. ...anything wrong with the setup, improvements, suggestions?
Many thanks in advance - I really appreciate it (particularly @seb71 for getting me on the path :) ).

Hoping for opinions on full Victron RV system plan
Dear all,
as I am new with all Victron components and quite francly electrics in general, I would really appreciate some opinions on my system plan. I have already put a lot of effort into this and read lots of articles and info but in the end every system is individual in itself and I am by far no expert yet.
I am planning to install all this into a bus that I am currently converting into an RV in Germany. I'm saying that to make clear that there is no current "house electricity" in the bus except cables throughout the walls to all appliances and outputs. For all 12V wiring I ran positive AND negative wires, so I guess the Orion DCDC converter might be an unneeded add-on in my case.
I don't really have many specific questions anymore. I was more hoping for someone with experience in Victron equipment to approve/or help improve my plan.
The only specific questions I am left with concerns the 4A trickle charge output of the Multiplus. Is it okay to just hook this up to my start battery positiv or do I need to be concerned about overcharging this battery once full?
I thank everyone who might get involved and look forward to any input you all might have.
Cheers,
Doran

Can I connect 2 victron systems together?
Thru upgrades of some components, I am left with enough parts for 2 PV systems.
System1
- MPPT 150/60, 12 x 285W panels
- Quattro 48/5000
- Pylontech batteries
- Cerbo
System2
- MPPT 150/60, 4 x 450W panels
- Multiplus 48/3000
- BMZ batteries
- need another Cerbo?
The question is: how to connect these 2 systems? One option would be to use System2 AC Out to connect to System1 AC In-1. System1 AC In-2 would be connected to the grid. System2 would not be connected to the grid (or should it?).
This is the best I can think of on my own, but I'm sure there are better options. My goal is the best possible energy management. System1 panels are primarily active in the morning, whereas System2 panels are active in the afternoon.
Can you please comment? Thank you...

Autark electricity in our expedition truck
Dear community
We are building a expedition / world traveling vehicle and are now in the process of defining the electrical components. We plan to travel without LPG, therefore we have a extended need on autark electricity (4 weeks autark time).
Our requirements:
- Run 4 induction pads (2 x 3.7 kW)
- Run electrical oven
- Run AC with 1800W
- Run fridge / freezer 2 kW/24h max.
- Run standard washing machine
- Run water heater
- Run 2 diesel heaters
- Run 1 TV 48"
- Run all lights, water pumps, NAS, charge phones, laptops, cameras, etc
- We want to have 2 fully redundant systems 400Ah/24V and 800Ah/24V
Charge:
- Solar with 2,6 kWp panels
- Charge booster (light machine of the truck, max. 100A/24V)
- Land electricity 230V AC
- Land electricity 110V AC
To stay independant, we decided for 1200Ah / 24V battery capacity LiFePo.
We would like to have all components from one provide and are convinced that VictronEnergy is a great partner!
Now my questions:
- What is better: 6 x 200Ah/24V or 12 x 200Ah/12V?
- Would VE provide a list of components and schema how to connect the components?
- What are the most important questions to ask?
Looking forward to feedback

Sanity check please...
Hi there,
I'm wondering if I can get some feedback about my proposed system. Diagram is below. My concerns are about whether I should be using the Cyrix-ct battery combiner instead of an ArgoFET isolator. Should the MPPT controllers feed to the start battery? as well as the house batteries?

Victron powered van conversion - requesting a review of my diagram
Hi all. I've been spending some time figuring out the power system for my van conversion. I'm pretty confident I've covered all the components I need, an their position in this van ecosystem and have sized wires and cables according to my best amateur-level understanding on the subject. I've placed a star on the components I've already purchased or ordered in the attached image: MultiPlus, MPPT, Orion, Cerbo + screen, Smart Shunt and the batteries. I also understand that the Orion-Tr is not so smart that it could be connected via VE.Direct to the Cerbo. Location of the system will be within a square meter at the back of the van and the longest run would be the 5m starter battery cable from the cabin to the rear of the van and of course the pv panels on the roof.
The most uncertain component of the system is the PV array; I have limited space on the roof due to planned skylight and MaxxFan. Also I want to deck a small area of the DIY roof rack I'm building. I want to have a minimum of ~600Wp of solar, pushing as close to the MPPT's capacity as possible and the PV panels shouldn't exceed 1480mm x ~600mm dimensions. So far, the OffgridTec 150Wp modules seem to have the highest output of this module size I've seen, given they are a bit pricey though.
I'm also not 100% sure if I can connect all the Victron components via Victron Connect App. I understand Orion-Tr Smart, MPPT Smart, Smart Shunt and MultiPlus (with the VE.Bus Smart Dongle) can connect to the App, but the Cerbo can't. I'm planning to connect mainly via the App, but also would want to be able to access the system via VRM Portal when outside BT range (via the Router). The Cerbo display goes to the cabin and provides redundancy in case BT is not working or I lose my phone. I also have an Android 10" head unit (posted a question about it some time ago), so would be interesting to connect that unit to the system as well via BT or mirroring the Cerbo display.
So, I'm seeking some constructive criticism from you experienced Victron users on this set-up.
-have I overlooked, misplaced, miss-matched, miss-sized something in the main components of the design? Is there something I should change in order it to work better, or at all?
-is it possible to connect non-Victron components with the VictronConnect App, namely the two LiFePO4 -batteries?
-are there any good alternatives for the OffgridTec 150Wp panels in 2S2P that you'd know of? Could also be 3 x 200W in1S minding the size restriction.
Thanks in advance!

Choosing between one large inverter or two smaller for US 120-0-120 split phase

Being in the US, we need 120-0-120 split phase of course. Can anyone show the pros and cons between the two options here ?
* One large 230V Quattro to take in 240V from grid, 240V from gen (neutral not connected), spit out 240V to 100A autotransformer to sub-panel for two L1/L2 120V supplies.

Request: Blue Smart - Add tail current to expert mode
Can the devs please add the ability to set end of absorption tail current in the Blue Smart charger lineup when in expert mode? This would be extremely helpful to prevent premature switch to float without relying on fixed absorption and the risk overcharging when doing that.
It appears that this was at least thought of at some point given in the Absorption duration settings it directs a user to disable the tail current setting when using fixed absorption.
If this is done PLEASE allow tail current setting to be dropped below the .50% level that is in the smart shunt (and maybe other products). Odyssey batteries want to see .02% of tail current to end absorption.
